Answer:

Explanation:
Given that

re= 46 cm
Vp= 180 m/s
We know that


So

Now by putting the all given values in the questions


So the average electric field is
.
A water wheel is a machine for converting the energy of
Answer:
1. The Speed is 390
2. The Frequency is 425 Hz
3. The Wavelength is 1.3
Explanation:
1. To find the speed of a wave you have to do the formula of speed.
Speed = Wavelength x Wave Frequency.
Speed = 1.5 * 260
= 390
2.
Formula
F= 
F = 340 / 0.8
= 425
3.
Formula
Wavelength = speed / frequency
Wavelength = 440 / 344 (rounded to nearest tenth if necessary)
= 1.3
Hydrogen does not contain any neutrons
