Answer:
The time constant is 1.049.
Explanation:
Given that,
Charge
We need to calculate the time constant
Using expression for charging in a RC circuit
Where, = time constant
Put the value into the formula
Hence, The time constant is 1.049.

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that the friction force on two boxes is given as
Now we know by Newton's II law
so we have
Part b)
For block B we know that net force on it will push it forward with same acceleration so we have
Part c)
If Alex push from other side then also the acceleration will be same
So for box B we can say that Net force is given as
