Автор ответа: prirodaone

Ответ:

A = 1000 кДж

Объяснение:

Дано:

s = 1 км = 1000 м (перемещение)

F = 1 кH = 1000 H ( сила, создаваемая двигателем)

A - ? ( работа выполняемая двигателем)

Находим A с помощью формулы:

A = F × s (формула для определения работы )

A = 1000 H × 1000 м

A = 1000000 Дж = 1000 кДж

A = 1000 кДж
