A proton is located at the point (x = 1.0 nm, y = 0.0 nm) and an electron is located at the point (x = 0.0 nm, y = 4.0 nm). Find
OLga [1]

Answer:

C : 1.4*10^(-11) N.

Explanation:

q_1 = q_2 = 1.6 * 10^(-19)

R^2 = (1)^2 + (4)^2 = 1.7 * 10^(-17) m^2

The coulomb's law is as follows:

F_e = k*q_1*q_2 / R^2

F_e = k*q^2 / R^2

F_e = (9.0*10^9) * (1.6 * 10^(-19))^2 / 1.7 * 10^(-17)

F_e = 1.35 * 10^(-11) N

Hence, answer closes to obtained is option C : 1.4*10^(-11) N.

Both cats transfer energy to their surrounding environment because of radiation type of movement.

<h3>How both cats transfer energy to their surroundings when they are outside on a cold day?</h3>

A cat X and cat Y transfer energy to their surroundings due to radiation because the heat energy that is present inside them is emitted in the form of radiation.

So we can conclude that both cats transfer energy to their surrounding environment because of radiation type of movement.
