A long nonconducting cylinder (radius = 11 cm) has a charge of uniform density (5.0 nC/m3) distributed throughout its volume. Use Gauss law to determine the magnitude of the electric field 15 cm from the axis of the cylinder. Show all the major physics steps including the detailed

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
