Задание 4.

Дано

m = 200т = 200 * 10³кг

P = 10МВт = 10*10⁶Вт

g = 10м/с²

Найти:

η - ?

η = Ап / Аз

Ап = P * t

Аз =  Fт * S = mgS

η = P*t / mgS = 10*10⁶ * t / 200*10³*10*S = 5t/S

t -не известно.

S - расстояние не известно.

ответ: η = 5t/S

Задание 1.

Дано:

m = 1 кг

h₀ = 50м

h1 = 20 м

g = 10 м/с²

Найти:

А- ?

A=Fт * S = mg* Δh = 1 * 10 * (50 - 20) = 300 Дж

ответ: 300 Дж

Задание 2

Дано:

k = 10000 Н/м

Δl =  8 см = 8 * 10⁻²м

Найти:

Ep - ?

Ep = k * Δl² / 2 = 10000 * 8 * 10⁻² / 2 = 400 Дж

ответ: 400 Дж.

Задание 3

Дано:

Δl₁ = 5 мм = 5 * 10⁻³ м

A₁= 3 кДж = 3 * 10³ Дж

Δl₂ = 1,2 см = 1,2 * 10⁻² м

Найти:

А₂-?

А = Ep = k *Δl² / 2

k =  2Ep  / Δl²  

A₂ =  2Ep₁  / Δl²₁ * Δl²₂ / 2 = Ep₁*Δl²₂ / Δl²₁ =  3 * 10³ * (1,2 * 10⁻²)² / (5 * 10⁻³)² = = 17280 Дж

ответ 17 280 Дж
