The correct answer (sample response) is:

The image seems to be behind the mirror, but nothing is really there.

Include the following in your response:

The image appears to be behind the mirror.

If someone looks behind the mirror, there is no image there.

Answer:

A plane mirror forms a virtual, erect, same size and laterally inverted image. Virtual means that the image is not real and cannot be obtained on screen. It means the rays appear to meet behind the mirror but when you will actually go behind, you will find nothing. A virtual image is always erect.

A real image is always inverted. It can be obtained on the screen. Rays actually meet at a point.

How do you think density plays a role in the atmosphere?
Feliz [49]
Answer:
Also, gases like air are easily compressed. The weight of all the air above a given point in the atmosphere squeezes air molecules closer together. This causes the density to increase. The more air above a level (and hence the more weight of air above a level), the greater the compression.

In each cycle, a heat engine performs 710 J of work and exhausts 1480 J of heat. What is the thermal effiency?
Tomtit [17]

Answer:

32%

Explanation:

For a heat engine, efficiency is work out divided by heat in:

η = Wₒ / Qᵢ

Since energy is balanced, heat in is the sum of work out and heat out:

Qᵢ = Wₒ + Qₒ

Therefore:

η = Wₒ / (Wₒ + Qₒ)

Given Wₒ = 710 J and Qₒ = 1480 J:

η = 710 / (710 + 1480)

η = 0.32

The thermal efficiency is 32%.
