U=72км/сағd=40смT=?​

Answer 1

Не обращайте внимания на вычеркивания
Ответ:Т=0,02 с

Answer 2

It seems like you've provided some symbols and values without context. However, based on the information you've given, I can try to interpret it and find a solution:

U = 72 km/s (velocity) d = 40 cm (distance) T = ? (time)

To find the time (T), you can use the formula:

Time (T) = Distance (d) / Velocity (U)

First, we need to convert the velocity from km/s to cm/s to match the units of distance:

72 km/s * 100,000 cm/km = 7,200,000 cm/s

Now, we can calculate the time:

T = 40 cm / 7,200,000 cm/s ≈ 5.56e-6 seconds

The time (T) is approximately 5.56 microseconds.
