Answer:
the portion of electromagnetic spectrum is occupied by signal is called bandwidth
Explanation:
Bandwidth is the part of electromagnetic spectrum which is occupied by the signal. It is also called as the range of frequency over which the receiver or any other electronic circuit works. Bandwidth is the amount of the data been transmitted from one point to other within the network in the specific amount of the time. It is expressed as the bit rate and are measured as bits per seconds (bps). Bandwidth is the sum of the connections.
The Speed of Light.
Photons emitted from the surface of the sun to travel across the vacuum of space to reach out eyes
Answer:
Linear and rotational Kinetic Energy + Gravitational potential energy
Explanation:
The ball rolls off a tall roof and starts falling.
Let us first consider the potential energy or more specifically gravitational potential energy (
; 
= mass of the ball, 
= acceleration due to gravity, 
= height of the roof). This energy comes because someone or something had to do work to take the ball to the top of the roof against the force of gravity. The potential energy is naturally maximum at the top and minimum when the ball finally reaches the ground.
Now, the ball starts to roll and falls off the roof. It shall continue rotating because of inertia (Newton's first law). This contributes to the rotational kinetic energy (
; 
=moment of inertia of the ball & 
= angular velocity).
Finally comes the linear kinetic energy or simply, kinetic energy (
) which is caused due to the velocity 
of the ball.
