Hot air is less dense than cold air, causing it to displace and rise to the top.
A very long solenoid has a magnetic field inside which depends on the current in the wire and the number of turns per unit length of the solenoid. ... Adding more turns in the coil can also increase the total resistance of the wire.
The energy of the wave is D) 16.0 units squared
Explanation:
The energy of a wave is directly proportional to the square of the amplitude of the wave.
Mathematically, this can be written as
where
E is the energy of the wave
A is its amplitude
For the wave in this problem, the amplitude is
A = 4 units
Therefore, assuming that the constant of proportionality is 1, the energy of this wave is
units squared
