What is the amount of space that a gas takes up called?
ASAP 20 points???
Answer:
Mass is the amount of matter an object has, and volume is the amount of space the matter takes up. Solids are easy to recognize. They have definite shape, mass, and volume. Trees are solids.
Explanation:
The amount of space occupied by a gas is called volume of the gas. The volume of a gas depends on the temperature and pressure.
What is volume ?Volume is a physical parameter describing the space occupied by a substance. Volume is an extensive property. Therefore, volume is dependent upon amount of the substance.
The total amount of a substance is called its mass. Density describes how closely its particles are packed in a given volume. Hence, volume is the ratio of mass to the density.
Volume of a gas changes with its temperature and pressure. As the pressure increases, volume increases whereas, as the temperature increase, volume increases.

a snowball thrown at an ice cream truck at Valley Forge in January sticks to the side. Into what form of energy was the mechanical energy changed
Answer:
Thermal Energy
Explanation:
I majored in Physics
When a snowball thrown at an ice cream truck at Valley Forge in January sticks to the side, the mechanical energy was changed into thermal energy.
What is law of conservation of energy?
Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present.
The law of energy conservation is adhered to by all energy forms. The law of conservation of energy essentially says that all energy is conserved in closed systems, or systems that are isolated from their surroundings.
When a snowball thrown at an ice cream truck at Valley Forge in January, the mechanical energy was changed into thermal energy and the edges of the ice melts and again due to temperature of the surrounding they freezes together and the snowball sticks to the side.

A billiard ball moving at 5 m/s strikes another ball which is initially at rest. After the collision, the first ball moves at a velocity of 4.35 m/s at an angle of 30o below its original motion. Find the velocity and angle of the second ball after the collision. Assume that the collision is perfectly elastic.
Answer:
The velocity of the second ball is approximately 2.588 m/s
The angle direction of the second ball is 75° counterclockwise from the horizontal
Explanation:
The initial velocity of the first billiard ball = 5 m/s
The initial velocity of the billiard ball the first billiard ball strikes = 0 m/s
The final velocity of the first billiard ball = 4.35 m/s
The final direction of motion of the first billiard ball = 30° below its original motion
For perfectly elastic collision, whereby the target is at rest initially, by conservation of momentum, we have;
m₁ × [tex]\underset{v_1}{\rightarrow}[/tex] = m₁·[tex]\underset{v'_1}{\rightarrow}[/tex] + m₂·[tex]\underset{v'_2}{\rightarrow}[/tex]
Which gives;
m₁ × 5·i = m₁·((√3)/2×5·i - 2.5·j) + m₂·[tex]\underset{v'_2}{\rightarrow}[/tex]
∴ m₂·[tex]\underset{v'_2}{\rightarrow}[/tex] = m₁ × 5·i - m₁·((√3)/2×5·i - 2.5·j)
m₂·[tex]\underset{v'_2}{\rightarrow}[/tex] = m₁ × 5·(1 - √3/2)·i + m₁·2.5·j = m₁ × 2.5·(2 - √3)·i + m₁·2.5·j
Therefore, given that the mass of both billiard balls are equal, we have, m₁ = m₂, which gives;
m₂·[tex]\underset{v'_2}{\rightarrow}[/tex] = m₁·[tex]\underset{v'_2}{\rightarrow}[/tex] = m₁ × 2.5·(2 - √3)·i + m₁·2.5·j
∴ [tex]\underset{v'_2}{\rightarrow}[/tex] = 2.5·(2 - √3)·i + 2.5·j
The magnitude of the velocity of the second ball is [tex]\underset{v'_2}{\rightarrow}[/tex] = √((2.5·(2 - √3))² + 2.5²) ≈ 2.588 m/s
The direction of the second ball, θ = arctan(2.5/((2.5·(2 - √3))) = 75° counterclockwise from the horizontal.

A shopper in a supermarket pushes a cart with a force of 35 N directed parallel to the ground. Find the work done by the shopper on the cart as the shopper moves along a 50.0 m length of aisle.
Answer:
W = 1750 N
Explanation:
Given that,
A shopper in a supermarket pushes a cart with a force of 35 N directed parallel to the ground.
We need to find the work done by the shopper on the cart as the shopper moves along a 50.0 m length.
Let W is the work done. As the force is parallel to the ground, angle between force and distance is 0 degrees.
W = Fd
W = 35 N × 50 m
= 1750 N
So, the work done by the shopper on the cart is 1750 N.

A 5-kg object is sliding to the right and encountering a friction force that slows it down. The coefficient of friction (μ) between the object and the surface is 0.1. What is the acceleration of the object? Note: There is no applied force here.
Answer:
The friction force is 4.9 N
[tex]a = 0.98\ m/s^2[/tex]
Explanation:
Friction Force
When an object is moving and encounters friction in the air or rough surfaces, it loses acceleration or speed because the friction force opposes motion.
The friction force when an object moves on a horizontal surface is calculated by:
[tex]Fr=\mu N[/tex]
Where [tex]\mu[/tex] is the coefficient of static or kinetics friction and N is the normal force.
If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal are equal in magnitude:
N = W = m.g
Thus, the friction force is:
[tex]Fr=\mu W[/tex]
The object has a mass of m=5 Kg, calculate the weight:
W = 5 * 9.8 = 49 N
It encounters a friction force that slows it down. We are given the coefficient of friction μ = 0.1, thus the friction force is:
Fr=0.1 49 N = 4.9 N
The friction force is 4.9 N
Since the only force acting on the object is the friction force, thus the net force is F = 4.9 N, and the acceleration can be calculated by using the equation of Newton's second law:
F = m.a
Solving for a:
[tex]\displaystyle a = \frac{F}{m}[/tex]
[tex]\displaystyle a = \frac{4.9}{5}[/tex]
[tex]\mathbf{a = 0.98\ m/s^2}[/tex]

The rate at which work is done is called power.
O A True
O B. False
I believe it’s true?
Answer: A) True, you are correct
==================================================
Explanation:
Power in physics is defined as
power = (change in work)/(change in time)
which shows that power is basically the rate of work done. We can think of it like a speed of sorts.
------------
For example, if you apply 100 joules of work over 2 seconds, then,
power = (100 joules)/(2 seconds)
power = (100/2) joules per second
power = 50 watts
A watt is defined to be a joule per second, and it's often used to measure how much electricity is consumed, but it has broader uses in physics as well.

If it requires E joules of energy to raise a mass from the surface of the Earth to an altitude of 6,000 km above the Earth, how much energy is required to raise it from the surface to an altitude of 12,000 km?
Answer:
To raise the mass to an altitude of 12,000 Km 2E joules are required.
Explanation:
Gravitational Potential Energy
It's the energy stored in an object because of its vertical position or height in a gravitational field.
It can be calculated with the equation:
U=m.g.h
Where:
m = mass of the object
h = height with respect to a fixed reference
g = acceleration of gravity, or [tex]9.8 m/s^2[/tex].
If a mass has a height h1, its potential energy is
[tex]U_1=m.g.h_1[/tex]
If a mass has a height h2, its potential energy is
[tex]U_2=m.g.h_2[/tex]
The ratio of both potential energies is:
[tex]\displaystyle \frac{U_2}{U_1}=\frac{m.g.h_2}{m.g.h_1}[/tex]
Simplifying:
[tex]\displaystyle \frac{U_2}{U_1}=\frac{h_2}{h_1}[/tex]
Solving for U2:
[tex]\displaystyle U_2=U_1.\frac{h_2}{h_1}[/tex]
Since U1=E:
[tex]\displaystyle U_2=E.\frac{12,000~Km}{6,000~Km}[/tex]
[tex]U_2 = 2E[/tex]
To raise the mass to an altitude of 12,000 Km 2E joules are required.
