Answer:
option A
Explanation:
renewable resources are replenishable that means they can't be depleted
The sound gets louder, like hitting a metal pole on a thin metal beam, the energy increases as the sound does.
Answer:
Velocity, v = 0.164 m/s
Explanation:
We have,
Frequency of wave, f = 0.04 Hz
Wavelength, 
It is required to find the velocity of a water wave. The speed of any wave is given in terms of wavelength and frequency. Its formula is :

So, the velocity of a water wave is 0.164 m/s.
D, all of these are voltage sources. A battery can power small things, generators can power larger things, and outlets can charge, or power things.
External = R
Internal = r
Volume of hemisperical = 2/3 π(R³-r³)
V= 2/3 π(9.1³ - 8.4³)
V= 336.9 cm³
