Question: An artificial satellite is in a circular orbit around a planet of radius r = 4.15 x 103 km at a distance d = 470.0 km from the planet's surface. The period of revolution of the satellite around the planet is T = 1.15 hours.
Part A: What is the average density of the planet?
Please show all steps to find the average density of the planet.
Cost per Power Capacity-For a number of energy technologies I'd like to know what the minimum costs are to install a given power capacity. Are there any such comparisons available?
In order to measure the radial velocity of a star (the speed of motion towards or away from us) what type of instrument would be used and how would the data be used to derive the velocity?
A particle of mass m in a three-dimensional harmonic oscillator of poterntial energy (m w^2 r^2)/2 has spectrum given by E=h bar w(2nr+l+3/2) where nr is the radial quantum number and l is the orbital angular momentum suppose the particle has charge ..
A fireman 44.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 32.0° above the horizontal. If the speed of the stream as it leaves the hose is 40.0 m/s, at what height will the stream of water str..

A hiker begins a trip by first walking 25.0 km 45.0° south of east from her base camp. On the second day she walks 40.0 km in a direction 60.0°north of east, at which point she discovers a forest ranger's tower.
Suppose that the magnetic field of the Earth were due to a single current moving in a circle of radius 2910 km through the Earth’s molten core. The strength of the Earth’s magnetic field on the surface near a magnetic pole is about 6.0·10–5 T. Ho..
