Answer:
20.35m per minute
Or
1,221.43 per hour
100/5=20
200/7= 28.57
50/4= 12.5
20+28.57+12.5= 61.07
61.07/3= 20.35m per minute
Or
20.35 x 60= 1,221.43m per hour
Answer:
0.248 m
Explanation:
The period of a simple pendulum is given by
where
L is the length of the pendulum
g is the acceleration of gravity
The pendulum in the problem passes its lowest point twice every second: this means: this means that it makes one complete oscillation in one second, so its period is 1 second:
T = 1 s
And using
We can rearrange the equation above to find L, the length of the pendulum:
Answer:
hydraulic lift pump moves the lift piston out in a series of movements. and a hydraulic brake moves it out in one short break.
The answer is b because kinetic energy is the energy of motion, while potential energy is the energy stored in an object because of its position.
