The answer is 1 day. I need to know how to solve this step by step. thank you The moon has a period of 27.3 d and is an average distance from Earth of 3.84 × 105km. A communications satellite is placed in an Earth orbit at 4.23 × 104 km from the center of Earth. What is the period of this satellite?

The intensity of light from the sun that is seen at the top of the earth's atmosphere is 1366 W/m² Given that the earth is 1.50 x 1011 m from the sun. (a) What is the total power output of the sun? (b) What is the average strength of the electric and magnetic fields of the electromagnetic waves from the sun in our upper atmosphere? (c) What would the...

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...

1. The intensity of a particular earthquake wave is measured to be 1.60 x 106 W/m2 at a distance of 40.0 km from the source. What was the intensity when it passed a point only 1.00 km from the source? Assume that earthquake waves travel uniformly in all directions W/m2 2. The team monitoring a space probe exploring the outer solar system finds that radio transmissions from the probe take 2.10 hours to reach earth. How distant (in meters) is...

Question1. A U.S. or Canadian broadcasting licence for a (large) FM radio station stipulates a maximum broadcast power of 100 kW. At any distance from the broadcast antenna the intensity doesn’t quite follow the inverse square law that is described for spherical waves in the videos lectures, because of reflection of the signal off of the ground. But the inverse square law is not a bad approximation, so let’s use it a) Find the intensity of the radio signal from...

1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...

Acceleration due to gravity on board of your spaceship that orbits Jupiter is 25.89 m/s. How high is your spaceship above Jupiter's cloud tops? Express your answer in kilometers and round it to the nearest integer. M Jupiter = 1.90 x 104 kg; R Jupiter = 69,911 km. Your cosmic journey brought you into the vicinity of a neutron star. In fact, you are orbiting this neutron star at an orbital distance of 22.424 kilometers. The neutron star has mass...

1) The Solar and Sidereal days difer from each other by about 4 minutes. How much distance, relative to the Sun and in km, does the Earth travel during that time? (You may approximate the Earth's orbit as a perfect circle.) 2) How many degrees does the Moon move in its orbit during one Earth-day. Use the Moon's orbital period relative to distant stars, i.e. use its sidereal period. 3) a) Since the Earth makes one full revolution every 24...
