Consider a flow of air with a free stream velocity of 10 m/sec and a free stream temperature of 20 degree C over a flat plate with a constant surface temperature of 80 degree C. The average heat transfer coefficient for this problem

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
