Question

ХЕЛП Літак знаходиться на відстані 45 км від радіолокатора. Визначте час, за який сигнал радара доходить до літака. ​

Answer 1

Ответ:

0,00015 сек

Объяснение:

Скорость радиоволны 300 тыс.км/сек

1 км радиоволна пройдет за 1/300 000 сек = 0,0000033 сек

45 км = 0,00015 сек = 15 *10^5

Answer 2

Calculating Time for Radar Signal to Reach the Plane

To calculate the time it takes for the radar signal to reach the plane, we can use the formula: time = distance / speed.

Given: - Distance from the radar to the plane (d) = 45 km - Speed of the radar signal (v) = 3 × 10^8 m/s (speed of light)

Using the formula, we can calculate the time it takes for the radar signal to reach the plane:

time = distance / speed time = 45 km / (3 × 10^8 m/s)

Converting the distance to meters: 45 km = 45 × 1000 m = 45000 m

Now, we can calculate the time: time = 45000 m / (3 × 10^8 m/s) time = 0.00015 seconds

So, the time it takes for the radar signal to reach the plane is approximately 0.00015 seconds.

This calculation is based on the speed of light and the given distance from the radar to the plane.
