Answer:
<h2>34.67 W</h2>Explanation:
Power is the rate at which work is done and can be found by using the formula
p is the power in Watts (W)
w is the workdone in joules
t is time in s
but workdone = force × distance
From the question
force = 780 N
distance = 2 m
workdone = 780 × 2 = 1560 N
Since we now have the value of workdone we can find the power
We have
We have the final answer as
<h3>34.67 W</h3>Hope this helps you
Given:
The initial volume of the gas, V₁=3200 ml=3.2×10⁻³ m³
The initial pressure of the gas, P₁=122 kPa
The initial temperature of the gas, T₁=27 °C=300 K
The final temperature, T₂=65 °C=338 K
The final pressure, P₂=112 kPa
To find:
The final volume of xenon gas.
Explanation:
From the combined gas law,
Where V₂ is the volume after it is heated.
On rearranging the above equation,
On substituting the known values,
Final answer:
The volume of the balloon when it is heated is 3.61 m³
