Answer:
.
Explanation:
Intensity of the electromagnetic radiation is given by
where is the distance from the EM source (the center of the sun, in our case), and
is the power output of the sun and it has the value
Since the radius of the sun in meters is , the intensity
of the electromagnetic radiation at the surface of the sun is
The intensity of the electromagnetic radiation at the surface of the sun is .
Answer:
The current in the heater is 12.5 A
Explanation:
It is given that,
Power of electric heater, P₁ = 1400 W
Power of toaster, P₂ = 1150 W
Power of electric grill, P₃ = 1560 W
All three appliances are connected in parallel across a 112 V emf source. We need to find the current in the heater. We know that in parallel combination of resistors the current flowing in every branch of resistor divides while the voltage is same.
Electric power,
So, the current in the heater is 12.5 A. Hence, this is the required solution.
