In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized. So I believe D.
For an object to move its force must be greater than its mass for able for it to move. Let say you have a 10 kg box and a 50 kg box in the floor. you tried to push the 10 kg and its easier because force depends on its mass and your acceleration. Hope this helps
Answer:
the force exerted on the charge 10 q have a magnitude that is greater than F
Explanation:
The relation between the force and the charge are direct proportionality, it implies that as the charges is increasing the forces will be increasing too
Answer:
In order to make a sound wave have a higher pitch you increase the frequency.
In order to increase the volume of a sound wave, you have to increase the amplitude.
Hope this helps!

I want to say Liters but not 100% sure
