5. You have 1) a block on a horizontal spring on a frictionless surface, and 2) a pendulum oscillating without friction. Both have the same period. Now if we take these to the Moon, where gravity is 1/6 that of Earth's, what will change? Choose all that apply. For the spring: a) The period of the spring will shorten. b) The period of the spring will stay the same. c) The period of the spring will increase. For the pendulum:...

1) Suppose you want to use a simple pendulum to measure accurately the acceleration of gravity around the Earth. Gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s2 on the Nevado Huascarán mountain in Peru to 9.8337 m/s2 at the surface of the Arctic Ocean (according to Wikipedia). Your pendulum has a length of 0.750 m, and you time its oscillations while you count 200 full periods in each location. What is the maximum error, in seconds,...

1. On occasion, the Earth-Moon-Sun system is aligned such that the Earth or Moon casts a shadow partially or directly on the other body. These events are called eclipses. A lunar eclipse happens when the Moon passes through the Earth’s shadow. A solar eclipse occurs when the Moon is in a position where it blocks sunlight from getting to Earth. A. Draw a Sun-Earth-Moon diagram for each kind of eclipse (lunar and solar). Make sure you draw your diagrams large...

Please make sure to answer all the questions correctly; 1.   In applying the gravity method, we subtract the scalar magnitude of normal gravity (gN) from the magnitude of the total component of the gravitational field (gT) to estimate the magnitude of gravity acceleration in the vertical to the ellipsoid (gz). Expand the error of this assumption using the binomial theorem to show that it is maximum at (gA2/gN), where (gA) is the magnitude of the gravity effect of the anomalous...
