A disk initially at rest is acted on by a constant net torque τ (think of this as force, F). The disk spins for a period of t seconds and rotates an angular distance of Δθ. The same disk is then brought to rest. The disk is now acted upon by a constant net torque 2τ (think of this as force, 2F). The disk spins for the same period of t seconds. What is the new angular distance the disk rotates?

The current in a hair dryer measures 11 amps. the resistance of the hair dryer is 12 ohms. what is the voltage?unit:

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?
