Answer:
Ratio of length will be
Explanation:
We have given time period of the pendulum when length is is
And when length is time period
We know that time period is given by
So ----eqn 1
And -------eqn 2
Dividing eqn 2 by eqn 1
Squaring both side
Answer:
-0.8 m/s²
Explanation:
Acceleration is the slope of a velocity vs. time graph.
a = Δv / Δt
a = (0 m/s − 12 m/s) / (15 s − 0 s)
a = -0.8 m/s²
