Answer:
(D) 2.55 eV is absorbed
Explanation:
For an electron located in an inner orbit to jump an upper orbit, it needs an energy equal to the difference between the two quantized orbits. This energy comes from the absorption of a photon with the same energy required. The formula for the energy levels of a Hydrogen atom is:
where is the energy of the ground state and n is the energy level or state. Finding and :
Finally we find the energy difference between n=4 and n=2 state:
Answer:
13.6565mm of Hg
Explanation:
We only need to use the from Hagen poiseuille equation to be able to find the pressure change. That is
Once the equation is defined, we clear based on the pressure and replace
Finally we have,
Answer:
The answer is 10.857mJ
Explanation:
The energy stored in this solenoid is given by the below mentioned equation,
where L the inductance of this solenoid is given by the below mentioned equation,
Plugging this into the energy equation you obtain the equation for the total energy stored in the magnetic field of the solenoid, given by,
where is the permeability of free space which equals to . Plugging all the quantities into the above equation from the data in the question after converting to standard units. of meters instead of centimeters, we get for the energy stored in the coil,

There are things like comets, asteroids, meteoroids, satellites, planets, etc. move around the sun.
Explanation:
- The solar system is made up of not only planets and its satellites, but there are also other things which move around the sun.
- Those are like comets, asteroids, and meteoroids.
- Asteroids are also called mini planets, there are bigger ones too and they are called planetoids. The orbit the sun in their belt called asteroid belt situated in between the orbits of Mars and Jupiter.
- Comets appear like snowballs which contain frozen gases, dust and rock which orbits the sun.
- Meteoroids are the metallic or rocky body found the outer space. It is smaller than the asteroids and micro-scale meteoroids are the space dust.
