The answer would be: <span>b. interactions between the atmosphere and geosphere during a drought
The experiment is clearly demonstrating what happens in drought. The soil that is put into direct sunlight without getting any water. The heat from the sunlight will be absorbed by the soil, makes the water content of the soil evaporates into the air. Since you don't give any water, the soil will be dry and start to crack.
The soil should represent the geosphere. The air represents the atmosphere.

The velocity of the submarine immediately after firing the missile is 0.0104 m/s
Explanation:
Mass of the submarine M=50 tonne=
Mass of the missile m=40 kg
velocity of the missile v= 13m/s
we have to calculate the velocity of the submarine after firing
This is the recoil velocity and its expression is derived from the law of conservation of momentum
recoil velocity of the submarine
In this case W is negative, the heat input is less than in the constant volume case, and CP is less than CV. If the ice melts it is as if it were being compressed because its volume is reduced.

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.
