Explanation:
Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves have all same speed in a vacuum (, known as speed of light) and are classified into 7 different types according to their frequency and wavelength. This classification is called electromagnetic spectrum.
From lowest to highest wavelength, the 7 types are:
Gamma rays
X-rays
Ultraviolet radiation
Visible light
Infrared radiation
Microwaves
Radio waves
Sound waves, on the contrary, do not belong to the electromagnetic spectrum, since they are another type of wave called mechanical waves (which consist of vibrations of the particles in a medium).
Answer:
=6.5%
Explanation:
Mass of the ball: ]
Initial velocity of the ball:
final velocity of the ball: which is -30/100 of
=
Mass of the bottle:
Initial velocity of the bottle:
final velocity of the bottle: is unknown (to find)
<em>by using conservation momentum, which stated that the initial momentum is equal to the final momentum.</em>
<em /><em />
<em>so since the bottle is at rest firstly, therefore </em><em />
<em /><em />
<em /><em> </em><em>equation 1</em>
so now substitute into equation 1
<em /><em />
<em>collect the like terms</em>
divide both side by
Now substitute
6.5%
