Afan rotating with an initial angular velocity of 1000 rev/min is switched off. in 2 seconds, the angular velocity decreases to 200 rev/min. assuming the angular acceleration is constant, how many revolutions does the blade undergo during this time?

State the right hand rule of the direction of magnetic field in a conductor carrying current

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
