Answer:
60.4 J
Explanation:
The work done by the gas is given by:
where
p is the gas pressure
is the final volume of the gas
is the initial volume
We must convert all the quantities into SI units:
So the work done is
Answer: 981 Pa
Explanation:
1) Data:
m = 60 kg
S = 6000 cm²
P = ?
2) Formulas
i) F = peso = mg
ii) P = F / S
3) Solution
i) F = 60kg × 9.81 m/s² = 588.6 N
ii) P = F / S
First, convert 6000 cm² to m²: 6000 cm² × 1m² / (100cm)² = 0.6 m²
Now, plug in the values and do the operations: P = 588.6N / 0.6m² = 981 Pa
Answer:
Explanation:
The force is defined as the negative of the derivative of the potential energy:
If we use the potential energy function given in this problem:
and we calculate the force, we get:
So, the force is
Answer:
