Answer:
Explanation:
From the question we are told that
Temp of first bolts
Temp of 2nd bolt
Generally the equation showing the relationship between heat & temperature is given by
Generally heat released by the iron bolt = heat gained by the iron bolt
Generally solving mathematically
Therefore is the final temperature inside the container
What the question for this assessment
Momentum (p) = mass × velocity
P= 200,000×4.5
P= 900,000 .... answer !!
Answer:
The entropy of a gas increases when it expands into a vacuum because the number of possible states increases .
Explanation:
When a gas expand in a vacuum, the molecules of the gases vibrates very fast and starting moving with higher velocity in random directions which means the level of disorder in the gases increases.
Now the possible state of the gas molecule increases such as the particle can be located at different position due to increased randomness.
<u>Entropy is the measure of this randomness and thus with this increased randomness entropy also increases.</u>
The formula for velocity vf = vi + at
First list your given information
2m/s Is your initial velocity (vi)
6m/s is you final velocity (vf)
2 seconds is your time (t)
Since you want the a for acceleration get a by itself
a = (vf-vi)/t
So a= (6-2)/2
a= 4/2
a=2
Now units
the units for acceleration are m/s
2m/s
