(10 Points) The moon revolves about the earth in a circle (very nearly) of radius R =239,000 mi or 12.6 X 108 ft, and requires 27.3 days of 23.4 X 105 sec to make a complete revolution. (a) What is the acceleration of the moon towards the earth? (Ans: a = 8.96 X 10-3 ft/sec) (b) If the gravitational force exerted on a body by the earth is inversely proportional to the square of...

6. [10 points) For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Work with the approximate value g = 9.8 m/s2 for the Earth's gravitational acceleration. Consider the following experiment. The Leaning Tower of Pisa is known worldwide for its nearly four- degree lean. The height of the tower is 55.86 meters from the ground on the low side, and 56.67 meters on the high side....

We want to get better, more concrete
We want to get a better, more concrete idea of the strength of the electric force. So imagine you could remove all the electrons from 1 mL (1 cubic centimeter) of water. Dump the electrons on yourself, and put the electron-free nuclei (protons and neutrons) on the moon. Estimate how much force will there be between the positive and negative charges? (Of course you have to look up the earth-moon distance.) What fraction of your weight is that force?(How many...

1) Strength of the electric force The earth and the moon exert attractive gravitational forces on one another according to Newton's law of gravitation. However, since the earth and the moon are electrically neutral (that is, the net charge of each planet is zero), they do not exert electrical forces on one another. Assume now that someone (aliens) removes some number N of electrons from both the earth and the moon, so that the two bodies now exhibit electrical repulsion...

Work and exact values please! Thank you
Sketch the electric field and equipotential contours for the arrangement shown below. Use the PhET simulation if necessary. Consider the electric field lines drawn below for a configuration or two charges. Five points (A-E) are labeled on the diagram. Rank these locations in order of the electric field strength from smallest to largest. Calculate the net electric potential at point A in the diagram shown above. The net potential is the sum of...

1. [25 points) Idealized frictionless free fall of an object that is dropped from being at rest at i = 0. For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Consider the following experiment. A rock with a mass of m= 2 kg is dropped at the time t = 0 from a height of 140 m above ground. Assume that the rock is simply dropped...
