Here's what you need to know about waves:
Wavelength = (speed) / (frequency)
Now ... The question gives you the speed and the frequency,
but they're stated in unusual ways, with complicated numbers.
Frequency: How many each second ?
The thing that's making the waves is vibrating 47 times in 26.9 seconds.
Frequency = (47) / (46.9 s) = 1.747... per second. (1.747... Hz)
Speed: How far a point on a wave travels in 1 second.
The crest of one wave travels 4.16 meters in 13.7 seconds.
Speed = (4.16 m / 13.7 sec) = 0.304... m/s
Wavelength = (speed) / (frequency)
Wavelength = (0.304 m/s) / (1.747 Hz) = 0.174 meter per second
Henry Ford came up with the assembly line method to mass produce ford cars.
Answer:
0 J
Explanation:
Work = force × distance
Since the object isn't moved, the distance is 0. So the work is 0.
Answer:
1.44%
Explanation:
The potential energy of a spring is given by
The kinetic energy is
Now x = 12 A
Applying in the first equation
The percentage would be 14400%
at (makes more sense)
The percentage is 25 % of the kinetic energy
