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.
When you and a friend move a couch to another room you exert a force of 75 N over 5m how much work will you do
1 answer:
The work done is 375 J
Explanation:
The work done by a force in moving an object is given by
where
F is the magnitude of the force
d is the displacement
is the angle between the direction of the force and the displacement
In this problem,
F = 75 N is the force applied to the couch
d = 5 m is the displacement
Assuming the force applied to the couch is parallel to the motion,
And so, the work done is
