Answer:
a)speed of light.
a)speed of light×time=distance.
Explanation:
light has a constant speed of 299,792,458m/s
It would be potiental because your not moving
Answer:
friction reduces the efficiency of machines, thus we must reduce the friction force that is acting upon it.
Answer:
Electromagnetic
Explanation:
Electromagnetic waves are those waves that do not require any material medium for propagation. They arise from a vibration of electric and magnetic fields.
The electromagnetic spectrum is comprised of many waves. One of the waves in the spectrum is visible light.
Visible light is in turn composed of seven different wavelengths of which green light is one of them. Hence, green light travels by electromagetic wave.
Answer:
Explanation:
Given
In R-L-C circuit frequency is very high
Inductive Reactance for inductor is given by 
Inductive Reactance for Capacitor is given by 
as frequency becomes too high then 
will become very large and and 
will be approximately zero .
In other words inductor behave as a very high resistance and Capacitor behaves as very small resistance
