Question

P=1000H h=20м работа (А) -?

Answer 1

A=Ph
A=1000H*20м=20 000 Дж = 20 кДж

Answer 2

A=FS=Ph
A=1 000*20=20 000 (Дж)

Answer 3

To calculate the work (W) in Joules (J), we can use the formula:

W = P × h

where: P = pressure (in Pascal, Pa) h = height (in meters, m)

Given: P = 1000 H (I assume "H" means Hectopascal, hPa, which is equivalent to 100 Pascal) h = 20 meters

Let's plug the values into the formula:

W = 1000 hPa × 20 m

Now, to get the work in Joules, we need to convert the pressure from hectopascal (hPa) to Pascal (Pa):

1 hPa = 100 Pa

W = (1000 hPa × 100 Pa/hPa) × 20 m

W = 100,000 Pa × 20 m

W = 2,000,000 Joules (J)

So, the work done in this scenario is 2,000,000 Joules (or 2 Megajoules).
