Answer:
Frequency, f = 15 Hz
Explanation:
We have,
Speed of an ocean wave is 45 m/s
Wavelength of a wave is 3 m
It is required to find the frequency of an ocean wave.
Speed of a wave,
, f = frequency of ocean wave
![f=\dfrac{v}{\lambda}\\\\f=\dfrac{45}{3}\\\\f=15\ Hz](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7Bv%7D%7B%5Clambda%7D%5C%5C%5C%5Cf%3D%5Cdfrac%7B45%7D%7B3%7D%5C%5C%5C%5Cf%3D15%5C%20Hz)
So, the frequency of an ocean wave is 15 Hz.
2.5 kg because you cant change the weight of the rock
Answer:
11700j
Explanation:
add the two because the plate has to maintain the temp.
2700+9000=11700

Explanation:
When you run, your body has a kinetic energy and when you fall while running, the friction between the carpet and your foot, transforms the kinetic energy into thermal energy or heat energy. This can even cause, real burn if the skin were too hot.
