Question

Вычислите линейную скорость вращения на экваторе земли, если радиус земли 5400 км Физика 10 класс Срочно пожалуйста.

Answer 1

Ответ:

Объяснение:

R = 5400 км = 5,4⋅10⁶ м

T ≈ 24 ч = 8,64⋅10⁴ c

V - ?

==========

V = 2πR / T = 2·3,14·5,4⋅10⁶ / 8,64⋅10⁴ = 392,5 м/с

Answer 2

Calculation of Linear Speed of Earth's Rotation at the Equator

To calculate the linear speed of Earth's rotation at the equator, we need to use the formula:

Linear Speed = 2 * π * Radius / Time

Where: - π is a mathematical constant approximately equal to 3.14159 - Radius is the radius of the Earth at the equator, which is given as 5400 km - Time is the time taken for one complete rotation of the Earth, which is approximately 24 hours or 86400 seconds

Let's substitute the values into the formula and calculate the linear speed:

Linear Speed = 2 * 3.14159 * 5400 km / 86400 seconds

Calculating this expression gives us the linear speed of Earth's rotation at the equator.

Please note that the radius of the Earth should be converted to meters before performing the calculation, as the formula requires consistent units.
