A 50 kg man is standing at the Earth's surface. (a) What is the approximate magnitude of the gravitational force on the man by the Earth. Give your answer in newtons. Get the mass and radius of the Earth from the inside front cover of your text. Remember, enter only the number; don't try to enter the units.
? N
(b) What is the approximate magnitude of the force of gravitation on the same man by the Sun. You may approximate the distance from the Sun to the man by the distance from the Sun to the Earth; get that distance, as well as the mass of the Sun, from the inside front cover of your book.
? N
(c) What is the approximate magnitude of the force of gravitation on the same man by the Moon. You may approximate the distance from the Moon to the man by the distance from the Moon to the Earth; get that distance, as well as the mass of the Moon, from the inside front cover of your book.

Neutrons are placed in a magnetic field with magnitude 2.30 t. part a part complete what is the energy difference between the states with the nuclear spin angular momentum components parallel and antiparallel to the field? δe δ e = 2.77×10−7 ev previous answers correct part b part complete which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? parallel antiparallel previous answers correct part c part complete how do your results compare with the energy states for a proton in the same field (δe=4.05×10−7ev)? how do your results compare with the energy states for a proton in the same field this result is smaller than but comparable to that found in the example for protons. this result is greater than but comparable to that found in the example for protons. previous answers correct part d the neutrons can make transitions from one of these states to the other by emitting or absorbing a photon with energy equal to the energy difference of the two states. find the frequency of such a photon. f f = mhz previous answersrequest answer incorrect; try again; 5 attempts remaining
