Well if Block A is on top of Block B, then the total mass is the sum of Block A and Block B. Therefore the total mass is 16kg. Since the blocks are not moving, the force of gravity is equal to the normal force.
The energy-level change occurs as the atom is absorbs a 2.03-eV photon.
<h3>
Energy change of the mercury atom</h3>
The energy change of the mercury atom is calculated as follows;
Energy emitted by a photon when it falls from level b to energy level e is calculated as follows;
ΔE = -3.71 eV - (-5.74 eV)
ΔE = -3.71 eV + 5.74 eV
ΔE = 2.03 eV
When electron jumps from lower energy level to higher energy level, energy is absorbed, thus, the energy-level change occurs as the atom is absorbs a 2.03-eV photon.

Frequency, , is defined as the rate of rotation, or the number of rotations in some unit of time. Angular frequency, , is the rotation rate measured in radians. These three quantities are related by f = 1 T = ω 2 π .
Answer:
Explanation:
While pure science deals with knowledge discovery Applied science deals with knowledge use
Answer: Microwaves.
Explanation: First, we have a trivial answer, and that is the visible light, which is responsible to let the information on the tv to be seen by the user.
Now, TV technology was possible thanks to the microwaves, that are used because these can carry more energy than other types, and these microwaves needed a special technology because they couldn't be handled by the current technology at the time.
