The intensity of light from the Sun is 1.3 kW/m² at the distance of the Earth.The Earth's radius is 6.4 × 10⁶ m.If all the sunlight that hits the Earth were absorbed,what would be the magnitude of the resulting force on the Earth? A)0.0087 N B)1.8 × 10⁸ N C)5.6 × 10⁸ N D)87 N

Question

Quizplus · Accepted Answer

The force can be calculated using the formula F = (Power/Speed of light) * Area. The power is the intensity times the area of the Earth's cross-section (πR²), and the speed of light is approximately 3 × 10^8 m/s.

The Intensity of Light from the Sun Is 1
