Three 7.50-kgkg masses are at the corners of an equilateral triangle and located in space far from any other masses. a) If the sides of the triangle are 1.21 mm long, find the magnitude of the net force exerted on each of the three masses. b) How does your answer to part A change if the sides of the triangle are doubled in length?

NEXT Chapter 04, Problem 032 Chalkboard Video A spacecraft is on a journey to the moon. At what point, as measured from the center of the earth, does the gravitational force exerted on the spacecraft by the earth balance that exerted by the moon? This point lies on a line between the centers of the earth and the moon. The distance between the earth and the moon is 3.85 × 108 m, and the mass of the earth is 81.4 times as great as that of the moon. moon m earth em

A 15.0 kgkg sphere is at the origin and a 5.00 kgkg sphere is at x� = 20 cmcm.     Part A At what position on the x�-axis could you place a small mass such that the net gravitational force on it due to the spheres is zero? Express your answer with the appropriate units.

Task 1: Gravitational Fields 1. A person with a mass of 60 kg is inside a rocket that is moving straight up, away from the earth's surface. The radius of the earth is 6.38 x 105 m and the mass of the earth is 5.98 x 1024 kg. a. Find the force of gravity acting on the person at an altitude of 300 000 m. b. Find the altitude that will cause the person's weight to drop to one-quarter of its value on the earth's surface. 2. Mass 1 is four times as large as mass 2. Both masses are at rest and are separated by 200 m. Where could you place a third mass, mass 3, if the net force on 3 must be zero?

An astronaut takes a set of scales to do some measurements while travelling. Before leaving earth, the astronaut stands on the scales and they read "75 kg". Determine what the readings would be in the following circumstances. (You will first need to decide what the scales physically relate to).

The values of gravitational acceleration at the surfaces of Jupiter, Pluto, and the sun are 23.12 m/s, 0.72 m/s, and 273.98 m/s, respectively. Determine your weight at each of these locations in both SI and US customary units. Assume no loss of mass results from the extreme conditions.

G = 6.67 ×10 -11 m 3 /kg/s 2 Some people claim that the location of Jupiter can have dramatic consequences on human events on Earth. For comparison to the last problem, what is the force of gravity due to a 100 kg person hugging a 60.0kg ASTR 110 student. Assume the distance between the students is 0.3 meters.

Answer both questions please

An astronaut is doing a spacewalk on a long tether at 0.1 km away from the International Space Station (mass of 420,000 kg). His spacesuit includes a very sensitive gravitometer, which indicates the gravitational force acting on the astronaut and his spacesuit from the ISS is 7.0 E−7 N. What is the mass of the astronaut in his suit if G = 6.67 E−11 N*m2/kg2? 1. 150 kg 2.  200 kg 3. 250 kg 4. 300 kg

Take the larger object to be at x = 0 with the right side as positive. Here, m₁ = 10.0 kg, m₂ = 3.00 kg, and d = 0.600 m. Locate a point x3 along the line AB where a small, 1.00-kg object could rest such that the net gravitational force on it due to the two objects shown is exactly zero. A x3 = m₁, Select how many such points exist. öööö d m₂ B m
