Answer:
763.94Wh
Explanation:
If the load is 120 watts running for 4 hours per night, the energy consumed is
120*4 =480 Wh
So, the energy gathered by the PV array is
E=480/(77%*96%*85%)=763.94Wh
The tension in the rope when this bucket is suspended but stationery (static) is equal to 400 Newton.
<u>Given the following data:</u>
Mass = 40 kg.
<h3>How to calculate the tension?</h3>
Mathematically, the tension in the rope when this bucket is suspended but stationery (static) can be calculated by using this formula:
T = m(a + g)
<u>Note:</u> Acceleration due to gravity (g) is equal to 10 m/s² while the acceleration is 0 m/s² because the bucket is stationery (static)
Substituting the parameters into the formula, we have;
T = 40(0 + 10)
T = 400 Newton.

Compression ring prevents pressurized refrigerant from blowing past the piston into the crankcase is the false statement.
Answer: Option A
<u>Explanation:</u>
Compression rings seal the combustion chamber from crankcase and then transfer heat to the cylinder from the piston. The piston rings are present in an internal combustion engine or steam engine with multi functions. The functions of piston rings are,
- Ensuring the combustion chamber is tightly sealed as to reduce the loss of gas to crankcase
.
- Promoting heat transfer from the piston to cylinder wall
.
- Controlling engine oil consumption
.
- Optimizing the proper quantity of oil between piston and cylinder wall.
To Find :
The torque of the stud.
Solution :
We know, torque can be calculated by force and distance between the center and force applied.
So,
Therefore, the torque on the stud is 20 N m .
