Answer:
A. Heat flows from an object at higher temperature to an object at lower temperature
Explanation:
The option A obeys the 2nd law of thermodynamics. The heat will flow from the object at higher temperature to the object at Lower temperature till they reach an equilibrial state.
Heat doesn’t necessarily flow from an object with higher thermal energy to an object with lower thermal energy because an object has a higher thermal energy when it’s mass is more than the other. This makes B wrong.
C is wrong because heat moves from an object with higher temperature to objects with Lower temperature regardless of the state of matter.
Answer:
In physics, a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body. In its original concept, gravity was a force between point masses. Please give me the brainiest answer?
:) Hoped this helped!!! Have a good day!!! <3
They will both hit the ground at the same time due to gravity.
that means they took the same time to travel the distance to the ground
however, the ball traveled farther
speed=distance (or displacement) divided by time
so the greater the distance, the greater the speed
the ball traveled faster in the same time so it traveled faster
answer is ball
According to momentum conservation
15*3 = 45kgm/s
and the velocity of 5 kg mass will be
45/5 = 9 m/s
