6 meters is left because you subtract 12 meters from 6
Answer:
The balloon will move forward.
The density of the air will be greater at the back of the balloon; similar
to the density of air being greater at lower altitudes due to gravitational
attraction because of the weight of the air in an air column.
A block of wood in water rises because of the difference in pressures
on the top and bottom of the block.
Answer:
Plenum cabling
Explanation
As the plenum cabling are fire resistent so it will not cause the toxic components in case of fire.
Answer:
Explanation:
From work energy theorem
Work done by all forces = Change in kinetic energy
Lets take
m= mass of object
h=height from the ground surface
initial velocity of object = 0 m/s
The final velocity of object is v
Work done by gravitational force = m g . h
The final kinetic energy = 1/2 m v²
So
Work done by all forces = Change in kinetic energy
m g h = 1/2 m v² - 0
v² = 2 g h
This is not something that waves do because they need a medium to travel through, while particles do not.
<h3>How light travels in space?</h3>
A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.
So we can conclude that electromagnetic waves like light do not require medium for its propagation.
