Question

Concepts
and C = 0.500 uF. (a) Find the current at t = 0:3 s.
(b) Find the rate of change of current at t = 0:3 s.
(c) Find approximately the current at t = 0:31 s.

27. A rod of length L is placed along the X-axis between
x = 0 and x = L. The linear density (mass length) p of
the rod varies with the distance x from the origin as
p= a + bx. (a) Find the SI units of a and b. (b) Find the
mass of the rod in terms of a, b and L.
28. The momentum p of a particle changes with time t
according to the relation = (10 N) + (2 N/s)t. If the
momentum is zero at t = 0, what will the momentum be
at t = 10 s?
