A child applies a torque of 1200 N*M to a merry go round. The rotational interia of the merry go round is 900 kg*m 2.
1. What is the net torque acting on the merry go round.
2. What is the angular acceleration of the merry go round?
3. If the merry go round starts from rest, what will its angular acceleration be after 5 sec?
4. What will its angular velocity be after 5 seconds?
5. What will its angualr displacement be afer 5 seconds?
The potential difference between two points in a wire 10 m apart is 12 V. When the current density is 4*10^7 A/m^2. find the resistivity of the material in the wire
At rest when constructed, the ring is set rotating about its axis so that the people inside experience effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the r..
If the loop is placed in a uniform magnetic field of magnitude 0.200 T, illustrate what is the maximum torque that can act on it? The resistivity of copper is 1.7 multiplied by 10-8 · m.
