Answer: 60 degrees Celsius
Explanation:
Answer:
0.99 m³
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law </em>to calculate the volume
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₁
p₁V₁ = p₂V₂T₁/T₂ Divide each side by p₁
V₁ = V₂ × p₂/p₁ × T₁/T₂
<em>Data:
</em>
p₁ = 201 kPa; V₁ = ?; T₁ = 27 °C = 300.15 K
p₂ = 2.5 kPa; V₂ = 59.3 m³; T₂ = -14 °C = 223.15 K
<em>Calculation:
</em>
V₁ = 59.3 × 2.5/201 × 300.15/223.15
V₁ = 20 × 0.0124 × 1.345
V₁ = 0.99 m³
Answer:
The box will move towards me by the additional force of 60N.
Explanation:
I am pulling the box with a force of 30N and my friend is pushing the box in the same direction with a force of 30N.
Here two forces are exhibited in the same direction that is towards myself as a result the box will move towards me by an additional force of 30N+30N=60N.
