Answer:
A photon of wavelength 103 nm is released
Explanation:
When an electron in an atom jumps from a higher energy level to a lower energy level, it releases a photon whose energy is equal to the difference in energy between the two levels.
For example, if we are talking about a hydrogen atom, the energy of the levels are:
So, the energy of the photon released when the electron jumps from the level n=3 to n=1 is
In Joules,
We can also find the wavelength of this photon, using the equation:
Answer:
D. 2.5 m
Explanation:
1.5 m up to the beam + 0.5 m up + 0.5 m down = 2.5 m total
When the pendulum and roller coaster move to the top, its has more potential energy whereas when comes to the bottom has more kinetic energy.
<h3>Compare and contrast the energy transfer of a roller coaster to that of a pendulum:</h3><h3>What is the transfer of energy in a roller coaster?</h3>
The transfer of potential energy to kinetic energy occur when the roller coaster move along the track. As the motor pulls the cars to the top, the body has more potential energy whereas when the body comes to the bottom , it has kinetic energy in the object.
<h3>What is the energy transfer in a pendulum?</h3>
As a pendulum swings, its potential energy changes to kinetic energy and kinetic energy changes into potential energy. At the top more potential energy is present.
So we can conclude that When the pendulum and roller coaster move to the top, its has more potential energy whereas when comes to the bottom has more kinetic energy.

The correct answer is no, the dew point will not be reached. The dew point would also fall with the temperature, but at a lesser degree of decline.
From newtons second law of motion,
F=ma hence,
F=20N
m=5kg so,
20=5×a
a=4m/s^2
