Answer:
By looking at the graph it looks like its decreasing but you may want to re- read the question to make sure that I am correct.I hope that this helps!
Explanation:
Answer:
1.4 * 10 ^-1 Ω
Explanation:
Hi,
For this question, we gotta use the formula
R = pL/A
p = The resistivity of your material at 20°C
L = length of the wire
A = cross-sectional area
The resistivity of tungsten is 5.60 * 10^-8 at 20°C
By plugging the values, we get:
R = (5.60 * 10^-8)(2.0)/(7.9*10^-7) = 1.4 * 10 ^-1 Ω
Answer:
9.8 m/s^2
Explanation:
This is a constant that you should memorize
A step-down transformer has more loops in : A. Primary coil
Primary coil refers to the coil to which alternating voltage is supplied. It's usually connected to the AC supply

Answer:
12.75 A
Explanation:
The total power is 300 + 30 + 960 + 2 × 120 = 1530 W
Electrical power is given by
Then
With a voltage of 120 V,
