Answer:

Explanation:
Due to the law of conservation of energy, the energy of the emitted X-ray photon is equal to the energy lost by the electron.
The initial kinetic energy of the electron is:

The electrons decelerates to 3/4 of its speed, so the new speed is

So the final kinetic energy is

So, the energy lost by the electron, which is equal to the energy of the emitted photon, is

The wavelength of the photon is related to its energy by

where h is the Planck constant and c the speed of light. Substituting E, we find

The magnitude (in N) of the electric force that one particle exerts on the other is A. F=107.6nN.
F=[(9×10^9) ×(7.10×10^-9) ×(4.42×10^-9)] /(1.62^2)
F=(282.4×10^-9)/2.6244
F=107.6×10^-9N
F=107.6nN
Experiments with electric charges have shown that two charged objects exert electrical forces on each other. The magnitude of the force is linearly proportional to the net charge of each object and inversely proportional to the square of the distance between the objects.
Coulomb's law for calculating electrostatic forces. This force arises from the interaction between two charged objects (or point charges), the magnitude of which is calculated by F = kQ1Q2r2 F = k Q 1 Q 2 r2.

Answer:
They gain kinetic energy
Explanation:
When the temperature of the particles in a substance rise, its internal energy increases. This internal energy is thus translated to kinetic energy of the particles in the substance. If the substance is a solid, as the kinetic energy increases, the vibrations of the particles of the substance increases causing it to undergo a change of state to liquid when the temperature reaches its melting point.
This change of state also occurs from the liquid state to the gaseous state as the internal energy of the substance, and thus the kinetic energy of the particles increase when the temperature reaches the substance's boiling point.
<u>So, as the temperature of a substance rises, the particles of the substance gain kinetic energy.</u>
Answer:
In physics, a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body. In its original concept, gravity was a force between point masses. Please give me the brainiest answer?

Answer:
A bag of blood with a density of 1050 kg/m4 is raised about 1.00 m higher than the level of a patient's arm. How much greater is the blood pressure at the patient's arm than it would be if the bag were at the same height as the army is the solisan of kind
