i think it's Basel Metabolism
What are the devices I don’t see any on there
Explanation:
It is given that, a mass attached to a spring oscillates and completes 53 full cycles in 28 s. Frequency of the system is given by the number of oscillations or vibrations per second. Here, the frequency of this system is given by :
f = 1.89 Hertz
The relationship between the frequency and the time period of the spring is inverse i.e.
T = 0.52 seconds
Hence, this is the required solution.
A) Water is moving from a point of bigger height to a point of a lower height, This changes the kinetic and potential energies of water. Some of the kinetic energy of water is transfered to a waterwheel. This causes water wheel to spin. Spining waterwheel has rotational energy. Also waterwheel is rotating around certain point. This causes friction and there is frictional energy.
B)To light LED we need electric energy. To create electric energy we need a generator. Generator consists of a rotor (a magnet) and a stator (copper wire). If we attach a magnet to waterwheel and a wire somewhere close to waterwheel the electric energy would be induced. This energy can be used to light LED.
We have that the Average Force is given
Avg F=2.0488N

Generally the equation for the Mean is mathematically given as
For Mass
For Acceleration
Since Average Acceleration and mass are found above
Therefore
The Average Force is given as
