I believe its the third answer
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 .
Answer:
B.
Explanation:
Given that a student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity A the height of the flight of stairs B the length of flight of stairs C the time taken to run up the stairs D the weight of the student
The rate of doing work is known as power.
Power = work done/time
Work done = energy = mgh
Since energy = mgh
Where mg = weight
And h = height
Time = time taken to run up the stairs.
Time, weight mg and height h will be needed while the Length of the flight is therefore not needed.
The correct answer is B.
Answer: When you touch wet canvas, surface tension will draw water to your finger. However, the drop left behind where you touched, like any irregular point on an overhead surface, will draw condensation from inside the tent if it is humid.
