Answer:
The image behind the mirror is called a virtual image because it cannot be projected onto a screen—the rays only appear to originate from a common point behind the mirror. If you walk behind the mirror, you cannot see the image, because the rays do not go there
Answer:
<h3>The answer is 24.2 kgm/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 11 kg
velocity = 2.2 m/s
We have
momentum = 11 × 2.2
We have the final answer as
<h3>24.2 kgm/s</h3>
Hope this helps you
Let positive be west and negative be east because they
are contrasting in directions.
The forces are 4100, -830, and -1200
The sum of the forces is 4100 – 830 – 1200 = 2070 N.
Newton’s law F = ma is used.
2070 = 6800 a
Isolating a will give us 2070 / 6800 = a
a = 0.34 m/s^2
