Answer:
Acceleration, a = 6 m/s²
Explanation:
It is given that,
The police department is excited to have some new motorcycle units. one officer said that these motorcycles can go from 0 miles per hour to 80 miles per hour in just 6 seconds.
Initial speed of motorcycle, u = 0
Final speed, v = 80 miles/h = 35.8 m/s
Time taken, t = 6 s
The officer is describing the motorcycle's acceleration and it can be calculated by :
a = 5.966 m/s²
or a = 6 m/s²
Hence, the acceleration of the motorcycle is 6 m/s².

Answer : The work done by the system is, 2.2722 J
Explanation :
The expression used for work done in reversible isothermal expansion will be,
where,
w = work done = ?
n = number of moles of gas = 0.00100 mole
R = gas constant = 8.314 J/mole K
T = temperature of gas =
= initial volume of gas = 25 mL
= final volume of gas = 75 mL
Now put all the given values in the above formula, we get:
Therefore, the work done by the system is, 2.2722 J
