The lunar werewolves have decided to take over the earth on Halloween. The werewolves have decided to flip the moon so that the full moon lasts longer on earth. How fast does the earth spin after the moon is flipped?
The moon is a spherical body. The phases of the moon i.e. from the new moon to the full moon happens due to the position of the moon in the Earth's orbit. When the moon comes exactly in between the Earth and the Sun, we see a new moon because the illuminated part is facing the sun. Now even if we flip the moon, the illuminated part will still be facing away from the Earth just that the side of the moon will change. Now as the moon moves away from that position the moon becomes visible bit by bit. This the Earth's spin won't be affected at all.

a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall...

These are the answers, please provide the work for the calculation 1. Two cells that subdivide on Earth every 10.0s start from the Earth on a journey to the Sun (1.5 x 1011 m away) in a spacecraft moving at 0.850c. How many cells wil exist when the spacecraft crashes into the Sun? Earth time is 588s. Spacecraft time is 310s or 31 cycles of division. 2312.1x 10 cells at the end of the journey. 2. As a spacecraft moving...

c. Remember that a light-year is defined as the distance, relative to Earth, that light travels in one calendar year on Earth. If Alpha Centauri is 4.37 light-years away from Earth, what is this distance measured by you from your spaceship? d. You and your twin decided to synchronize your clocks before you started your trip so you can compare the length of your trip once you get back. i. How long does it take the spaceship to reach its...
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...
You have decided that 20 years after the day you start working full time you will take a leave of absence for avocation around the world. To save money for this vacation, you found an investment that pays 4% nominal interest, compounded annually, and you believe you need $150,000 in that account when you take your trip. You will make end of year deposits every year for the 20 years while working (including the end of your 20th year), and...

Researchers have investigated the preferences over dinner and they have found that they take the following form: U = - 68 Chicken + 21 Steak + 4 Fish - 43 Costs Costs= cost in dollars of the dinner Chicken= amount of chicken in pounds Steak= amount of steak in pounds Fish= amount of fish in pounds Given this information, how many pounds of fish is the consumer willing to give up to obtain one more pound of steak during...
Determine the acceleration due to gravity for low Earth orbit (LEO) given: MEarth = 6.00 x 1024 kg, rEarth = 6.40 x 106 m, G = 6.67 x 10-11m3kg-1s-2, and LEO is 400 km above Earth's surface. How fast are objects in low Earth orbit (LEO) traveling given: MEarth = 6.00 x 1024 kg, rEarth = 6.40 x 106 m, G = 6.67 x 10-11 m3kg-1s-2, and LEO is 400 km above Earth's surface. Assume objects orbit with uniform circular...
Rivka is an active 21-year-old who decided to take a day off from her university classes. The weather was hot and the sun bright, so she decided to go down to the beach. When she arrived, she found a few people playing beach volleyball, and they asked if she wanted to join in. She put down her school bag and began to play. The others were well prepared for their day out and stopped throughout the game to have their...
