Answer:
The tension of the string is 41.876 N
Explanation:
Given;
length of the string, L = 2.11 m
mass of the string, m = 19.5 g = 0.0195 kg
frequency of the wave, f = 440 Hz
wavelength, λ = 15.3 cm = 0.153 m
The velocity of the wave is given by;
v = fλ
v = 440 x 0.153
v = 67.32 m/s
Also the velocity of the wave is given by
where;
μ is mass per unit length = 0.0195 / 2.11 = 0.00924 kg/m
T is the tension of the string
T = v²μ
T = (67.32)²(0.00924)
T = 41.876 N
Therefore, the tension of the string is 41.876 N

Explanation:
True
Answer:
The Sun-Earth-Moon system happens to exhibit a striking geometric coincidence, which we examine in the first problem. PROBLEM 1. To an observer on Earth, the Sun and the Moon subtend almost the same angle in the sky. The average angle is 0.52 degrees for the Moon and 0.53 degrees for the Sun.
Answer:
The mass is 
Explanation:
From the question we are told that
The speed of the charge is 
The magnetic field is 
The radius is 
The value of the charge is 
The centripetal acting on the charge moving in the circular orbit is mathematically represented as
Now this centripetal force is due to the force exerted on the charge by the magnetic field on the charge which is mathematically represented as
At the maximum of this magnetic force 
So
Now given that it is this magnetic force that is causing the circular motion we have that
=> 
=> 
substituting values
