In all parts of this problem, assume the planet is located at its mean distance from the Sun as shown in Chapter 5 of the textbook. (These same distances can be found at http://theanswermachine.tripod.com/id2.html.)
How long would it take a message sent as radio waves from Earth to reach the following?
(a) Mars when it is nearest to Earth
minutes
(b) Pluto when farthest from the Earth
minutes
When nearest - 33.9 million miles - 3.03 minutes.
at the farthest- 294.16 million miles - 26.35 minutes.
Both have elliptical orbits, hence the great difference in the
distance.
In all parts of this problem, assume the planet is located at its mean distance from...
Chapter 24, Problem 02 (a) Neil A. Armstrong was the first person to walk on the moon. The distance between the earth and the moon is 3.85 x 108 m. Find the time it took for his voice to reach the earth via radio waves. (b) Someday a person will walk on Mars, which is 5.60 x 100 m from the earth at the point of closest approach. Determine the minimum time that will be required for a message from...
In our derivation of Kepler's laws, we assumed the only force on a planet is due to the Sun. In a real solar system, however, the gravitational forces from the other planets can sometimes be important. Calculate the gravitational force of Jupiter on the Earth. Do the calculations for the cases when Jupiter is both closest (Fc) to and farthest (Ff) from the Earth (see the figure below). (The properties of several objects in the solar system are given in...
NASA is still in communication with the Voyager 1 spacecraft, 41 years and 7 months after its launch. The spacecraft is currently at a distance of about 145 Astronomical Units (AU), or over 4 times the current distance to Pluto. How long did it take a bit of data in a radio signal stream from the spacecraft to reach the Earth where the Deep Space Network's 70-meter dishes detects faint signals? [1 AU 150 million km; c3x105 km/s; speed distance/time.]...

answer all please Problem 1. A block of mass m = 735 g is located on an incline which makes an angle of 40 with the horizontal The friction coefficient between the block and the incline is K = 0.21. The block is released and it is let slide down the incline. (a) Draw a free body diagram and identify all forces acting on the block. Find the acceleration of the block (b) If the block moves d = 0.42...
The sidereal year of a planet is related to the distance of the planet from its sun through a power equation. The following data for a distant solar system show the distances its planets are from their sun and the planets' sidereal years. Complete parts (a) through (d). Distance from sun, x (Millions of miles) 40 Sidereal Year, y 0.29 109 1.27 187 2.84 791 24.39 1822 84.56 2567 140.93 3367 211.15 (a) Draw a scatter diagram treating distance from...
4. Consider the network shown below, and assume that each node initially knows the costs to each of its neighbors. Consider the distance-vector algorithm. 6 2 What are the distances from y to all other nodes after y receives one message from each of its direct neighbors (assuming that these messages are the only messages that have been sent and received so far in the entire system)? What are the distances from x to all other nodes after x receives...
