When will you attract the sun more: today at noon, or tonight at midnight? Explain.

Short Answer

Expert verified

You will attract the sun at noon.

Step by step solution

01

Direction of effective force between Sun and Earth

The gravitational force between the sun and Earth acts on each other in the opposite direction at noon but acts in the same direction at midnight.

02

Whether you will attract the sun more at noon or midnight

The effective force of a person on the sun is less at midnight because the effective force between the sun and earth is in the same direction.

The effective force of a person on the sun is more at noon because the effective force between the sun and earth is in the opposite direction.

Therefore, you will attract the sun at noon.

Question: How many nanoseconds does it take light to travel 1.00 ft in vacuum? (This result is a useful quantity to remember.)?

Calculate the earth’s gravity force on a 75-kg astronaut who is repairing the Hubble Space Telescope 600 km above the earth’s surface, and then compare this value with his weight at the earth’s surface. In view of your result, explain why it is said that astronauts are weightless when they orbit the earth in a satellite such as a space shuttle. Is it because the gravitational pull of the earth is negligibly small?

If AandBare nonzero vectors, is it possible for both A·BandA×Bto bezero? Explain.

You are on the roof of the physics building, 46.0mabove the ground (Fig. P2.70). Your physics professor, who is1.80mtall, is walking alongside the building at a constant speed of1.20m/s. If you wish to drop an egg on your professor’s head, where should the professor be when you release the egg? Assume that the egg is in free fall.

(Fig. P2.70)

A Simple Reaction-Time Test.A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. When you see the meter stick released, you grab it with those two fingers. You can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingers grabbed it. (a) Derive a relationship for your reaction time in terms of this measured distance, d. (b) If the measured distance is 17.6 cm, what is your reaction time?
