what are the magnitude and direction of the gravitational force exerted on Moe by 11.lf Moe exerts a gravitational force of 3.65 x 10-8 N on Larry, who is standing east of him, 10.If an object on the earth experiences a gravitational force of 25 N toward the center of the earth, what are the magnitude and direction of the force the object exerts on the earth? Larry? If each man has a mass of 70.0 kg, how far apart are they standing? If Curly were to bump into Moe, knocking him halfway to Larry, how would the new gravitational force between Moe and Larry compare to the original? a. ¼ as great b. ½ as great c. the same d. twice as great e. four times as great

Question 4 Please !!!

Planet Kling has half the radius and 2 times the mass of the Earth. What is the best estimate for the magnitude of the gravitational field at the surface of Planet Kling?

a.) Find the net force on the Moon (mM=7.35×1022kg)(mM=7.35×1022kg) due to the gravitational attraction of both the Earth (mE=5.98×1024kg)(mE=5.98×1024kg) and the Sun (mS=1.99×1030kg)(mS=1.99×1030kg), assuming they are at right angles to each other (Figure 1). Express your answer to three significant figures and include the appropriate units. Fnet= __________ ____________   b.) Determine the direction of the net force. Express your answer to three significant figures and include the appropriate units. θ= ______________ ___________

One model for a certain planet has a core of radius R and mass M surrounded by an outer shell of inner radius R, outer radius 2R, and mass 4M. If M = 4.07 × 1024 kg and R = 5.79 x 106 m, what is the gravitational acceleration of a particle at points (a) R and (b) 3R from the center of the planet? (a) Number i Units (b) Number i Units

Tidal forces are gravitational forces exerted on different parts of a object by a second object. Their effects are particularly visible on Earth's surface in the form of tides. To understand the origin of tidal forces, consider Earth-Moon system to consist of two spherical bodies, each with a spherical mass distribution. Let RE be the radius of Earth, m be the mass of the Moon, and G be the gravitational constant. Part B Since the gravitational force between two bodies decreses with distance, the accelaeration a(near) experienced by a unit mass located at the point on the earth's surface closest to moon is slightly different from the acceleration a(far) experienced by a unit mass located at the point on the earth`s surface farthest from the moon. Give a general expresion for the quantity a(near)- a(far).
