Suppose we have an infinitely long wire carrying a current of 2.0 A. It is bent into an L-shape extending into positive infinities along the x- and y- axes. Find the magnitude of the magnetic field at a point P with coordinates (0.2 m, 0.2 m). B

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
