150 lb of force is applied at the end of a shaft that is 2 1/2 ft long. It is applied

at an angle of 90° to the lever. How much torque is produced? If the shaft is

rotating at 350 rpm, what is the power?

Explain how you could transmit two independent base-band information signals by using SSB on a common carrier frequency.

What event causes the formation of trenches in Earth's crust

You are wearing skates and standing on a frictionless ice rink. Strapped to your back is jet pack that can produce a constant horizontal force of 75 lbf = 334 N. If you switch on the jet pack, what is your speed after 5 seconds?

You have a hose connected to a water outlet, a 5 gallon can and a 3 gallon can. I need exactly 4 gallons of water for my lobster stew. How can you deliver exactly 4 gallons?

A model of a submarine, 1 : 15 scale, is to be tested at 180 ft/s in a wind tunnel with standard sea-level air, while the prototype will be operated in seawater. Determine the speed of the prototype to ensure Reynolds number similarity

A piston-cylinder assembly contains 5 kg of air, initially at 2.0 bar, 30 C. The air undergoes a process to a state where the pressure is 2 bar, during which the pressure-volume relationship is pV1.5 = constant. Assume ideal gas behavior for the air.

Who is responsible for making sure that PPE fits each worker properly? A) employee B) employer

This method will sell the seat in row i and column j unless it is already sold. A ticket is sold if the price of that seat in the array is 0.

A low-temperature physicist wishes to publish his experimental result that the heat capacity of a nonmagnetic dielectric material between 0.05K and 0.5K varies as A√ T + BT^3 As editor of the journaL should you accept the paper for publication?

Consider an electric motor with a shaft power output of 20 kW and an efficiency of 88 percent. Determine the rate at which the motor dissipates heat to the room it is in when the motor operates at full load.
