40 POINTS IF ANSERED WITHIN 10 MINS what are two benefits of scientists using a diagram to model the water cycle A It can Show changes that Occur in many Diffrent parts of Earth at The Same Time . B It can Be Used to Show How the parts of the cycle relate to One Another. C Only a Few Factors In The Water Cycle can be shown on the Diagram .D It can be used to show as much detail as is Present in The actual Water Cycle.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i. e., a violation of one statement leads to the violatio the other statement)

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
