Hello!
A portable DVD player requires six 1.5-volt batteries to operate. If the resistance in the circuit is 7.2 ohms, what is the current?
Data:
We have six 1.5 volt batteries, soon, your tension (V)
V = 1.5 * 6 = 9 Volts
R (resistance) = 7.2 ohms
I (Current intensity) = ? (in Amps)
Solving (Ohm's First Law):
Answer:
The current is 1.25 amps

Answer:
Explanation:
Given:
ΔT
So the power the air conditioner do first determine the heat that removed
Now that heat in the time the air take to remove the heat
Finally that power drawn can be find by the power and the COP is knowing
Answer:
Green light
Explanation:
The thickness of oil is smaller than wavelength of blue light. The wavelength 450 nm to 495 nm. Let the thickness of oil is 400 nm.
By the constructive interference formula,
2nt = mλ
2 X 1.28 X 400 X 10^(-9) = 2λ
λ = 512 nm
This is the wavelength of green light.
