Sorry for the late answer, just came across this.
Answer:
The magnetic force can act from a distance because of the magnetic field that is created around it. It can be defined as imaginary lines around the magnet upto which it has magnetic force.
If a piece of iron is put into the magnetic field but has a slight distance from the magnet, it will be pulled towards the magnet because it is in its magnetic field.
The south pole and the north poles of the magnet has effect on each other. Same poles repeal each other and opposite poles attract each other resulting in forming a field of attraction or repulsion.
The imaginary lines created are known as magnetic field which is responsible for the magnetic force from a distance.

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.
