Answer and Explanation:
The rate (in W) at which heat energy moves from the more blazing article to the colder item increments with the temperature distinction between the items.
The more noteworthy the temperature contrast, the more prominent the rate at which exchange of heat energy takes place.
Thus the temperature difference between the beakers relates in the same manner as described above.
The exchange of heat energy continues until a thermal equilibrium is attained.
Answer:
D) 30.6J
Explanation:
Because:
gravitational potential energy=mass×gravitational field strength×height
1.3kg×9.8m/2squared×2.4m
= 30.6J
The answer is C -
because reversibility means when taking a break it'll be hard to get back on schedule

The people in the ship will see light travelling toward them at speed of light.
<u>Explanation:</u>
As the spaceship is moving away from the space station with one half speed of light. The light travelling from the space station with velocity c which is also termed as speed of light will be moving relative to the people in spaceship. So the relative velocities can be found as
In this case, u’ is the speed of light seen by the people in spaceship and u is the velocity of light while v is the velocity of moving spaceship.So u =c and v = . Then
Thus, the light travelling towards the people in the ship will view that light with the speed of light itself.
