For heat transfer purposes a standing man can be modeled as a 32 cm diameter, 159 cm long vertical cylinder with both top and bottom surfaces insulated and with the side surface at an average temperature of 34 degrees c. for a convection heat transfer coefficient of 20 w/m^2, determine the rate of heat loss from this man by convection in an environment at 25 degrees c.

In the first law of thermodynamics, triangle e=q-w, what does q stand for

How would a small bar magnet be oriented when placed at position x?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
