Can a plane mirror produce a real image? Explain.

Answers

I don't think so, because in order to produce an image, you need a surface behind the mirror. The light will hit the mirror, then it will bounce it back in your eyes and you see the image.

Mrs. Patil travels from her home to work in 0.25 hours. The direct distance between her home and work is 8.0 miles. If Mrs. Patil travels 12.4 miles from home to her job, what is her average velocity during the trip?

Answers

Regardless of the path taken, at the end of the trip Mrs. Patil will be 8.0 miles away from home. If the path taken involves a trip lasts 0.25 hours, then the average velocity over the trip is

\frac{8.0\,\mathrm{mi}}{0.25\,\mathrm h}=32\,\frac{\mathrm{mi}}{\mathrm h}

Evaporation: Large amounts of water evaporates from the Earth's ________, _______, __________ every day. The water vapor (evaporation) becomes part of the ________.

Answers

my guesses would be 

surface,oceans,rivers,atmosphere

Possible answers:

oceans/seas/lakes/rivers

atmosphere/sky

Explanation:

Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

To calculate power, divide the amount of energy transferred by...?

Answers

Fairly simple...the answer is time.

Power, as you should have learned in your class, is a rate; it needs to be multiplied by time to get the amount of energy 

Thus, your answer...time.

To calculate power, divide the amount of energy transferred by time.

Final answer:

Power in physics is the rate of energy transferred per unit time. It can be calculated by dividing the amount of energy transferred by the time required for the transfer.

Explanation:

In Physics, power is defined as the rate of transferring energy or the amount of energy per unit time. If you want to calculate the power, you take the amount of energy transferred and divide it by the time it takes for that transfer to occur. For example, if a light bulb transfers 100 joules of energy over 10 seconds, the power would be 100 joules divided by 10 seconds, which equals to 10 watts.
