Answer: rp/re= me/mp= 544 * 10^-6.
Explanation: To calculate this problem we have to consider the circular movement by the electron and proton inside a magnetic field.
Then the dynamic equation for the circular movement is given by:
Fcentripetal= m*ω^2.r
q*v*B=m*ω^2.r
we write this for each particle then we have the following:
q*v*B=me* ω^2*re
q*v*B=mp* ω^2*rp
rp/re=me/mp=9.1*10^-31/1.67*10^-27=544*10^-6
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
The rotational kinematics allows finding that the response for the time to reach the washing speed is
t = 4.26 s
Kinematics studies the motion of bodies, in the special case that the motion is circular is called rotational kinematics.
θ = w₀ t + ½ α t²
Where θ is the angle, w₀ are the initial angular velocity, α is the angular acceleration and t is the time
Rotational kinematics is written in units of radians, therefore all magnitudes must be reduced,
θ = 6 rev ( ) = 12π rad
In this case the washing machine starts from rest, therefore the initial rotational velocity is zero
θ = ½ α t²
t =
t =
t = 4.26 s
In conclusion using rotational kinematics we can find that the answer for the time to reach the washing speed is
t = 4.26 s

Frequency - 50Hz. Which means that the time period of the wave if 1/50 = 0.02 sec. Here we are going to check the average voltage for the time interval of 0.01sec. If the interval lies between π/2 to 3π/2. the average voltage will be zero. In all the other cases it will not be zero
