The angle is 53.5 degrees.

What is a flat mirror?

A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.

This ques have been solved in two steps:

Step 1:

given that;

Θ=107 degrees

from figure,

∠BAC=180-ψ-(90-φ)

∠BAC= 90-ψ-φ

∠AOC=180-2(ψ-φ)-2φ

∠AOC=180-2φ

Step 2: part(a)

writing an expression for the psi at point o:

Θ+180-2ψ=180

2ψ=Θ

ψ=Θ/2

above is the expression for ψ

Step 3: part(b)

The angle of ψ is,

ψ=Θ/2

ψ=107/2

ψ=53.5 degrees

Hence, the angle is 53.5 degrees.

What is 1.2 kg converted into mg.<br> I need to know for step by step please?
astra-53 [7]
Here’s a good photo to reference when converting in the metric system.

Each time you move down a step you move the decimal to the right, each time you move up a step you move the decimal to the left.

We are going from 1.2 kg or kilograms, which is at the very top left of the ladder. To get to mg or milligrams, we would have to make six jumps, so we’d move the decimal over six times.

1.2 > 12. > 120. > 1200. > 12000. > 120000. > 1200000.

So our final answer would be 1,200,000mg.

Name two examples of deposition.
Rashid [163]
The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.

mote1985 [20]

The rocky object orbiting in space is most likely referred to as an asteroid.

<h3>What is an Asteroid?</h3>

This is referred to a rocky object which revolve around the sun and are considered too small to be called a planet.

Asteroids was observed with the use of a telescope and is around 250 km wide thereby making it the most appropriate choice.

AfilCa [17]

Answer:

C    Don't worry if you thought it was D. I almost answered that.

Explanation:

Remark

You can get this just by learning the vocabulary.

Efficiency = Work Out / Work In * 100%

Work in = 30J      That's you swinging the hammer.

Work out = 10 J    That's how much of the hammer's work gets to the nail.

Efficiency = (10/30)*100

Efficiency = 1/3 * 100

Efficiency = 33%
