Answer:
.25 Hz
Explanation:
Period = 4 sec
freq = 1/p = 1/4 hz = .25 Hz
The correct answer to this question is "2.1 kgm/s." The impulse results if the force acting on an object that is described by the force-time graph shown is that 2.1 kgm/s. Based on the graph, it shows like a plateau with the flat at the force of 2.1 N.
Answer:
530.5 Hz
Explanation:
Given :
C=0.75 micro
L=120 mH
Reactance capacitor can be determined by
=
where c =capacitor
= 
Reactance inductor can be determined by

As they are in series so ,

On solving these value we get

As we know that
f =
=
530.5 Hz
