- The planet Jupiter has a mass of 1.9 × 1027 kg and a radius of 72,000 km. The Earth, meanwhile, has a mass of 6.0 × 1024 kg and a radius of 6,400 km. What is the volume of Jupiter in m3? Show calculatiSuppose you could pack neutrons (mass = 1.67 × 10-27 kg) inside a small ball of radius 0.026 m in the same way as neutrons and protons are packed together in the nucleus of an atom. (a) Approximately how many neutrons would fit inside the ball? (b) A small object is placed 3.7 m from the center of the neutron-packed ball, and the ball exerts a gravitational force on it. When the object is released, what is the magnitude of the acceleration that it experiences? Ignore the gravitational force exerted on the object by the earth.That's what I thought too! But the answer choices it gave were 8 m/s, 4 m/s, 2 m/s, and 6 m/s so I'm confused. I went with 8 and it was wrong.
- Consider the gravitational acceleration on the surface of the Moon and of Mars. a) What is the acceleration, in meters per square second, due to gravity on the surface of the Moon? You will need to look up the mass and radius of the Moon. b) What is the acceleration, in meters per square second, due to gravity on the surface of Mars? The mass of Mars is 6.418 × 1023 kg and its radius is 3.38 × 106 m. Given: the radius of the moon is 1,080 milesA proton is located at (0, 0, -1.0 x 10-9) m, and an alpha particle (consisting of two protons and two neutrons) is located at (1.0 x 10-9, 0, 2.5 x 10-9) m. (Express your answers in vector form.) (a) Calculate the force the proton exerts on the alpha particle. XN (b) Calculate the force the alpha particle exerts on the proton.
