Question

W-72 кДж U-127 Дж q-?

Answer 1

w = U q

q = w/U = 72 000 Дж / 127 В = 567 Кл

Answer 2

To find the value of q, we can use the formula:

q = W - U

where W is the work done on the system and U is the change in internal energy.

Given: W = 72 kJ (kilojoules) U = 127 J (joules)

We need to convert the units so that they are in the same base unit. Let's convert 72 kJ to joules:

1 kilojoule (kJ) = 1000 joules (J)

Therefore, 72 kJ = 72,000 J

Now we can substitute the values into the formula:

q = 72,000 J - 127 J q = 71,873 J

Therefore, the value of q is approximately 71,873 joules.
