Calculate the rotational inertia of a wheel that has akinetic

Physics
1 answer:
andrew11 [14]3 years ago
4 0

Answer:

J = 14.4 kg*m^2

Explanation:

Assuming that the wheel is not moving anywhere, and the kinetic energy is only due to rotation:

Ek = 1/2 * J * w^2

J = 2 * Ek / (w^2)

We need the angular speed in rad / s

566 rev/min * (1 min/ 60 s) * (2π rad / rev) = 58.22 rad/s

Then:

J = 2 * 24400 / (58.22^2) = 14.4 kg*m^2

Lena [83]

Answer:

Only 2,3,4 are true

Explanation:

Bosons Particles are particles that condense to the same state. Bosons particle have integral spin like 0 , $\hbar$, 2$\hbar, 3$\hbar$, etc. Bosons particles always have asymmetric wave function and there is exchange of particles.

1) It does not obey Fermi_ Dirac statistics

2) It obeys Bose-Einstein statistics

3) The object can have intrinsic spin 2$\hbar

4) Yes the Bosons particle is always symmetric with exchange of particles

5) No Bosons particle are symmetric and not asymmetric

Light is an oscillating magnetic field alone. an oscillating electric field alone. electric and magnetic fields that oscillate p
cupoosta [38]

Explanation:

  • As light is an electromagnetic wave that causes sensation of sight.  
  • Every electromagnetic wave has electrical and magnetic components in it which are perpendicular to the direction of propagation of wave.  
  • The electrical and magnetic components are mutually perpendicular to each other in an electromagnetic wave.
  • The speed of light in vacuum is c=3\times 10^{8}\ m.s^{-1}, which decreases when it passes through a matter (precisely a transparent medium) which allows the passage of light through it. When the light passes through some transparent matter then its speed decreases as compared to the speed of light in vacuum.

Which quantity can be calculated using Newton’s second law of motion?
DiKsa [7]

Newton's 2nd law of motion:

          Net Force  =  (mass) x (acceleration) .

The law shows the relationship among an object's mass
and acceleration, and the net force acting on it.

If you know any two of the quantities in the formula,
the law can be used to calculate the third one.
