The charged parts of the atom are the

1) The potential energy is the most at the highest position and the least at the equilibrium position

2) The kinetic energy is the most at the equilibrium position and  the least at the highest position

Explanation:

1)

The potential energy of an object is the energy possessed by the object due to its position in a gravitational field; mathematically, it is given by

[tex]PE=mgh[/tex]

where

m is the mass of the object

g is the strength of the gravitational field

h is the height of the object relative to the ground

For the pendulum in this problem, m is the mass of the bob, and h is the height of the above relative to the ground. We see from the formula that the potential energy is directly proportional to the height:

[tex]PE\propto h[/tex]

This means that:

2)

We can solve this part by applying the law of conservation of energy: in fact, the total mechanical energy of the pendulum (sum of potential and kinetic energy) is constant at any time during the motion,

[tex]E=KE+PE=const.[/tex]

where KE is the kinetic energy.

From the equation above, we observe that:

Therefore, this implies that:

To determine the amount of heat passing through the walls of the container, we can calculate the rate of heat transfer through conduction using the formula q = k * A * (T2 - T1) / d. Once we have the rate of heat transfer, we can multiply it by the time to find the total heat transferred.

To determine how much heat passes through the walls of the container, we need to calculate the heat transfer through conduction. The rate of heat transfer can be calculated using the formula q = k * A * (T2 - T1) / d, where q is the heat transfer, k is the thermal conductivity of the material, A is the surface area, T2 is the temperature outside the container, T1 is the temperature inside the container, and d is the thickness of the walls. We can then multiply the rate of heat transfer by the time to find the total heat transferred. In this case, the temperature outside the container is 35.0°C and the temperature inside the container is 0°C.

Let's calculate the heat transfer rate:

q = k * A * (T2 - T1) / d

Assuming the thermal conductivity of the plastic-foam material is known and given, we can substitute the values into the equation and calculate the rate of heat transfer. Once we have the rate of heat transfer, we can multiply it by the time to find the total heat transferred.

To determine the height at which the speed of the ball decreases to one-half of its initial value, we need to consider the vertical motion of the ball. By finding the time it takes for the ball to reach its maximum height and the time it takes for the speed to decrease on its way down, we can calculate the height above the launch point.

The question is asking at what height above its launch point the speed of the ball decreases to one-half of its initial value. To determine this, we need to consider the vertical motion of the ball. Let's assume the launch point is at a height of 0 m.

Answer:

C) Gravity and drag

Explanation:

Here we are considering the ball after it has been hit by a bat.

When the ball is in the air, there are only two forces acting on it:

The weight of the ball (force of gravity), acting downward. Its magnitude is given by , where m is the mass of the ball and g is the acceleration of gravity

The air drag, which is the resistance of the air on the ball, acting downward as well (it acts against the direction of motion of the ball). The magnitude of this force is proportional to the speed of the ball

There is no applied force on the ball, since that one only acts on the ball when it is in contact with the bat - however, when the ball is in the air, the applied force no longer acts on the ball.

Therefore, the correct answer is

The amount of gravity between 1 kg of lead and Earth is the same as the amount of gravity between 1 kg of marshmallows and Earth.

Answer: Option C

Explanation:

According to universal law of gravity, the gravitational force is directly proportionate to the product of masses of the interacting objects and inversely proportionate to its distance squared between them.

Since the mass of Earth is very high compared to the mass of the other objects, be it lead or marshmallows, and the distance will be mostly same. Thus, there will be no change in the amount of gravity acting between them. Thus, the amount of gravity between 1 kg of lead and Earth is the same as the amount of gravity between 1 kg of marshmallows and Earth.

The amount of gravity between 1kg of lead and the Earth is the same as between 1kg of marshmallows and the Earth. The amount of gravity depends on the mass and distance, not on the material of the objects. This is based on Newton's law of universal gravitation.

The amount of gravity that the Earth exerts on an object doesn't depend on the material of the object, but it does depend on the mass. Since both the 1kg of lead and the 1kg of marshmallows have the same mass, then the amount of gravity between them and the Earth is the same.

This principle is reflected in Newton's universal law of gravitation, expressed as F=G*(m1*m2)/r^2, where F is the force of gravity, m1 and m2 are the masses of the two objects, r is the distance between their centers, and G is the gravitational constant. Regardless of whether the object is made of lead or marshmallows, if the mass remains the same as 1kg, then the gravitational force, hence the gravity between the Earth and the object, will also be the same.

So, to answer your question, the amount of gravity between 1kg of lead and Earth is the same as the amount of gravity between 1kg of marshmallows and Earth.

Mechanical energy is conserved in all the four situations

Explanation:

The law of conservation of energy states that in absence of non-conservative forces (such as air resistance of friction), the mechanical energy of an object is conserved.

The mechanical energy of an object is the sum of its potential energy (PE) and its kinetic energy (KE):

E = PE + KE = const.

Cause removing excess waste from the body helps to maintain a steady health

Final answer:

The excretory system's role in removing excess waste is critical for preventing disease and supporting cell function by maintaining a balanced internal environment and removing harmful substances.

Explanation:

The excretory system plays a crucial role in maintaining the overall health of the body by ensuring the removal of excess waste and toxins. This system includes organs such as the kidneys, liver, skin, lungs, and large intestine. The kidneys filter blood, removing waste products and excess substances, forming urine which is then excreted from the body.

The skin eliminates waste through sweat, the liver metabolizes toxins and excretes bilirubin, the lungs expel carbon dioxide and water vapor, and the large intestine helps to remove solid waste. By doing all this, the excretory system helps prevent the accumulation of harmful substances which could lead to disease and supports the function of cells by maintaining a stable internal environment.

Removing excess waste helps to prevent disease by eliminating toxins that can damage tissues and cells. It also supports cell function by maintaining a balance of water, salts, and organic substances within the body. Therefore, the correct answer to the question is: d. Removing excess waste helps prevent disease and supports cell function.

Answer:

The tangential acceleration is zero

Explanation:

Tangential Acceleration

It's a measure of how fast is the tangential velocity changing when the object has rotational motion. It's perpendicular to the centripetal acceleration and equal to the product of the angular acceleration by the radius of rotation. In a uniform circular motion, the angular speed is constant, i.e. the angular acceleration is zero.

If the tangential acceleration was different from zero, the rotating object would change its angular and tangential velocities.

The turntable is rotating at a constant speed, so, regardless of the position of the mint, its tangential acceleration is zero

1) Final velocity: 0.8 m/s to the left

2) This is not an elastic collision

Explanation:

1)

We can solve this problem by applying the law of conservation of momentum: in fact, if there are no external forces, the total momentum of the two cans must be conserved before and after the collision.

Mathematically:

[tex]p_i = p_f\\mu_1 + mu_2 = mv_1 + mv_2[/tex]  

where:  

m is the mass of each can

[tex]u_1 = -4 m/s[/tex] is the initial velocity of the first can (we take to the left as negative direction)

[tex]u_2 = 2 m/s[/tex] is the initial velocity of the second can (to the right, positive)

[tex]v_1 = -1.2 m/s[/tex] is the final velocity of the first can (the hickory one)

[tex]v_2[/tex] is the final velocity of the 2nd can (the hot and spicy one)

Re-arranging the equation and solving for v2, we find:  

[tex]v_2 = u_1 + u_2 - v_1 = (-4) + (+2) - (-1.2)=-0.8 m/s[/tex]

So, the final velocity of the hot and spicy can is 0.8 m/s to the left.

2)

There are two types of collisions in physics:

In order to check if this collision is elastic or not, we need to compare the kinetic energy before the collision to the kinetic energy after the collision.

Before the collision:

[tex]K_i = \frac{1}{2}mu_1^2 + \frac{1}{2}mu_2^2 = \frac{1}{2}m(-4)^2+\frac{1}{2}m(2)^2=10m[/tex]

After the collision:

[tex]K_f = \frac{1}{2}mv_1^2 + \frac{1}{2}mv_2^2 = \frac{1}{2}m(-1.2)^2+\frac{1}{2}m(-0.8)^2=1.04m[/tex]

We see that the final kinetic energy is less than the initial kinetic energy: part of the kinetic energy has been converted into other forms of energy during the collision, therefore this is NOT an elastic collision.

Answer:

We can conclude 2.3x10^7 J was converted to thermal energy

Explanation:

Energy Conservation

According to the law of conservation of energy, the total energy of an isolated system must be constant. If some kind of energy is 'lost', we know it was transformed into another type.

Let's check the conditions of the problem. The ride vertically drops a distance of 71.6 m starting from rest, and at the bottom of the drop, its speed is 10 m/s. Knowing the mass of the cart plus passengers is 3.5X10^4 kg, we compute the total energy at the top of the drop.

[tex]E=U+K[/tex]

Where E is the total energy (which must be conserved) at the top of the drop, U is the gravitational potential energy and K is the kinetic energy. We use the equations for each:

[tex]U=m.g.h[/tex]

[tex]\displaystyle K=\frac{mv^2}{2}[/tex]

[tex]\displaystyle E=m.g.h+\frac{mv^2}{2}[/tex]

At the top, the speed is 0, thus

[tex]\displaystyle E=m.g.h=(35000)(9.8)(71.6)=2.5X10^7\ J[/tex]

Now we compute the 'total' energy at the bottom (quoted because we know there is some mechanical energy loss in the drop)

[tex]\displaystyle E'=m.g.h'+\frac{mv'^2}{2}[/tex]

This time h'=0 and v=10 m/s, thus

[tex]\displaystyle E'=\frac{(35000)10^2}{2}=1.8x10^6\ J[/tex]

The mechanical energy at the top and the bottom are not the same, thus we can know part of it was converted to heat or thermal energy. We compute the difference

[tex]2.5x10^7\ J-1.8x10^6\ J=2.3x10^7\ J[/tex]

We can conclude 2.3x10^7 J was converted to thermal energy

The time required for a bicycle to travel the distance of 100 m is 50 s.

Explanation:

We know that speed is the measure of how fast an object can move to cover a given distance in given time. So it is measured as the ratio of distance per unit time.

            [tex]Speed =\frac{\text { Distance }}{\text { Time }}[/tex]

As it is scalar quantity, direction does not play any role in it.

So time taken for covering the distance of 100 m with speed of 2 m/s can be determined as

           [tex]Time =\frac{\text { Distance }}{\text { Speed }}=\frac{100}{2}=50 seconds[/tex]

Thus, 50 s will be required by the bicycle to cover 100 m distance.

Both are correct since sound waves are mechanical waves.

Option: D.

Explanation:

A wave is a recurring event that transfers energy through vibrations. It caused by the disturbance movement in a medium. The medium can be solid, liquid or gas and it can come in many forms and shapes.  

If the particles in the medium moved in the perpendicular direction to the wave is called transverse wave and if those particles moved in the parallel direction to the wave then it is a longitudinal wave.

Mechanical waves require a medium to transfer that energy. Moreover, based on the medium properties ( inertial and elastic) it can be changed as either transverse or longitude.  

In, sound wave the particles will move in the parallel direction to the wave. Also, it comes under mechanical wave since it requires an air medium to travel.

Plate A and Plate B are both made of continental plate material where they touch. What will happen as the plates press together? The edges of both plates will be pushed upward as the plates continue to move toward each other.

Explanation:

When two continental plates collide with each other and they fold the rock at the boundary, lifting up, and leading to the formation of mountains and mountain ranges.

Tectonic plates are pieces of the crust of the earth and the uppermost mantle, together referred to as the lithosphere. The plates are around 100 km thick and consist of two types of material: oceanic crust and continental crust which generally have silicon and aluminum.

When two continental plates collide, the edge of one plate is thrust onto that of the other plate. The rocks in the lower slab undergo changes in their mineral content due to heat and pressure and will probably become exposed at the surface.

Rocks changed to new mineral assemblages due to changing temperatures and pressures are known as metamorphic. The regions of the crust undergo melting and subsequent extrusion of melt magma appears at the surface as volcanic rocks that rise to form granites at high crustal levels lead to the formation of mountains.

Explanation:

The given statement is true.

Secondary succession refers to the series of community changes that take place on previously established but damaged or disturbed habitat.

It helps in reviving or re-establishment of the similar ecosystem that previously existed.

It starts by a disturbing event such as natural disaster (hurricane, tornado, earthquake et cetera) and human interventions (deforestation, accidental forest fires caused by human activities, habitat destruction due to mining or dam construction et cetera) which greatly reduce the ecosystem already established.

Human impact on ecosystems often leads to secondary succession rather than primary succession.

In ecosystems, primary succession occurs in areas that were previously devoid of life, such as newly formed volcanic islands or bare rock surfaces. Secondary succession, on the other hand, occurs in areas that have been disturbed but still retain some soil or remnants of the original community.

Human impact on ecosystems often leads to disturbances such as deforestation, fires, or agriculture. These disturbances create conditions for secondary succession rather than primary succession, as there is generally still some soil and seed bank present.

For example, if a forest is clear-cut, the remaining soil and seeds in the area can allow for the regrowth of vegetation, leading to secondary succession.
