Two forces and are applied to an object whose mass is 8.0 kg. The larger force is . When both forces point due east, the object’s acceleration has a magnitude of . However, when points due east and points due west, the acceleration is , due east. Find (a) the magnitude of and (b) the magnitude of . F ⃗ A F ⃗ B F ⃗ A 0.50 m/s2 F ⃗ A F ⃗ B 0.40 m/s2 F ⃗ A F ⃗

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

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
