Question

The Earth is approximately spherical, with a diameter of 1.27×10^7 meters. How long does it take for the Earth to complete one revolution, given that the time taken is 24.0 hours?

Answer 1

The Earth takes approximately 24.0 hours to complete one revolution.

Step-by-step explanation:

The Earth takes approximately 24.0 hours to complete one revolution.

To calculate the time taken for one revolution of the Earth, we can use the formula:

Time (T) = Circumference/Speed

The circumference of a sphere can be calculated using the formula:

Circumference = 2πr

where r is the radius of the Earth.

Substituting the values given:

T = 2π(1.27×10^7)/24.0

Simplifying the equation gives:

T ≈ 2.11×10^6 seconds
