Answer: The object moved 2 metres away
Explanation:
Given that the
Force applied F = 20 N
Work done W = 40 J
From the definition of workdone which state that: product of force and distance
W.D = F × S
Where S = distance
S = W.D/F
S = 40/20 = 2 metres
The object moved 2 metres away.
Electromagnetic waves are produced by light. They are made up of oscillating magnetic and electric fields. They include radio waves, microwaves,infrared waves, visible light, ultraviolet, x-rays and gamma rays. Electromagnetic waves carry energy. radio waves are used in communications to send signals from one place to another.Microwaves use high energy that increases the motion of molecules in your food. Infrared waves are used in things like night vision cameras or a tv remote. The human body has a temperature that produces radiation which can be picked up by an infrareds device.Ultraviolet light ( like from the sun) can cause sunburn and skin cancer . That.s why it’s important to wear sunscreen and sunglasses to protect our bodies and and our eyes. X-rays are very high energy and like ultraviolet rays can cause damage to the body. But x-rays used at the right amount can be safe on the tissues and organs in our bodies. Hope this helps !
