A car starts from rest and accelerates uniformly for a distance of 160 m over an 8.0-second time interval. The car's acceleration is
(A) 0.05 m/s
(B) 0.05 m/s/s
(C) 5 m/s/s
(D) 20 m/s
(E) 20 m/s/s

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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.
