Answer:
Option B) This minimizes the harmful side effects of the radiations
Explanation:
Half-life is the time taken for the decay of an radio-active atom in which it disintegrates such that it becomes half of its value at the beginning.... The nuclei should be in active mode for a longer duration sufficient for the treatment of the condition but these nuclei should have a sufficient shorter half life so that they don't get enough time to cause any damage to the health of the person other than treating the cause.
A shorter half life gives the assurance that the radiation after the treatment will leave the body without getting accumulated and cause harm to the body cells and other organs.
Answer:200J
Explanation:E=MGH
= 2*10(assuming you round earth’s gravity to 10)*10
=200
The answer is the fourth choice because there are 7 represents in a coefficient.
Answer:
0 degrees
Explanation:
this is because when the light ray hits a surface a medium at 90 degrees then the angle of incidence = 0 , thus light doesn't bend when it enters the medium, no bending means angle of refraction is 0 degrees
