Air flows from a reservoir in which the pressure is kept at 124 kPa through a convergent–divergent nozzle and exhausts to the

atmosphere where the pressure is 101.3 kPa. Under these conditions, the nozzle is choked and the flow is subsonic on both sides of the throat. To what value must the pressure in the reservoir be increased so that there is a normal shock on the nozzle exit plane?

A pendulum is swinging. It swings 85 complete swings and this takes 102 seconfs. What is the frequency? A. 0.83 Hz B.17Hz C.187
Serga [27]

Answer:

A: 0.83 Hz

Explanation:

Frequency can be calculated in a multitude of ways. The one way that is going to help you solve this problem is (# of times/seconds)

so you would divide 85 swings/102 seconds

= 5/6 or 0.8333 Hz

so your answer is A

Two blocks with different temperatures had entropies of 10 J/K and 30 J/K before they were brought in contact. What can you say
True [87]

Answer:

a. Ssystem  > 40 J/K

Explanation:

Given that

The entropy of first block = 10 J/K

The entropy of second block = 30 J/K

When two bodies come into contact with each other, the entropy of the combined system will increase and the entropy sum remains unchanged: According to the Second law of thermodynamics.The entropy of the system will be greater than 40  J/K.

Therefore the answer is a.

Ssystem  > 40 J/K
