the sun has mass 330000 times that of the earth for a person on the earth the average distance to the center of the sun is 23500 times the distance to the center of the earth in magnitude what is the ratio of the sun gravitational force on you to the earth gravitational force on you​

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
