Answer:
Explanation:
Given the absence of non-conservative force, the motion of the coin is modelled after the Principle of Energy Conservation solely.
The moment of inertia of the coin is:
After some algebraic handling, an expression for the maximum vertical height is derived:
The amount of heat transferred from the ocean to the atmosphere as latent heat than sensible heat will be 10 times as much.
Latent heat and sensible heat are defined as follows:
- Latent heat: It is the heat that leaves/enters a system during a process where the temperature of the system stays constant.
Examples are phase changes where the latent heat from the system leaves (exothermic) or enters a system (endothermic).
- Sensible heat: It is the heat that enters or exits a system when the temperature of the system is not constant. The entire heat flows through the two systems and in order to do so it requires a temperature difference between the systems.
Thus, the amount of heat transferred from the ocean to the atmosphere as latent heat than sensible heat will be 10 times as much.

Answer:
They all hit at the same time
Explanation:
Let the time of flight is T.
The maximum height is H and the horizontal range is R.
The formula for the time of flight is
..... (1)
Te formula for the maximum height is
.... (2)
From equation (1) and (2), we get
here, we observe that the time of flight depends on the maximum height and according to the question, the maximum height for all the three balls is same so the time of flight of all the three balls is also same.
Because it is acted upon by balanced forces.
Toy cars use a variety of mechanisms to make them go, but they all store up potential energy. Although the elastic material inside is usually steel and not rubber, the principle is the same. By changing the shape of the material (usually a coil of metal) energy is stored and then released as motion.
