Substitution is The answer
A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow
T = D/V, where D = distance, V = tangential velocity.
Answer:True
Explanation:
We know that frequency in a tight string is given by
where 
and velocity is given by
As 
increases v also increase but wavelength 
remain same because ends of string are fixed.
Answer:
45.09 m/s^2
Explanation:
from the question we were given the following parameters
mass = 931.9 kg
initial velocity (V1) = 0 m/s ( since it started from rest )
final velocity (V2) = 25.7 m/s
time (t) = 0.57 s
The average acceleration is given by:
a = ( V2 - V1 ) / t
therefore
a = (25.7 - 0) / 0.57 = 45.09 m/s^2
