Answer: The acceleration due to gravity is the constant pull towards the core of the earth due to gravity on earth. It is abbreviated by the letter g and is equal to -9.81 m/s².
Explanation:
displacement is the shortest distance travelled...
hence in this case the displacement will simply be 12m
Explanation:
Use half life equation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is time,
and T is half life.
0.375 = 3 (½)^(1 / T)
0.125 = (½)^(1 / T)
(½)^3 = (½)^(1 / T)
3 = 1 / T
T = 1/3 hours
T = 20 minutes
