A communications satellite orbiting the earth has solar panels that completely absorb all sunlight incident upon them. The total area A of the panels is 10m2. 1) The intensity of the sun's radiation incident upon the earth is about I=1.4kW/m2. Suppose this is the value for the intensity of sunlight incident upon the satellite's solar panels. What is the total solar power P absorbed by the panels? Express your answer numerically in kilowatts to two significant figures. 2) What is...

Two identical satellites orbit the earth in stable orbits. One satellite orbits with a speed v at a distance r from the center of the earth. The second satellite travels at a speed that is less than v.At what distance from the center of the earth does the second satellite orbit?At a distance that is less than r.At a distance equal to r.At a distance greater than r.Now assume that a satellite of mass m is orbiting the earth at a distance...

When you drop a 0.35 kg apple, Earth exerts a force on it that accelerates it at 9.8 m/s^2 toward the earths surface. According to Newton’s third law, the apple must exert an equal but opposite force on Earth. If the mass of the earth is 5.98x10^24 kg, what is the magnitude of the earth’s acceleration toward the apple? Answer in units of m/s^2.

Two satellites having equal masses are in circular orbits around Earth. Satellite A has a smaller orbital radius than satellite B. Which statement is true? A) Satellite A and satellite B have the same amount of mechanical energy (potential energy plus kinetic energy). B) Satellite A has more kinetic energy, more potential energy, and less mechanical energy (potential energy plus kinetic energy) than satellite B. C) Satellite A and satellite B have the same amount of kinetic energy and no...

2. Recall that in Homework 1, we found that the Sun exerts a force on the Earth almost 200x that of the Moon on the Earth. However, the Moon is clearly primarily responsible for ocean tides! Sir Isaac Newton correctly realized that it wasn't the strength of this gravitational force that produced tides, but the fact that the Sun and the Moon pulled harder gravitationally on one side of the Earth than the other. Thus, the change in gravitational force...

You swing a bat and hit a heavy box with a force of 1500 N. The force the box exerts on the bat is A. less than 1500 N if the box moves. B. greater than 1500 N if the box moves. C. greater than 1500 N if the bat bounces back. D. exactly 1500 N only if the box does not move. E. exactly 1500 N whether or not the box moves.

The moon does not fall to earth because: The moon is beyond the main pull of Earth's gravity. The moon is pulled by the sun and planets as well as by Earth. The gravitational force provides the required centripetal force for the moon to have its tangential speed around the Earth. The net force on the moon is zero. The moon is in earth's gravitational field. Question 3 (4 points) The tallest mountain in our solar system is Mt. Caloris...
