You have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. If the house circuit provides

120.0 volts, what is the current through this bulb?

This problem can be solved by manipulating the formula for power, which is: P = VI. Where:

P = Power in watts
V= Voltage in volts
I = Current in amperes

Since we are already given the power and voltage, simple substitution can be done.

P = VI
3.5 watts = 120 volts * I
I = 3.5 / 120
I = 0.0292 Amperes or 29.2 milliAmperes

Therefore, the current through the bulb is 29.2mA

I do not know how to draw this in full scale​
dezoksy [38]

Answer:

  use the actual dimensions on your drawing

Step-by-step explanation:

"Full scale" simply means you use the actual object dimensions on your drawing of it.

If you don't know the meaning of "plan view", "front elevation", or "side elevation," you may need to consult your curriculum materials or any of numerous references on mechanical drawing.

For this object, I would say a "front elevation" is the view from the point marked "Y". A "side elevation" is the view from the point marked "X". A plan view is the view from above.

__

If you draw, on paper, patterns for cutting out the pieces that make up the object, you will be well on your way to making the required drawings. For example, the face ABCPEF would represent the front elevation. (The only thing added on the drawing of it is a dashed line representing hidden line RQ 1 cm below line AB.)

The side elevation is the shape of AQHGF on top of the shape EMLD. On your drawing of it, the line for EM is the same line as the line representing FG.

The top (plan) view is the shape CPNK with lines in the appropriate places to represent the edges EM, FG, and RQ.

__

Orthogonal views of an object like this are different from the kind of drawing you would make if you were trying to make a "net" for folding or calculating surface area. A net has every face actual size. Here, every face is represented the way it would be seen from a given direction. Slanted faces never show up actual size.

Root of 6x^2 -8 = -8x
Svetlanka [38]

Answer:

If your question is set up like this \sqrt{6x^2-8}=-8x then your answer is No solution.

If your question is set up like this\sqrt{6x^2}-8=-8x then your answer is x=\frac{4(8-\sqrt{6}) }{29} or x = 0.765

Hope this helps!
