in the absolute gravity observation instruments, the body is released allowed to fall in a vacuum. if the length of the vacuum is 22 meters and the body falls at the given distance in 2.118 seconds.what is the value of gravity at that instant

Which of the following is the variation of acceleration due to gravity at a depth “d” below the earth’s surface? Let “R” be the radius of the earth and “M1” the mass of earth. (Assume the density of the earth to be constant) a) g = (G*M1)/(R – d) b) g = [(G*M1) x density]/d c) g = (G x M1/R3) / (R – d) d) g = (G x M1/R3) x (R – d)

A body with a mass of 10.0 kg is assumed to be in Earth’s gravitational field with g = 9.80 m/s2 . What is its acceleration?

The free-fall acceleration on the surface of a fictional planet is about 1/2 that on the surface of the Earth.. The radius of the planet is about 0.71RE (where we use the symbol RE = Earth's radius). Find the ratio of their average densities, pp/Pɛ. Please feel free to look up the earth"s radius in the table in your text-book.

For a body at a height of 200m, what is the body's velocity when it reaches the earth's surface and the mass of the body is 25kg

The mean diameters of Mars and Earth are 6.9 * 103 km and 1.3 * 104 km, respectively. The mass of Mars is 0.11 times Earth’s mass. (a) What is the ratio of the mean density (mass per unit volume) of Mars to that of Earth? (b)What is the value of the gravitational acceleration on Mars? (c) What is the escape speed on Mars?

The mean diameters of X and Y, two planets in the same solar system, are 6.5 x 10³ km and 1.2 x 104 km, respectively. The mass of x is 0.21 times the mass of Y. The value of g on Y is 8.1 m/s². (a) What is the ratio of the mean density of X to that of Y (Px / Py)? (b) What is the value of g on X? m/s² (c) The mass of Y is 4.372 x 1024 kg. What is the escape speed on X? m/s

A scientist is on a 3.07×103 high mountain top with a gravimeter that records the free fall acceleration. What is the difference between the acceleration due to gravity at sea level and the acceleration due to gravity he will record? Take the radius of the earth to be 6370000 m and the mass of the earth to be 5.98×1024 kg.  0.0189 m/s2 3.02×104 m/s2 0.00947 m/s2 9.82 m/s2

Concern the planet Mars, which has a radius of 3400 km. On Mars, the acceleration due to gravity is 3.72 m/s^2 The mass of the sun is 2.0×1030 kg, while the (actual) mass of Mars is 6.4×1023 kg. The average distance from Mars to the sun is 228 million kilometers. a. What is the gravitational force acting on Mars due to the sun? What is the reaction force to this force? Name or explain the force; don’t give a value. b. What are the speed and angular velocity of Mars? Compare the values to those of Earth. c.
