Gaining electron makes it “negative”
Answer:
5.76N
Explanation:
We are given that
Distance between two charges ,
Electrostatic force=
Where k=
Substitute the values then we get
Hence, the electric force between two charges=5.76N
Answer:
The net effect on the laboratory is cooling of the space.
Explanation:
Given:
power used by the air conditioner,
coefficient of performance,
We know that:
<u>Therefore the cooling power capacity:</u>
The net effect on the laboratory is cooling of the space.
Answer:
D. radiation dose
Explanation:
The amount of energy transferred to electrons by ionizing radiation is the basis of the concept of <u>Radiation dose</u>. Radiation dose, also known as absorbed radiation dose, is the amount of energy deposited in a given mass of a medium by ionizing radiation. The international system of units (SI system) for Radiation absorbed dose and effective dose in radiation measurement are "gray" (Gy) and "sievert" (Sv), respectively.
