The answer is B. You divide 717 by the acceleration by gravity of earth (9.8 m/s) and divide 5320 by your answer.
"Circulatory system" does that, as all about transportation of blood within the body comes under it's work
Hope this helps!
Acceleration due to gravity is about 9.8 m/s²
So after every second, the speed increase by 9.8 m/s
After 1 second, the object would fall at a speed of 9.8 m/s
After 2 seconds the object would fall at a speed of 19.6 m/s
So after 4 seconds, the object is going to be at a speed of:
9.8 x 4 = 39.2 m/s

<u>Answer</u>
39.2 m/s
Protons and neutrons are in the center of the atom, making up the nucleus. The proton and electron are exactly the same size but different,Since the difference charges attract, protons and electrons attract each other.
