Answer:
Microwaves, visible light, ultraviolet light, x-rays, γ-rays
Explanation:
The energy of any wave is given by :
h = Planck's constant
is the frequency of wave
It is clear that the energy of any wave is directly proportional to its frequency. Gamma rays have maximum frequency. Out of given options microwaves have least frequency.
So, the increasing order of energy is "microwaves, visible light, ultraviolet light, x-rays, γ-rays". Hence, the correct option is (5).
Given parameters:
Mass of object = 6.7kg
Velocity = 8m/s
Unknown parameter:
Kinetic energy = ?
Energy is defined as the ability to do work. There are two forms of energy;
Kinetic and potential energy.
Kinetic energy is the energy due to the motion of a body. Whereas, potential energy is the energy due to the position of a body usually at rest.
Kinetic energy is mathematically expressed as;
Kinetic energy =
where m is the mass of the body
v is the velocity of the body
Since we have been given both mass and velocity, input the parameter to solve for the unknown;
Kinetic energy = x 6.7 x 8² = 214.4J
So the kinetic energy of the body is 214.4J
