A satellite that goes around the earth once every 24 hours is called a geosynchronous satellite. If a geosynchronous satellite is in an equatorial orbit, its position appears stationary with respect to a ground station, and it is known as a geostationary satellite. A. Find the radius R of the orbit of a geosynchronous satellit

Please see the attached file. According to the Schrodinger atomic model, each quantum state of an atom or ion can be labelled using two quantum numbers n and l. Write down a formula for the energy of each of the quantum states of the hydrogen like boron ion B4+. For a given value of n, state how the number of quantum s
In the Bohr model of the hydrogen atom, an electron can orbit a proton (the nucleus) in a circular orbit of radius 4.76x10^-10m. What is the electric potential at the electron's orbit due to the proton?
The electron of a hydrogen atom is initially at the orbit n=4. If this electron first goes to the orbit n=3 and then to the orbit n=2 and then to the orbit n=1, how many photons are emitted during these transitions? How many photons are emitted if the electron directly falls from the orbit n=4 to the orbit n=1?

Imagine a space station module shaped like a cylinder 30m long and 5m in diameter orbiting close to the earth above the earth's equater. What would be the maximum potential difference that could develop between the ends of the module. (I know that potential difference=EL but how do I find E? It is also equal to VB/C or v*magnet
Why are the synodic and sidereal period of moon different?
The solar wind is a continuous stream of particles, mostly protons and electrons, moving away from the Sun. When the particles encounter Earth's upper atmosphere, they are moving at speeds of several hundred km/s. If such a particle reaches Earth's upper atmosphere with a speed of 92 km/s, how fast was it moving when it cross

The gravitational attraction between an electron and a proton in a hydrogen atom is weaker than the coulomb attraction by a factor of about 10-40. An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound only by gravitational attraction.
