Aluminum foil reflects more light
Answer:
Explanation:
Average power per unit area =
I avg = c B₀² / 2μ₀
= 3 X 10⁸ X (3.2 X 10⁻⁷)² / 2 X 4π × 10⁻⁷
= 1.22 X 10
12 . 2 W / m²
Answer:
Distance traveled by car in 25 L IS 396.15 km
Explanation:
We have given average millage of car = 60 km /gal
Means car travel 60 km in 1 gallon
The amount of gasoline = 25 L
We know that 1 L = 0.2641 gallon
So 
As the car travels 60 km in 1 gallon
So traveled distance by car in 6.6025 gallon of gasoline = 60×6.6025 = 396.15 km
Answer:
V = 0.0392 volt
Explanation:
given that the
Current I = 0.7 mA
Resistance R = 56 Ohms
According to Ohm's law,
V = IR
Where V is the Voltage in the circuit.
Substitute I and R into the formula
V = 0.7 ×10^-3 × 56
V = 0.0392 volt
The ammeter can be use to read current in a circuit when it is connected to the device in which the resistors are connected in series.
While for the Voltmeter, the resistors are connected in parallel.
