Answer:
t = 12.82s
Explanation:
F = m×a
= (70)×(2)
= 140 N
during the acceleration, the sprinter cover d = 29 m with time:
d = 1/2×at
29 = 1/2×(2)×t^2
t^2 = 29s
t = 5.39s
and attains the velocity of:
v = a×t
= 2×5.39
= 10.77 m/s
Then,to cover the last x = 80 m with a speed of 10.77 m/s in time:
t = x/v
= 80/10.77
= 7.43s
Therefore, it will take the sprinter 7.43 + 5.39 = 12.82s
Answer:
Electrons are so small that it does not affect the mass of atom .
Explanation:
Electrons are much smaller in mass than protons, weighing only 9.11 × 10^-28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element's overall atomic mass.
It is b 9.1 :) have a nice day
