Ablock of mass 10.1kg rests on a slope an angle of 43.9∘ relative to the horizontal. what is the size of the force parallel to the slope, in newtons? use a gravitational acceleration value of g = 9.8m/s^2.

What are the necessary conditions for fusion?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
