Answer:
maintaining internal balance
Explanation:
this question is in biology not physics
Impulse = Force * times and also Impulse = change in momentum.
Given that the mass does not change, change if momentum = mass * (final velocity - initial velocity)
Given that you know mass and initial velocity (which is the velicity before the cart hits the wall) you need the final velocity (which is the velocity after the cart hits the wall).
Answer: the velocity of the cart after it hits the wall.
Answer:
A
Explanation:
because the first law of thermodynamics is heat brings energy, but don't get confused with C, because bicyle pumps is the thing itself getting warm, though its not providing any energy unlike the stove, which uses it energy to heat something.
hope this helps :)
