Answer: The particle model, because only high-energy frequencies of lights can remove electrons.
Explanation: just did the test and got it right :)
Answer: Resonance
Explanation:
Resonance is a vibration set up in a body (house windows) due to a transfer of energy from another body (loud bass speaker) which is vibrating with a same or nearly equal frequency as that of the first.
Thus, resonance explains that once the natural frequency of the windows happens to be the same as the frequency of the speaker, vibrations occurs.
given that initial velocity is
deceleration is given as
now we have to find the distance covered in 16 s
so it will cover 137.6 m distance
part b)
in order to find the final speed
so its speed will be 6.2 m/s
Answer:
6 beats
If one fork beats once and another twice in the same time period
you would hear 1 beat. (Same for 2 and 3 beats).
