The electromagnetic spectrum is divided into seven different frequency ranges which are from lowest to highest, radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
The electromagnetic spectrum includes electromagnetic waves with frequencies between one hertz and above 10²⁵ hertz, or wavelengths between thousands of kilometres and a small portion of the size of an atomic nucleus. The electromagnetic waves found within each of these bands are referred to by a different name. Starting at the low frequency(long wavelength), end of the spectrum, these are radio waves, micro waves, infrared, visible light, ultraviolet, x-rays and gamma rays. This frequency range is divided into separate bands.

What is that supposed to mean?
Answer: Tom drove 60 km/hr fast
Speed = Distance traveled / time taken
Explanation:
Given that:
Distance traveled by Tom = 60 km
Time taken by Tom = 1 hour
Speed = ?
Since speed is obtained by dividing distance traveled by the time taken, hence the formula to use is as follows:
speed = distance / time
Speed = 60 km / 1 hour
Speed = 60 km/hr
Thus, Tom had been driving 60 km/hr fast, using the formula "speed = distance / time"
Answer:
0J
Explanation:
The kinetic energy would be zero. An object just released from rest will have no kinetic energy but the potential energy will be maximum.
Kinetic energy is the energy due to the motion of a body
Potential energy is the energy due to the position of a body.
- The kinetic energy at the start will therefore be zero
- All the energy is stored as potential energy.
Therefore, the kinetic energy is zero
