In the future, astronauts are on a distant moon that is 618.9 km in diameter.
While there, they observe that a 2.0 m long pendulum takes 5.623 times longer than the pendulum did, when it was back on Earth.
What is the mass of the moon?
Round your answer to 4 significant figures in units of kg.

The mass of the Moon is 7.4x1022 kg, and its diameter is 3474 km. During the Apollo landings, once reaching the Moon two astronauts would get into the Lunar Module from the Command Module. The LM would then separate from the CM and descend to the surface. What is the speed of the LM, in a circular orbit around the Moon at an altitude of 277km What is the period of that orbit?
Suppose that in the not so distant future an astronaut on the Moon turns on a 100 W light bulb during a lunar eclipse (i.e. the Moon becomes dark as seen from Earth). You can assume that all of the emitted power is in the visble. The light is emitted uniformly in all directions. a) Calculate the number of photons per second emitted by the light bulb. b) In the dark, when your pupils are dilated, they have a diameter...
An ice covered moon, with a mass of 3.575×1020 kg and a diameter that equals 494.6 km, has an eruptive geyser that sprays a water mixture 247.0 km above the moon's surface. With what velocity was the geyser spray coming out of the moon's crust? Note, as the geyser's height is large compared to the moon's diameter, you will need to calculate for the geyser's potential and kinetic energies at the top and bottom of its eruption. Round your answer...
A) For the next scene, an astronaut travels to a moon of Planet W. She needs to measure the local gravity on the planet. She decides to use a 1.5 m long pendulum. She finds it takes her pendulum 6.09 seconds to complete one full oscillation. What is the acceleration due to gravity on this moon? a. 1.6 m/s2 b.2.1 m/s2 c. 2.3 m/s2 d.1.9 m/s2 B) For the next scene, an astronaut travels to a moon of Planet W....
Jupiter's moon lo has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 km (or even higher) above the surface, lo has a mass of 8.93 times 10^22 kg and a radius of 1821 km. For this calculation, ignore any variation in gravity over the 500-km range of the debris. part A How high would this material go on earth if it were ejected with the same...
Need some help answering this question. Please show all
work and use appropriate units. Thanks.

Suppose that a crazy around the Earth, so that the satellite etes ctly 5 orbits of the during every 3 orbits of the Moon. compl Earth (Assume that both orbits are circular.) a. (3 pts. Calculate the ratio of the orbital radi of the satellite and the Earth's Moon....
A 60 cm -diameter potter's wheel with a mass of 30 kg is spinning at 180 rpm. Using her hands, a potter forms a 14 cm-diameter pot that is centered on and attached to the wheel. The pot's mass is negligible compared to that of the wheel. As the pot spins, the potter's hands apply a net frictional force of 1.3 N to the edge of the pot. If the power goes out, so that the wheel's motor no longer...
If you dropped a rock from a height of 1.1 m on 243 Ida, how long would it take to reach the ground? Express your answer to two significant figures and include the appropriate units. If you can jump 62 cm straight up on earth, how high could you jump on 243 Ida? (Assume the asteroid's gravity doesn't weaken significantly over the distance of your jump.) Express your answer to two significant figures and include the appropriate units. The asteroid...
Newton’s Cannon Imagine you fired a cannonball such that the range of that ball was slightly longer than the radius of the Earth. As that ball fell back down, it would miss the ground and continue to fall. If we can ignore any air resistance or collisions with other objects, then we can say the ball would continue to fall forever, just missing the ground, and thus be in orbit. Assume all orbits here are perfectly circular and pretend that...
For each of the following, you’ll need to perform dimensional analyses. Show your work, use significant figures and show all conversion factors you use. You may need to use some of the conversion factors or equations below and you many need to look some up. 1 mole = 6.02x1023 atoms mass of a gold atom = 3.27 x 10-22 g radius of a gold atom = 174 picometers density of gold = 19.3 g/mL volume of a sphere = 4/3πr3...
