Yes,it’s an object because it’s solid I think...
They are called fixed and movable pulleys
One formula for power is
P = (voltage squared)/(resistance).
Resistance of 3 equal resistors in parallel is 1/3 of the value = 100/3 ohms.
Power = (40^2)/ (100/3)
. = (1600 • 3) / (100)
. =. 48 watts .
Since the angle is West of North, therefore to find for
the westward component (horizontal component) of the vector, we use the sin
function:
sin θ = opposite side / hypotenuse = westward component /
resultant vector
So the westward component (x) is:
x = 85.42 sin 23
<span>x = 33.38 unit</span>
