The quantity of charge passing through a surface of area 1.82 cm2 varies with time as q = q1 t 3 + q2 t + q3 , where q1 = 5.2 C/
s 3 , q2 = 2.5 C/s, q3 = 6.5 C, and t is in seconds. What is the instantaneous current through the surface at t = 1.1 s? Answer in units of A.
1 answer:
Answer:
Current through the surface at t = 1.1 s is 21.37 A.
Explanation:
The charge is passing through a surface of area varies with time as :

Here,

t is in seconds

The rate of change of electric charge is called electric current. It is given by :

At t = 1.1 s, Current,

So, the instantaneous current through the surface at t = 1.1 s is 21.37 A.

Net Force = (mass) x (acceleration) (Newton #2)
Net Force = (50 kg) x (6 m/s² down)
Net Force = (50 * 6) (kg-m/s² down)
<em>Net Force = 300 Newtons down</em>
