1. A circuit has a 1K ohm resistor. You need to temporally change the resistor value in the circuit to 200 ohms. What value of resistor would you place in parallel with the 1K ohm resistor to give you the total resistance of 200 ohms?

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

Asolid steel sphere (k=63.9 w m-1 k-1 , ? =7832 kg m-3 , c=0.523 kj kg-1 k-1 ), 100 mm in diameter is initially at a uniform temperature of 500o c and is suddenly quenched in a large oil bath for which t? = 100o c and h = 3200 w m-2 k-1. estimate the time required for the sphere to cool to 200o c and to 110o c
