An insulated piston–cylinder device initially contains 1 m3 of air at 120 kPa and 17°C. Air is now heated for 15 min by a 200-W

resistance heater placed inside the cylinder. The pressure of air is maintained constant during this process. Determine the entropy change of air, assuming: (a) constant specific heats. (b) variable specific heats.

Given a series of numbers as input, add them up until the input is 10 and print the total. Do not add the final 10. For example,
valentinak56 [21]

Answer:

22

Explanation:

The question talks about a given program to which you input a set of numbers. Once you input number 10, the program stops receiving inputs and adds the numbers you previously inputed, except for the final 10 which only works as a stopping signal. So, imagine you are working on the program and input the numbers 8, 3, 11 and 10 consecutively. Once you input the 10, the program immediately adds the previous numbers: 8+3+11=22.

So the output should be 22.

gulaghasi [49]

Answer:

The given blanks can be filled as given below

Voltmeter must be connected in parallel

Explanation:

A voltmeter is connected in parallel to measure the voltage drop across a resistor this is because in parallel connection, current is divided in each parallel branch and voltage remains same in parallel connections.

Therefore, in order to measure the same voltage across the voltmeter as that of the voltage drop across resistor, voltmeter must be connected in parallel.
