Answer:b
Explanation:
b temperature and pressure only
c. volume and temperature only
d. temperature, pressure, and volume
The combined gas law relates temperature, pressure, and volume and can be represented by the equation P1V1 / T1 = P2V2 / T2.
The combined gas law relates temperature, pressure, and volume. It states that the product of the initial pressure, volume, and temperature of a gas is equal to the product of the final pressure, volume, and temperature. This law can be represented by the equation:
P1V1 / T1 = P2V2 / T2
where P1 and P2 are the initial and final pressures, V1 and V2 are the initial and final volumes, and T1 and T2 are the initial and final temperatures.

The object with the larger mass will have greater damage.
B.
The object with the smaller mass will continue forward due to inertia.
C.
They will push away from each other in proportion to their masses.
D.
They will both make a sudden stop.
Impulse corresponds to the change in momentum. Given a soccer ball weighing 0.40kg moving first at 18m/s north and then hit in the opposite direction at 22m/s, the impulse delivered to the ball by the player is approximately 16 kg.m/s in the opposite direction of the initial movement.
In the field of physics, impulse is defined as the change in momentum of an object upon interaction with an external force and is calculated by multiplying the force applied to the object by the time interval (duration) the force was acting. When a soccer player strikes the ball, he or she applies a force that changes the soccer ball's momentum.
Considering your question about the soccer ball, the initial momentum of the ball can be calculated by multiplying its mass (0.40 kg) by its velocity (18 m/s), giving 7.2 kg.m/s north. When the player hits the ball, it moves in the opposite direction (south) with a velocity of 22 m/s. Thus, the final momentum of the ball is 0.40 kg x -22 m/s = -8.8 kg.m/s.
Impulse is the change in momentum, so it's the final momentum minus the initial momentum, which equates to -8.8 kg.m/s - 7.2 kg.m/s= -16 kg.m/s south or +16 kg.m/s north, depending on the coordinate system you choose (north could be either positive or negative). Since the direction reversed, this is why we have a negative sign.
