Answer:  option 3

The heat energy from the coffee is transferred to the mug. This is because of entropy change. For a certain time period the coffee release the heat to the adjacent walls of the mug. But after certain period of time both the mug and coffee reaches to the same temperature i.e., they become under equilibrium state.

And also over the time period the heat may also transfers to the surroundings and the mug will cool down and matches to the surrounding temperature.

Answer: Thermal energy from the coffee is transferred to the mug.

Explanation:

Heat loss will occur due to convection radiation and conduction

The mug gains heat from the coffee by conduction

Imagine that two balls, a basketball and a much larger exercise ball, are dropped from a parking garage. If both the mass and ra
pashok25 [27]

Here if we assume that there is no air friction on both balls then we can say

F = mg

now the acceleration is given as

F = ma = mg

a = g

so here both the balls will have same acceleration irrespective of size and mass

so we can say that to find out the time of fall of ball we can use

y = \frac{1}{2}gt^2

t = \sqrt{\frac{2y}{g}}

now from above equation we can say that time taken to hit the ground will be same for both balls and it is irrespective of its mass and size
