Three quarters remain un-decayed
To solve this problem we will apply the concepts related to the calculation of power, from the two electrical forms:


Here,
V = Voltage
I = Current
R= Resistance
P = Power
PART A)

Replacing,


Resistance of bulb is 
PART B)



The bulb will draw 1.25A current
Answer:
P = 11666.6 W
Explanation:
Given that,
Work done by the motor, W = 3500 kJ
Time, t = 5 min = 300 s
We need to find the power developed by the motor. Power developed is given by :

So, the required power is 11666.6 W.
Answer:
Scientists believe that light is made of waves because experiments have shown that, based on Huygens's principle, waves have the ability to bend and change direction.
Explanation:
Answer:
Shania is correct because a fulcrum is the lower part of a lever and a pivot is not part.
