Answer:
full load current = 7.891151 A
so correct option is b. Ir= 7.89
Explanation:
given data
Energy E = V = 240 V
frequency = 60 Hz
full-load slip = 0.02
full-load speed = 1764 rpm
winding resistance = 0.6 Ω
winding reactance = 5 Ω
to find out
rotor current at full-load
solution
we will apply here full load current formula that is express as
full load current = ...................1
here S is full-load slip and E is energy given and R is winding resistance and X is winding reactance
put here value we get
full load current =
full load current = 7.891151 A
so correct option is b. Ir= 7.89
Never operate electric tools outdoors or in wet conditions unless the circuit is protected by a ground fault circuit interrupter (GFCI).
<h3>What is a circuit?</h3>
When a number of electric entities are connected through various conductors is called a circuit.
Here,
A ground fault circuit interrupter (GFCI) helps to avoid the repercussion caused due to electric shocks. An individual receives a shock, the GFCI perceives this and cuts off the current before the individual can get any damage. it is usually installed where electrical circuits come into reference with water.
Thus, Never operate electric tools outdoors or in wet conditions unless the circuit is protected by a ground fault circuit interrupter (GFCI).

Answer:
Resistance of copper = 1.54 * 10^18 Ohms
Explanation:
<u>Given the following data;</u>
Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m
Resistivity, P = 1.7 * 10^8 Ωm
Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m
Radius = 0.000325 m
To find the resistance;
Mathematically, resistance is given by the formula;
Where;
- P is the resistivity of the material.
- L is the length of the material.
- A is the cross-sectional area of the material.
First of all, we would find the cross-sectional area of copper.
Area of circle = πr²
Substituting into the equation, we have;
Area = 3.142 * (0.000325)²
Area = 3.142 * 1.05625 × 10^-7
Area = 3.32 × 10^-7 m²
Now, to find the resistance of copper;
<em>Resistance = 1.54 * 10^18 Ohms </em>
An irrigation fluid that is used for endoscopic procedures using monopolar electrosurgery is Glycine 1.5% solution.
<h3>What is an irrigation fluid?</h3>
This is a fluid that is used for dilation during the process of endoscopic surgery.
What the fluid does is that it helps to wash away dirt from the operating area after it has dilated the area.

Answer:
the restraining forces in the x and y-directions are :
Explanation:
From the given information;
Let us first calculate the outlet velocity by using continuity equation.
where;
= inlet diameter = 6 - In
outlet diameter = 4 -In
inlet velocity
outlet velocity = ???
to In; we have
Since 1 ft = 12 inches; thus
12.375 ft/s = (12.375 × 12 ) inches = 148.5 In/s
5.5 ft/s = 66 In/s
By using the linear momentum in x-direction for the volume ; we have the relation:
where;
Therefore; the restraining forces in the x and y-directions are :
