<h2>
Answer:</h2>
24Ω
<h2>
Explanation:</h2>
When resistors are connected in parallel, the reciprocal of their combined resistance, when read with a DMM (Digital Multimeter - for measuring various properties of a circuit or circuit element such as resistance...) is the sum of the reciprocals of their individual resistances.
For example if two resistors of resistances R₁ and R₂ are connected together in parallel, the reciprocal of their combined resistance Rₓ is given by;
= 
+ 
Solving for Rₓ gives;
= 
------------------(i)
From the question;
Let
R₁ = resistance of first resistor = 40Ω
R₂ = resistance of second resistor = 60Ω
Now,
To get their combined or total resistance, Rₓ, substitute these values into equation (i) as follows;
= 
= 
= 24 Ω
Therefore, the total resistance is 24Ω
Answer:
Tire inflation can be caused by temperature and speed :)
Explanation:
The wind is an actual form of solar energy. winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities. The wind is capture in a wind turbine which provides a renewable energy source, the wind makes the rotor spin, as the rotor spins the movement of the blades drives a generator that creates energy, also known as wind power. The average wind efficiency of turbines is between 35-45%.
Advantages of wind power
- Wind power is cost-effective
- wind creates jobs
- wind enables US industry growth and US competitiveness
-it's a clean fuel source
Answer:
Explanation:
In the development of a torsion formula for a circular shaft, the following assumptions are made: Material of the shaft is homogeneous throughout the length of the shaft. Shaft is straight and of uniform circular cross section over its length. Torsion is constant along the length of the shaft.
Answer:
initial quality = 0.3690
heat transfer = 979.63 kJ/kg
Explanation:
Given data:
volume of tank 0.45^3
weight of water 12 kg
Initial pressure 20 bar
final pressure 4 bar
Specific volume 
At Pressure = 20 bar, from saturated water table
inital quality is x =0.3690
Heat transfer is calculated as
from saturated water table, for pressure 20 bar ,
=908.79 + 0.0357(1890.7)
= 979.63 kJ/kg
