Friction can be reduced by making the surface smoother, lubricating the surface, or reducing the contact between the forces.
Hope this helps!
Answer:
a) The electric potential between the cylinders,
b) The electric field between the cylinders,
Explanation:
Voltage at the inner conductor, V₁ = 20 volts
Voltage at the outer conductor, V₂ = 100 volts
Change in potential,
The change in potential is given by the formula:
The electric field,
To get the electric potential at a certain point, L from the center:
The distance from the outer conductor to the center = b - L
The electric potential at L will be given by the equation:
Answer:
The frequency of the second wave is half of the frequency of first one.
Explanation:
The wavelength of the second wave is double is the first wave.
As we know that the frequency is inversely proportional to the wavelength of the velocity is same.
velocity = frequency x wavelength
So, the ratio of frequency of second wave to the first wave is
The frequency of the second wave is half of the frequency of first one.
