Answer:
18.4 s
Explanation:
The time constant of an RC circuit is given by
where
R is the resistance
C is the capacitance
For the first circuit we have
So we can find the capacitance
Now in the second circuit, the new resistance is
So the new time constant will be
A = Vf - Vi / t
A = 26m/s - 12 m/s / 14 s
A = 14 m/s / 14 s
A = 1 m
Answer:
In constructive interference, a crest meets a crest or a trough meets a trough, resulting in a larger crest or trough.
In destructive interference, a crest meets a trough and results in cancellation hence a smaller disturbance than either of the two interacting waves.
(a). By the inertia, it's difficult to stop heavier mass than lighter mass.
As, moment of inertia is directly proportional to the mass of the body.
Thus, more force is required to stop the boy with heavier mass than lighter mass.
The problem statement for the given case is,
The time taken by the heavier body to stop swinging is more than the lighter body, then what is the impact of weight on the time period of the swing?
