Ranking Task: The Electromagnetic Spectrum
shutvik [7]

The increasing order of the wavelength from left to right are as follows Gamma Rays <  X-rays < UV rays < visible rays < infrared rays < microwaves < radio waves.

The electromagnetic spectrum consists of many waves which are made up of electric field and the magnetic field.

It is said that the electromagnetic wave behaves like particle as well as the wave.

The particle like pieces of the wave are called photons which contains the energy of the wave and the electromagnetic waves are primarily decided by the wavelength and the frequency of the wave.

The group of electromagnetic waves are known as electromagnetic spectrum.

The electromagnetic wave in the order of increasing wavelength are Gamma Rays <  X-rays < UV rays < visible rays < infrared rays < microwaves < radio waves.

A ferris wheel with radius 12 m makes a revolution every 3 minutes. Find the linear (tangental) speed of a passenger. How far do
Alina [70]

Answer:

The linear (tangential) speed of a passenger is 0.4188 m/s

The distance traveled by the person in 5 minutes ride is 125.64 m

Explanation:

Given;

radius of the Ferris, r = 12 m

1 revolution per 3 minutes, \omega = \frac{2\pi (radian)}{3\ (minutes)} *\frac{1\ minute}{60 \ seconds} = 0.0349 \ rad/s

The linear (tangential) speed of a passenger is given by;

v = ωr

v = (0.0349)(12)

v = 0.4188 m/s

The distance traveled by the person in 5 minutes ride is given by;

d = vt

d = (0.4188)(5 x 60)

d = 125.64 m
