Question

СРОЧНО НАРОД НЕ ПРОХОДИТЕ МИМО ФИЗИКА ДАМ 100Б Дано: V- 70 км/ч V-18 м/с _________ Какая скорость больше? ___________________________ Прошу ответить развернуто и с объяснением

Answer 1

Ответ:

70км/ч

Объяснение:

Надо 70*1000:3600≈19,4м/с

Следовательно 19,4 м/с > 18 м/с

Answer 2

Which speed is greater: V = 70 km/h or V = 18 m/s?

To determine which speed is greater, we need to convert both speeds to the same unit of measurement. Let's convert V = 70 km/h to m/s.

1 km = 1000 m 1 h = 3600 s

To convert km/h to m/s, we can use the following conversion factor:

1 km/h = (1000 m / 1 km) / (3600 s / 1 h) = 1000 / 3600 m/s ≈ 0.2778 m/s

Now, let's convert V = 70 km/h to m/s:

V = 70 km/h * 0.2778 m/s = 19.4444 m/s

So, V = 70 km/h is approximately equal to V = 19.4444 m/s.

Now, let's compare V = 19.4444 m/s with V = 18 m/s.

Since V = 19.4444 m/s is greater than V = 18 m/s, we can conclude that the speed V = 70 km/h is greater than the speed V = 18 m/s.

Please note that the conversion factors used in this explanation are standard and widely accepted. However, it's always a good practice to double-check the conversion factors and calculations to ensure accuracy.
