Answer:
C
Explanation:
Rocks with hotter temperatures sank to the bottom of the Earth. The rocks with the hottest temperature became the core and the rocks with the least amount of heat became the crust.
Hope this helps!
Answer:
The decrease of these factors increases the acceleration.
Explanation:
Hi, the decrease of these factors increases the acceleration.
Air resistance is a force opposing the acceleration. So if it decreases, the acceleration increases, because the opposite forces decreases.
The same is applied to the force of gravity, since the rocket travels upward; gravity is also an opposite force.
Finally, if the mass decreases, it means that the rocket becomes lighter and the force acting on the smaller mass causes an increase in the acceleration.
I am not as sure but I think it is 9.469 miles
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.
