...the potential energy that you build while going up the hill on the roller coaster could be let go as kinetic energy -- the energy of motion that takes you down the hill of the roller coaster.
I assume that the force of 20 N is applied along the direction of motion and was applied for the whole 6 meters, the formula of work is this; Work = force * distance * cosθ where θ is zero degrees. Plugging in the data to the formula; Work = 20 N * 6 m * cos 0º.
Work = 20 N * 6 m * 1
Work = 120 Nm
Work = 120 joules
Hope this helps!
The speed of sound on planet is 210 m/s.

What is Oscillation?</h3>
Oscillation is the repeating or periodic change of a quantity around a central value or between two or more states, often in time. Alternating current and a swinging pendulum are two common examples of oscillation.
There are 3 main types of Oscillation –
- Free
- damped
- forced oscillation
f = frequency = 600 Hz
lambda = wavelength = 35 cm = 0.35 m
Now,
V = speed = f × lambda = 210 m/s
Hence, speed of sound on planet is 210 m/s.

Silt and other wash can accumulate behind the motor and if other boats are added they can get their hulls damaged or scraped then, depending on the size of the material. It can also cause trailers to get stuck if they drive into the place from where the boat came.
Answer:
Time period is directly proportional to the length so if the length is doubled the time period is doubled
hope it is helpful....
