A mass of 0.3 kg is suspended from a spring of stiffness 0.4 N/mm. The damping is 3.286335345 kg/s. What is the undamped natural

mina [271]

Answer:

f=5.81 Hz

Explanation:

Given that

m= 0.3 kg

K= 0.4 N/mm

K= 400 N/m

C= 3.28

We know that undamped natural frequency given as

$\omega= \sqrt{\dfrac{K}{m}}$

Now by putting the values

$\omega= \sqrt{\dfrac{K}{m}}$

$\omega= \sqrt{\dfrac{400}{0.3}}$

ω = 36.51 rad/s

We know that

ω = 2 π f

36.51 = 2 x π x f

f=5.81 Hz

So the undamped natural frequency is 5.81 Hz.

If 1 uF capacitor is fully charged with 120 V across it, how much energy is stored in it? (a) 7.2 kJ (b) 7.2 mJ (c) 0.12 mJ (d)

jeyben [28]

Answer:

(b) 7.2 mJ

Explanation:

ENERGY STORED IN CAPACITOR: the energy is stored in capacitor in electric field

which can be calculated by expressions

E= $\frac{1}{2}$ c $v{^2}$

= $\frac{1}{2}$ $10^{-6}$ $120^{2}$

=7200× $10^{-6}$ J

= 7.2× $10^{-3}$ J

=7.2 mJ
