*Please help this is my final* If the car has a mass of 700 kg, how many newtons of forxe were used to accelerate it 30m/s/s

Vaselesa [24]

Answer:

21,000 N

Explanation:

You would use the formula F=ma

So you would do substitution...

F=700 kg(30 m/s/s)

F=21,000 N

A 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. what is its potential energy (PE) when it is 2.00 m above the grou

IceJOKER [234]

The potential energy is 4.10 J

Explanation:

The potential energy of a body is given by

$U=mgh$

where

m is the mass of the object

g is the acceleration of gravity

h is the height of the object relative to the ground

For the lemming in this problem we have

m = 0.078 kg is its mass

h = 5.36 m is the height above the ground

$g=9.8 m/s^2$ is the acceleration of gravity

Solving the equation,

$U=(0.078)(9.8)(5.36)=4.10 J$

Electromagnetic waves carry energy. This phenomenon is also called electromagnetic radiation. How is energy transferred in elect

Anastasy [175]

Answer:

Energy is carried by the electric and magnetic fields

Explanation:

Electromagnetic waves consist of electric fields and magnetic fields which oscillate perpendicularly to the direction of propagation of the waves (for this reason, they are called transverse waves).

Electric fields and magnetic fields both possess energy, and this energy is carried through space by the wave. Note that electromagnetic waves do not carry matter, but only energy (in fact, they do not have mass). Moreover, electromagnetic waves are the only type of waves that do not need a medium to propagate: in fact, they can also travel through a vacuum.
