Given:
Therefore, the acceleration is,
<h3>
Explain Acceleration?</h3>
An object's rate of changing its velocity is known as its acceleration, which is a vector quantity. If an object's velocity is changing, it is accelerating. When anything moves faster or slower in a straight line, it is said to have been accelerated. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

Answer:Due to the pressure difference created by rotating fans.
Explanation:
In most of the vacuum cleaners, there is an area which is of disc shape and it is in right next to the motor. There are several fans within the disc that spin at a very high velocity.
The blades will push the air outside of the disk.There is no air in inside of the disc and air pressure creates which pushes air inside the disk to replace the missing air.
So motor is pushing the air outside and to maintain this pressure the air is pushing toward inside with dirt.
In a generator, mechanical
energy is converted electrical energy. The answer is letter D. the mechanical
energy in the generator produces energy by making the machines work and then transmitting
this into the power lines of commercial industries, communities and others.
Answer:
= 351.84 J
Explanation:
Using the conservation of energy K:
so:
where m is the mass, v the initial velocity, is the kinetic energy of the mass as it clears the fence, g the gravity and h the altitude.
Then, replacing values, we get:
solving for :
= 351.84 J
