the answer would be false
hope I helped and goodluck
:)
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 .
All particles have energy, and the energy varies depending on the temperature the sample of matter is in, which determines if the substance is a solid, liquid, or gas. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy
Answer:
E = 1440 kJ
Explanation:
It is given that,
Power of a cooker oven is 800 W
Voltage at which it is operated is 230 V
Time, t = 30 minutes = 1800 seconds
We need to find the electrical energy used by the cooker oven. The product of power and time is equal to the energy consumed. So,
So, electrical energy of 1440 kJ is consumed by the cooker oven.
The answer is C because if it’s moving with a constant speed it’s gonna be balanced and there will be no force
