Answer:

A horizontal line means the object is not changing its position - it is not moving, it is at rest. • A downward sloping line means the object is returning to the start. SPEED-TIME GRAPHS. Speed-Time graphs are also called Velocity Time graphs.

Explanation:

Answer: The object is moving in a constant speed.

Explanation: In a distance time graph a horizontal line indicates a zero slope which means the object maintains a constant speed in motion. Rising slope an increase in speed and a slope going down indicates a decrease in speed.

Answer: 450 kg

Explanation: p=mv

m= p/v

m=40500/90

m=450kg

The mass of the truck given that it has a momentum of 40500 Kgm/s and moving at 90 m/s is 450 Kg

Momentum is defined as the product of mass and velocity. It is expressed as

Momentum = mass × velocity

Momentum = mass × velocity

40500 = mass × 90

Divide both side by 90

Mass = 40500 / 90

Mass = 450 Kg

No, the speed at which an object falls is not equal to the acceleration at which it falls.

Answer:

Option B

Explanation:

Speed is defined as how fast an object can cover a specific distance and in what time it covers. So it is measured as the ratio of distance covered to the time taken to cover that distance. While acceleration is the rate of change of velocity. Moreover, speed is a scalar quantity and acceleration is a vector quantity. So most of the times, the direction will play an important role in the varying values of speed and acceleration. Also, acceleration of an object will depend upon the force and mass of the object. Thus, speed and acceleration will not attain same value always.

Answer:

1500 m/s

Explanation:

The sound wave travels 750 meters from the ship to the bottom of the water, then 750 meters back to the ship.  So it travels a total distance of 1500 meters in 1 second.

So the average speed is:

v = 1500 m / 1 s

v = 1500 m/s

Answer: 12000 kg m/s

Explanation:

According to the Impulse-Momentum Theorem, we have:

[tex]F \Delta t= \Delta p[/tex]

Where:

[tex]F=3000 N[/tex] is the exerted force

[tex]\Delta t=4 s[/tex] is the time interval

[tex] \Delta p[/tex] is the change in momentum or impulse

Then:

[tex](3000 N)(4 s)= \Delta p[/tex]

[tex]\Delta p=12000 kg m/s[/tex]  This is the impulse impacted on the object

a) Distance moved by the top lid during a blink: 1 cm (estimate)

b) The acceleration is [tex]34.7 m/s^2[/tex]

c) The final speed is 0.83 m/s

Explanation:

a)

For the purpose of this problem, we can estimate the size of the eye from the top lid to the bottom lid to be 1 cm, so this is the distance moved by the top lid during a blink.

b)

Assuming the motion of the eyelid to be at constant acceleration, we can find the acceleration by using the following suvat equation:

[tex]s=ut+\frac{1}{2}at^2[/tex]

where

s is the distance covered

u is the initial velocity

t is the time

a is the acceleration

For the eyelid, we have:

u = 0 (it starts from rest)

s = 1 cm = 0.01 m is the distance covered

t = 0.024 s is the time taken

Solving for a, we find the acceleration:

[tex]a=\frac{2s}{t^2}=\frac{2(0.01)}{0.024^2}=34.7 m/s^2[/tex]

c)

The final speed of the upper eyelid can be found by using another suvat equation:

[tex]v=u+at[/tex]

where

v is the final speed

u is the initial speed

a is the acceleration

t is the time

For the eyelid in this problem, we have

u = 0

[tex]a=34.7 m/s^2[/tex]

t = 0.024 s

Substituting, we find the final speed:

[tex]v=0+(34.7)(0.024)=0.83 m/s[/tex]

The horizontal range of the missile is b) 176 m

Explanation:

The motion of the missile is a projectile motion, so it consists of two independent motions:  

- A uniform motion with constant velocity along the horizontal direction  

- A uniformly accelerated motion with constant acceleration (equal to the acceleration of gravity) in the vertical-downward direction  

To find the time of flight of the missile, we study the vertical motion. We can use the following suvat equation:

[tex]s=u_y t+\frac{1}{2}at^2[/tex]

where:

s = 75 m is the vertical displacement of the missile (the height of the building)

[tex]u_y=0[/tex] is the initial vertical velocity  (the missile is thrown horizontally)

t is the time of flight

[tex]a=g=9.8 m/s^2[/tex] is the acceleration of gravity

Solving for t, we find the time of flight:

[tex]t=\sqrt{\frac{2s}{g}}=\sqrt{\frac{2(75)}{9.8}}=3.91 s[/tex]

This means that the missile takes 3.91 s to reach the ground.

Now we study the horizontal motion: the missile moves with a constant horizontal velocity of

[tex]v_x = 45 m/s[/tex]

Therefore, the distance covered in a time t is

[tex]d=v_x t[/tex]

and by substituting t = 3.91 s, we find the horizontal range of the missile:

[tex]d=(45)(3.91)=176 m[/tex]

A) Acceleration in part A: [tex]6.1 m/s^2[/tex]

B) Acceleration in part B: [tex]2.7 m/s^2[/tex]

C) Acceleration in part C: [tex]1.5 m/s^2[/tex]

Explanation:

A)

The picture of the problem is missing: find it in attachment.

The acceleration of a body is equal to the rate of change of its velocity:

[tex]a=\frac{v-u}{\Delta t}[/tex]

where

v is the final velocity

u is the initial velocity

[tex]\Delta t[/tex] is the time it takes for the velocity to change from u to v

In part A of the race, we have:

u = 0

v = 5.5 m/s (estimate)

[tex]\Delta t = 0.9 - 0 = 0.9 s[/tex]

So the acceleration is

[tex]a=\frac{5.5-0}{0.9}=6.1 m/s^2[/tex]

B)

In part B of the race, we have:

u = 5.5 m/s is the initial velocity (estimate)

v = 9.5 m/s is the final velocity (estimate)

[tex]\Delta t = 2.4 - 0.9 = 1.5 s[/tex] is the time interval between the two points considered

Therefore, using the equation for the acceleration, we can find the acceleration in part B:

[tex]a=\frac{9.5-5.5}{1.5}=2.7 m/s^2[/tex]

C)

In part C of the race, we have:

u = 9.5 m/s is the initial velocity (estimate)

v = 11 m/s is the final velocity (estimate)

[tex]\Delta t = 3.4 - 2.4 = 1 s[/tex] is the time interval between the two points considered

And therefore, the acceleration in part C of the race is:

[tex]a=\frac{11-9.5}{1}=1.5 m/s^2[/tex]

Answer:

1.8 L

Explanation:

Ideal gas law:

PV = nRT

where P is absolute pressure,

V is volume,

n is number of moles,

R is the gas constant,

and T is absolute temperature.

Rearranging:

V / T = nR / P

Since n, R, and P are constant:

V₁ / T₁ = V₂ / T₂

1.5 L / (298.15 K) = V / (363.15 K)

V = 1.8 L

Charles's Law is used to find the new volume of a balloon when heated from 25°C to 90°C. Converting these temperatures to Kelvin and solving gives a new volume of 1.83 L.

The question involves understanding how the volume of a gas changes with temperature, governed by Charles's Law, which states that the volume of a gas at constant pressure is directly proportional to its temperature in Kelvin. To find the new volume of a balloon when its temperature is increased from 25°C to 90°C, we first convert these temperatures to Kelvin (°K) because the gas law uses absolute temperatures. The formula to convert Celsius to Kelvin is K = °C + 273.15. Thus, the original temperature is 298.15 K (25 + 273.15), and the new temperature is 363.15 K (90 + 273.15).

Using Charles's Law (V1/T1 = V2/T2), where V1 is the original volume (1.5 L), T1 is the original temperature (298.15 K), V2 is the final volume, and T2 is the final temperature (363.15 K), we can solve for V2. Rearranging the formula gives us V2 = V1 * (T2/T1).

Substituting the given values, V2 = 1.5 L * (363.15 K / 298.15 K) = 1.5 L * (1.218) = 1.83 L. Therefore, the volume of the balloon when placed in a container of hot water at 90°C would be 1.83 L.

So, if an object travels in a curved path, it changes velocity, and, thus, accelerates. This acceleration must be tied to a force. ... Therefore, whenever an object travels in a curved path, there must be an unbalanced force acting upon it. It is important to understand that all this may occur without a change in speed.t

The velocity of the ball is zero at the point of release.

Thus the ball have the least kinetic energy just after it is released.

The energy of the object due to its motion is known as the kinetic energy of that object.

As the ball has some height before it is dropped.

Due to this height the ball posse some potential energy which is equal to the product of its mass, height and the gravitational force.Here kinetic energy is zero.

Liquids and gases are a part of fluids.

Explanation

Liquids and gases are two states of matter and they differ from solids in terms of close packing of the particles and freedom of movement. The solid particles are closely packed allowing lesser freedom  of movement while the particles are not the tightly packed in liquids and gases. gases have greater freedom of movement than solids and liquids and liquids have greater freedom of movement than solids.

Due to this factor liquids and gases can  move or flow easily and that is why they are called fluids.

Law of conservation of energy

It states that energy can be converted from one form to another but total energy of the system remains same .

That is why : in above asked question ,when body is moving it has kinetic energy , when stops the kinetic energy gets converted to potential energy , but the total energy of system remains same .

The object's kinetic energy would decrease, its potential energy would increase, and its total mechanical energy would remain the same.

The total mechanical energy (E) of a system is the sum of its kinetic energy (KE) and its potential energy (PE).

E = KE+ PE

conservation of energy:

whenever an object is acted upon by a non-dissipative conservative force its total mechanical energy remains conserved.

So, when the object slows down, its velocity decreases, and therefore its kinetic energy decreases. Since the total mechanical energy remains conserved, the loss in kinetic energy is converted into gain in potential energy, and the potential energy increases.

The incorrect statement about the nuclear strong force is that it is responsible for the sun's nuclear fission reactions. In reality, the strong force is crucial for binding nucleons within nuclei and operates over extremely short distances, but it is not responsible for fission in the sun.

Explanation:

The statement about the nuclear strong force that is not true is: The nuclear strong force is responsible for the sun’s nuclear fission reactions. This is incorrect because the strong force is not responsible for fission in the sun; instead, it plays a crucial role in maintaining the stability of atomic nuclei by binding protons and neutrons together. It is a powerful attractive force that acts over extremely short distances, approximately 10-15 meters, and is much stronger than electrostatic repulsions between similarly charged protons. However, its primary role is not in driving the sun's fission reactions, but in the fusion processes that occur in stars, including our sun.

This umbrella-subject is typically designed for physics students and functions to provide a general introduction to each of three core heat-related subjects. Other authors, however, define thermal physics loosely as a summation of only thermodynamics and statistical mechanics.

Explanation:

Final answer:

Thermal physics is a branch of physics focused on energy transfer and the behavior of particles in relation to heat, including study areas like thermochemistry and thermodynamics. It encompasses thermal agitation, heat transfer, and laws of energy conservation.

Explanation:

Thermal physics is an area of physics that deals with the energy transfer, thermal properties of materials, and the behavior of particles related to heat. It encompasses topics such as thermochemistry, the laws of thermodynamics, and thermal agitation. Thermal agitation refers to the random motion of atoms and molecules in any object with a temperature above absolute zero, resulting in the emission and absorption of radiation. In essence, thermal physics explores how thermal energy, or the kinetic energy of particles, flows and changes within systems. Thermal energy is a form of kinetic energy at the microscopic scale, crucial in understanding heat transfer, and how it influences work and energy conservation.

At the macroscopic level, thermal physics analyzes how heat transfer affects the internal energy of systems, aligning with Big Ideas from the AP Physics Curriculum Framework. Heat transfer describes energy movement from a hotter object to a cooler one, leading to temperature variations and potential work, exemplified by heat engines. Fundamental laws of physics, including the law of conservation of energy, govern these thermal interactions and their efficiencies.

Answer:

1.53 m/s

Explanation:

Given:

Mass of the car (M) = 1300 kg

Mass of the coal (m) = 400 kg

Initial velocity of the car (U) = 2 m/s

Initial velocity of the coal (u) = 0 m/s (Since it is dropped)

When the coal is dropped into the car, then they move with same final velocity.

Let the final velocity be 'v' m/s.

For a closed system, the law of conservation of momentum holds true.

So, initial momentum is equal to final momentum of the car-coal system.

Initial momentum of the car = [tex]MU=1300\times 2=2600\ Ns[/tex]

Initial momentum of the coal = [tex]mu=0\ Ns[/tex]

Total initial momentum is the sum of the above two momentums.

So, total initial momentum = 2600 + 0 = 2600 Ns

Now, final momentum is given as the product of combined mass and final velocity. So,

Final momentum of the system = [tex](M+m)v=(1300+400)v=1700v[/tex]

Now, from law of conservation of momentum,

Initial momentum = Final momentum

[tex]2600=1700v\\\\v=\frac{2600}{1700}\\\\v=1.53\ m/s[/tex]

Therefore, the final velocity of either of the two masses is same is equal to 1.53 m/s.

To find the final velocity of the car after the coal is dropped, we can use the principle of conservation of momentum.

To solve this problem, we can use the principle of conservation of momentum. The momentum before the coal is dropped vertically into the car is given by the product of the mass and velocity of the car, which is 1,300 kg×2.0 m/s = 2,600 kg×m/s. After the coal is dropped, the total momentum of the system should remain the same since there is no external force acting on it. Therefore, the final velocity of the car can be calculated by dividing the total momentum by the new total mass of the car and coal, which is 1,300 kg + 400 kg = 1,700 kg.

Using the equation:

(initial momentum) = (final momentum)

(1,300 kg × 2.0 m/s) = (1,700 kg × v)

Solving for v, we find that the final velocity of the car after the coal is dropped is approximately 1.529 m/s.
