The moment of inertia of the flywheel is 2.63 kg-m^{2}

It is given that,

The maximum energy stored on the flywheel is given as

E=3.7MJ= 3.7×10^{6} J

Angular velocity of the flywheel is 16000\frac{rev}{min} = 1675.51\frac{rad}{sec}

So to find the moment of inertia of the flywheel. The energy of a flywheel in rotational kinematics is given by :

E = \frac{1}{2}Iw^{2}

By rearranging the equation:

I = \frac{2E}{w_{2} }

I = 2.63 kg-m^{2}

Thus the moment of inertia of the flywheel is 2.63 kg-m^{2}.

What is the resultant of the vecotors shown?
Karolina [17]

D, I believe would be the first minus the second vector.

To solve this I named the first vector as A and the second as B.

So... vector A - B = resultant

or A + (-B)

A negative indicates a direction of a vector so if we flip the direction the other way we have the first vector (A) pointing vertically upwards and then vector B pointing to the west.

Now we have to use the head to tail method, meaning that the head of the first vector has to connect with the tail of the other vector added.

So we should have something like this

(-B)  < -  -  - -  ^

                      |

                      |  (A)

                      |

To add these two vectors, technically A - B, draw a line from the tail of A to the head of -B which would look like image D.

Hope this helped!

Why do scientists believe that light is made of streams of particles?
Talja [164]

Scientists believe that light is made of streams of particles because light exhibits the particle nature. This can be explained on the basis of photoelectric effect observed when light is made to fall on the surface of a metal. when light falls on the surface of a metal, it makes the electron to eject out. This is possible only when light consists of small particle called photons. hence the scientists believe that light is made of streams of particles.
