Question

с земли на луну был послан сигнал.спустя 2,6с отраженный от лунной поверхности сигнал приняли на земле.расчитайте расстояние от земли до луны,если скрость сигнала равна 300000 км/ч.

Answer 1

R -расстояние от земли до поверхности луны

2R =vt

R=vt/2=300000*2.6/2=390000 км

Answer 2

Calculation of Distance from Earth to the Moon

To calculate the distance from Earth to the Moon, we can use the information provided: the time it took for a signal to travel from Earth to the Moon and back.

Given: - Time taken for the signal to travel from Earth to the Moon and back = 2.6 seconds - Speed of the signal = 300,000 km/h

To calculate the distance, we can use the formula:

Distance = (Speed of the signal) * (Time taken for the signal to travel) / 2

Substituting the values:

Distance = (300,000 km/h) * (2.6 seconds) / 2

Calculating the distance:

Distance = 390,000 kilometers

Therefore, the distance from Earth to the Moon is approximately 390,000 kilometers.
