Three different experiments are conducted that pertain to the oscillatory motion of a pendulum. For each experiment, the length
of the pendulum and the mass of the pendulum are indicated. In all experiments, the pendulum is released from the same angle with respect to the vertical. If the students collect data about the kinetic energy of the pendulum as a function of time for each experiment, which of the following claims is true? a. The data collected from Experiment 1 will be the same as the data collected from Experiment 2.
b. The data collected from Experiment 1 will be the same as the data collected from Experiment 3.
c. The data collected from Experiment 2 will be the same as the data collected from Experiment 3.
d. The data collected from each experiment will be different.
If you mean the Lexington in Oregon, it's 5:30 there. If you mean the Lexington in Texas, it's 7:30 there. If you mean the Lexington in Massachusetts or the one in Kentucky, it's 8:30 in both of those.
Answer: The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. ... As it moves around Earth, more and more of the lit side comes into view. Then it begins to disappear again. It takes 29.5 days for the Moon to orbit Earth.
