Answer:
0.23348 A
Explanation:
B = Magnetic field
v = Velocity of electron = 
q = Charge of electron = 
= Vacuum permeability = 
r = Radius of circle = 0.026 m
N = Number of turns = 103 turns/cm = 
I = Current
The magnetic and centripetal force will be balanced

The magnetic field in solenoid is given by

From the first equation

The current in the solenoid is 0.23348 A
Answer:
The phase difference is
Explanation:
From the question we are told that
The distance between the loudspeakers is 
The distance of the listener from the wall 
The frequency of the loudspeakers is 
The velocity of sound is 
The path difference of the sound wave that is getting to the listener is mathematically represented as

Substituting values


The phase difference is mathematically represented as
= 
Where
is the wavelength which is mathematically represented as

substituting value


Substituting value into the equation for phase difference
= 
Answer:
the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
Explanation:
You are correct it is translucent because opaque let’s no light through but transparent lets almost all light through
