Answer:
Acceleration of the electron will be
Explanation:
We have given electric field 
Charge on electron 
So force in the electron 
Mass of electron 
Now according to newton second law
F = ma, here m is mass and a is acceleration
So 

So acceleration of the electron will be 
Answer:
a) 22.2 N
Explanation:
To find load effort. Identify load, efficiency and velocity ratio (VR)
Here given:
- VR (number of pulleys) = 6
Effort :

Answer:
2 cm and 6 cm.
Explanation:
The maximum displacement of first square wave pulse is 4 cm and the maximum displacement of second square wave pulse is 2 cm. We need to find a possible displacement of the string when the wave pules overlap.
It could be result in constructive interference or destructive interference.The possible displacement of the string are :
4 cm - 2 cm = 2 cm
4 cm + 2 cm = 6 cm
Hence, the correct options are (A) and (C).
The correct answer is letter A. star. <span>A ball of gas becomes a STAR when nuclear fusion begins in its core.</span>
1. The wavelength is the ratio of the wave's speed to its frequency in hertz or 1/s. This is shown below,
λ = s / f = (320 m/s) / (300 1/s) = 1.07 m
The wavelength is approximately 1.07 m.
2. The frequency is the ratio between speed and the wavelength,
f = (330 m/s) / 0.45 m = 733.33 hertz
