Answer:

2

Explanation:

There are 2 chlorine atoms in AgCl₂.  So to balance the equation, there needs to be 2 atoms on the left side as well.

Final answer:

The question likely contains a typo, as AgCl2 is not a standard chemical compound. Assuming a standard compound AgCl, the balanced equation would require two silver atoms and one chlorine molecule to produce two units of AgCl.

Explanation:

The chemical equation provided in the question seems to have a typo since AgCl2 is not a common chemical compound, as silver typically forms AgCl. Assuming the intention was to balance a reaction forming AgCl, the balanced equation would look like this:

Here, you need two silver (Ag) atoms and one chlorine (Cl2) molecule to produce two units of AgCl. Each chlorine molecule provides two chlorine atoms, which combine with the two silver atoms to form two AgCl units.

If the typo is ignored and we consider AgCl2, balancing a non-standard chemical equation may not be possible since the compound is not representative of known stable silver chlorides.

Answer:

In Newton's 1st Law, a stationary body or that moving with a uniform motion, will only change its state if acted upon by other external forces.This restance to change in position/motion is called inertia. In his second law, when a body is acted upon by a force, the force will be equal to the product of mass and acceleration of the body.i.e. Force= m.a. In the third law, it explains that a body will exert an equal and opposite force when intracting with another body.Here, every action force experiences an equal and opposite reaction force, where the momentum of the bodies will be conserved.

Answer:

Tangential speed of objects on the planet’s surface = 241 m/s

Explanation:

Speed is given by the ratio of distance traveled to the time.

Radius of mars, r = 3397 km = 3.397 x 10⁶ m

Distance traveled = 2πr = 2 x π x 3.397 x 10⁶ = 2.13 x 10⁷ m

Time taken = 24.6 hours = 24.6 x 60 x 60 = 88560 s

[tex]\texttt{Tangential speed =}\frac{2.13\times 10^7}{88560}=240.51m/s[/tex]

Tangential speed of objects on the planet’s surface = 240.51 m/s = 241 m/s

The tangential speed of objects on Mars' surface is approximately 242 m/s, calculated using the planet's circumference and rotation time.

To calculate the tangential speed of objects on Mars' surface, we first find the circumference of Mars using the formula:

Circumference=2π×radius=2π×3,397km≈21,371km.

Next, convert the time taken for one rotation from hours to seconds:

24.6hours×60minutes/hour×60seconds/minute≈88,560seconds.

Now, calculate the tangential speed using the formula:

Tangential Speed=  Circumference / Time taken for one rotation

​Tangential Speed≈ 21,371km / 88,560seconds ≈0.2417km/s≈241.7m/s.

Rounding to the nearest whole number, the approximate tangential speed of objects on Mars' surface is ≈242m/s.

Answer:

The mile

Explanation:

this is calculated using the metric system in kilometers..

Final answer:

None of the listed units (the mile, the ounce, the dollar, the pound) are based on the metric system used in the United States; these are all part of the customary or English system, except for the dollar, which is a currency.

Explanation:

None of the units mentioned - the mile, the ounce, the dollar, or the pound - are based on the metric system. These are all part of the English (Imperial) system of measurement that is primarily used in the United States. The metric system units for length, mass, and volume would be the meter (m), kilogram (kg), and liter (L), respectively. Meanwhile, the mile, ounce, and pound pertain to customary units of length and mass used in the U.S. which are based on the system developed in England. In contrast, the dollar is a unit of currency and not a unit of measurement for physical quantities.

When dealing with units used in science, the metric system is generally preferred because it facilitates easier conversion and calculation due to its base 10 structure. For example, a meter is approximately 1.1 yards, a kilogram is equivalent to about 2.2 pounds, and the second is the same in both the metric and American systems. In science, SI (International System of Units) units are used, which are metric units.

Answer:

The temperature of the system increases.

Explanation:

As we know that in adiabatic process the heat transferred to the system must be zero

now by first law of thermodynamics we know that

[tex]Q = \Delta U - W[/tex]

now we know that

Q = 0 (for adiabatic process)

now we have

[tex]\Delta U = W [/tex]

as we know that gas is compressed so the work is done on the gas which shows W is positive

So here change in internal energy must be positive which shows that temperature must be increased

so correct answer will be

The temperature of the system increases.

Answer:

6 cm

Explanation:

The weight of the water displaced equals the weight of the cube.

mg = ρVg

m = ρV

The mass of the cube is its density times its volume, and volume of a cube is the side length cubed.

The volume of the water displaced is the area times the depth.

(300 kg/m³ * (0.20 m)³) = (1000 kg/m³) ((0.20 m)² h)

2.4 kg = 40 kg/m h

h = 0.06 m

h = 6 cm

So 6 cm of the cube will be underwater.

Answer:

D

Explanation:

Snell's law states:

n₁ sin θ₁ = n₂ sin θ₂

where n is the index of refraction and θ is the angle of incidence (relative to the normal).

The index of refraction of air is approximately 1.  So:

1 sin 40° = n sin 25°

n ≈ 1.52

Theindex of refraction of glass is calculated to be 1.52, which is option D.

To find the index of refraction of glass when a light ray in air is incident on an air to glass boundary at an angle of 40 degrees and is refracted in glass at 25 degrees with the normal, we use Snell's law. Snell's law is expressed as n1 sin(θ1) = n2 sin(θ2), where n1 and n2 are the indices of refraction of the first and second mediums, respectively, and θ1 and θ2 are the angles of incidence and refraction, respectively. Given that the index of refraction of air (n1) is approximately 1, we can solve for the index of refraction of glass (n2) as follows: 1 ×sin(40 degrees) = n2 × sin(25 degrees). Solving this equation gives us n2 = 1.52, which indicates the index of refraction of the glass is 1.52, corresponding to option D.

Answer:

Negative because the graph goes down

Explanation:

Explanation:

They have different temperatures.  Heat always flows from high temperature to low temperature.

Average speed = (total distance) / (time to cover the distance)

total distance = (53 km + 54 km) = 107 km

time = (2 hr + 4 hr) = 6 hours

Average speed = (107 km) / (6 hrs)

Average speed = (107/6) (km/hrs)

Average speed = 17.833... km/hr

Explanation:

The first Newton Law of Motion states that an object at rest or describing a uniform straight line motion (moving at constant velocity), will remain at rest or moving unless a force is applied to it and changes its state of rest or motion.

According to his law, an object in rest can be in equilibrium (net force equals to zero), and a moving object can also be in equilibrium, as long as it keeps a constant velocity.

So, in the case of the toy car the forces acting on it (considering there is equilibrium between the normal force and the weight of the toy) are:

F1=50 N in the direction of the movement of the car

F2=-5 N (in the opposite direction of the movement of the car, that s why it has the negative sign)

Therefore the net force F is:

F=F1+F2=50N - 5 N

F=45N

Momentum before = momentum after

(1,000 kg) (0 m/s) + (1,000 kg) (10 m/s) = p

10,000 kg m/s = p

Answer is A.

Answer: The answer is A.

Okey, here we need to use the conservation of momentum!

(in the text and the image the masses are different, i will use the one of the image)

the total momentum before the collision is:

P = momentum of car 1 + momentum of car 2 = 0m/s*1000 kg + 10 m/s*1000 kg.

so the initial momentum is 10000 kg*m/s.

Because the system is isolated, and we will think that there is no loss of energy because of friction or anything like that, the momentum will conservative after the collision ( in a real situation the cars will absorb some of the energy in the collision).

So using the conservation of momentum, the momentum after the collision must be the same as before, so the answer is A = 10000 kg*m/s.

It is given that,

A spaceship hovering over the surface of Venus drops an object from a height of 17 m, h = 17 m

Acceleration due to gravity on the surface of Venus, [tex]g'=8.87\ m/s^2[/tex]

The second equation of motion is given by :

[tex]s=ut+\dfrac{1}{2}gt^2[/tex], u = 0

[tex]s=\dfrac{1}{2}gt^2[/tex]

[tex]t=\sqrt{\dfrac{2s}{g'}}[/tex]

[tex]t=\sqrt{\dfrac{2\times 17}{8.87}}[/tex]

t' = 1.95 s..............(1)

Acceleration due to gravity on the surface of Earth, [tex]g=9.8\ m/s^2[/tex]

Again using second equation of motion to find the time taken on the surface of earth.

[tex]s=ut+\dfrac{1}{2}gt^2[/tex], u = 0

[tex]s=0+\dfrac{1}{2}gt^2[/tex]

[tex]t=\sqrt{\dfrac{2\times 17}{9.8}}[/tex]

t = 1.86.................(2)

Change in time, [tex]\Delta t=t'-t=1.95-1.86=0.089\ s[/tex]

So, on the surface of earth it will taken 0.089 seconds more. Hence, this is the required solution.

Final answer:

When an object is dropped from a height on Venus, it takes longer to reach the surface compared to Earth due to the smaller acceleration due to gravity on Venus. It takes approximately 1.56 times longer for the object to reach the surface on Venus than on Earth.

Explanation:

When an object is dropped from a height on Venus, it will take longer to reach the surface compared to dropping the same object from the same height on Earth. This is because the acceleration due to gravity on Venus is smaller than on Earth. Gravity on Venus is about 0.904 times the gravity on Earth.

To calculate the time taken to reach the surface on Venus, we can use the equation:

t = sqrt((2h) / g)

Where h is the height and g is the acceleration due to gravity.

Let's assume the acceleration due to gravity on Earth is 9.8 m/s^2 and the acceleration due to gravity on Venus is 0.904 times that value. Plugging in the values, we get:

time on Venus = sqrt((2 * 17) / (0.904 * 9.8))

Simplifying the equation, we find that it takes approximately 1.56 times longer for the object to reach the surface when dropped on Venus compared to Earth.

Explanation:

a) [tex]W_1 = 2332 J[/tex], [tex]W_2= 2332 J[/tex]

The work done by the student in each trial is equal to the gravitational potential energy gained by the student:

[tex]W=mg\Delta h[/tex]

where

m = 68 kg is the mass of the student

g = 9.8 m/s^2 is the acceleration of gravity

[tex]\Delta h[/tex] is the gain in height of the student

For the first student, [tex]\Delta h = 3.5 m[/tex], so the work done is

[tex]W_1 = (68)(9.8)(3.5)=2332 J[/tex]

The second student runs up to the same height (3.5 m), so the work done by the second student is the same:

[tex]W_2 = (68)(9.8)(3.5)=2332 J[/tex]

2) [tex]P_1 = 204.6 W[/tex], [tex]P_2 = 274.4 W[/tex]

The power exerted by each student is given by

[tex]P=\frac{W}{t}[/tex]

where

W is the work done

t is the time taken

For the first student, [tex]W_1 = 2332 J[/tex] and [tex]t=11.4 s[/tex], so the power exerted is

[tex]P_1 = \frac{W_1}{t_1}=\frac{2332 J}{11.4 s}=204.6 W[/tex]

For the second student, [tex]W_2 = 2332 J[/tex] and [tex]t=8.5 s[/tex], so the power exerted is

[tex]P_2 = \frac{W_2}{t_2}=\frac{2332 J}{8.5 s}=274.4 W[/tex]

Among the options listed, skin color and eye shape are known to be dependent on a group of genes, making them polygenic traits. The others are believed to be influenced mainly by single genes, although this view is evolving.

The human variations that are dependent on a group of genes, also known as polygenic traits, include skin color, eye shape, and potentially, other physical attributes. This means that these traits are not determined by a single gene but by the interactions of multiple genes.

Skin color, eye shape are complex traits that are determined by the interaction of several genes. For instance, in the case of skin color, about 20 genes have been associated with variations in skin color.

The other two variations, cleft chin and attached earlobes, are traditionally thought of as being controlled by a single gene each, although recent research suggests a more complex genetic basis as well.

Hello There!

As you already know, magnetism is invisible. Magnetism comes from minerals that are found in the Earth. The earth has so many minerals so our planet is basically a giant magnet. The most common mineral that can be made into a magnet is Iron.

The Moon phase described is the waxing gibbous phase, which occurs after the first quarter phase and before a full moon, with the majority of the illuminated side becoming increasingly visible.

The phase of the Moon depicted in the description corresponds to the waxing gibbous phase.

This phase occurs during the week after the first quarter phase, where more of the Moon's illuminated half becomes visible from Earth, leading up to a full moon.

At the waxing gibbous phase, the Moon has not yet reached the full moon stage where it is opposite the Sun and its entire illuminated side is visible from Earth.

The waxing gibbous Moon rises in the afternoon and is visible for most of the night, setting in the early morning hours.

Its visibility throughout the night can be particularly helpful for activities like taking a romantic stroll or returning from a late-night study session.

(80kg)(3m/s)+(90)(-2m/s)=60N*s

Answer:

Total momentum of the system before the collision is 60 kg-m/s.

Explanation:

Given that,

Mass of Matt, m = 80 kg

Mass of Trey, m' = 90 kg

Initial speed of the Matt before the collision, u = 3 m/s (east)  

Initial speed of the Trey before the collision, u = -2 m/s (west)  

After the collision, Matt is moving 1.5 m/s to the west.

We need to find the total momentum of the system before the collision. We know that the momentum is given by the product of mass and velocity. Initial momentum is given by :

[tex]p_i=mu+m'u'\\\\p_i=80\times 3+90\times (-2)\\\\p_i=60\ kg-m/s[/tex]

So, the total momentum of the system before the collision is 60 kg-m/s. Hence, this is the required solution.
