I believe the answer is A) Foot
Initia Velocity(u) :- 15m/s
Acceleration(a) :- 4m/s2
Time Taken(t) :- 50 Seconds
{ok a formula is there —->>> s = ut + 1/2 at2(it is ‘t’ square)….. now we will write like this and yeah don’t write this}
We Know,
s = ut + 1/2 at2
s = (15*50 + 1/2 *4*50*50)m
s= (750 + 5000)m
s = 5750 m
Therefore distance traveled is 5750 meters.
Hopefully this helps
Anthropology and sociology
The correct answer is D, white blood cells.
We know that red blood cells deliver nutrients and are not apart of the immune system; platelets are responsible for coagulation, which has nothing to do with the immune system, and plasma is a substance that, again, has nothing to do with immunity. White blood cells are the only things that fight disease (antibodies are white blood cells)!
I hope I helped!
