Nico vibrates an object at different frequencies. At a certain frequency, the sound gets louder and then returns to the same volume when he moves to the next frequency. What is occurring when the sound gets louder?

The natural frequency of the object is changing.
The amplitude of the wave is doubling.
A standing wave is being generated.
Pitch is producing the louder sound.

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
