Answer:
The acceleration due to gravity at Pluto is 0.0597 m/s^2.
Explanation:
Length, L = 1 m
10 oscillations in 257 seconds
Time period, T = 257/10 = 25.7 s
Let the acceleration due to gravity is g.
Use the formula of time period of simple pendulum

Answer:
Explanation:
A general wave function is given by:

A: amplitude of the wave = 0.075m
k: wave number
w: angular frequency
a) You use the following expressions for the calculation of k, w, T and λ:



b) Hence, the wave function is:

c) for x=3m you have:

d) the speed of the medium:

you can see the velocity of the medium for example for x = 0:

Answer:
9213 J
Explanation:
Change in Kinetic energy = Change in Potential energy
= 12,928J - 3715J
=9213 J

Answer:
the flywheel's average angular acceleration is -2.05 rad/s²
Explanation:
<u>Note:</u> counterclockwise is positive
clockwise is negative
Given;
initial angular velocity,
= 5.03 rev/s = 
final angular velocity,
= -2.63 rev/s = 
duration of the flywheel rotation, Δt = 23.5 s
The average acceleration of the flywheel is calculated as;

Therefore, the flywheel's average angular acceleration is -2.05 rad/s²
