Answer:
The temperature of star is 5473.87 K
Explanation:
Given:
Energy difference eV
The ratio of number of particle
Degeneracy ratio
From the formula of boltzmann distribution for population levels,
Where boltzmann constant =
K
Therefore, the temperature of star is 5473.87 K
The frequency of the wave is 50 Hz
Explanation:
The frequency of the wave is defined as the number of cycles per second of the wave:
where
N is the number of cycles completed in a time t.
Frequency is measured in Hertz (Hz).
In this problems, the wave has
N = 100 pulses
in
t = 2.0 s
Therefore, its frequency is

Answer:
The kinetic energy is
Explanation:
From the question we are told that
The radius of the orbit is
The gravitational force is
The kinetic energy of the satellite is mathematically represented as
where v is the speed of the satellite which is mathematically represented as
=>
substituting this into the equation
Now the gravitational force of the planet is mathematically represented as
Where M is the mass of the planet and m is the mass of the satellite
Now looking at the formula for KE we see that we can represent it as
=>
substituting values
