Two capacitors with capacitances of 1.5

English
1 answer:
kolbaska11 [484]3 years ago
8 0

Answer:

E = 1.9 * 10^{-3}J

Explanation:

The complete question is summarized as thus:

Given

C_1 =1.5\mu F

C_2 =0.25\mu F

V = 50V --- voltage

Connect type: Parallel

Required

The potential energy stored in the 1.5\mu F capacitor

The energy stored is calculated as:

E = \frac{1}{2}CV^2

Where:

C = C_1 =1.5\mu F --- the capacitor

V = 50V --- the voltage across the capacitor

So, we have:

E = \frac{1}{2} * 1.5\mu F * (50V)^2

Convert to Farad

E = \frac{1}{2} * 1.5 * 10^{-6} F * (50V)^2

E = \frac{1}{2} * 1.5 * 10^{-6} F * 2500V^2

E = 0.001875J

Rewrite as:

E = 1.875 * 10^{-3}J

Approximate

E = 1.9 * 10^{-3}J

When giving a public speech, a neat, appropriate appearance _____.
Cloud [144]
Out of these choices, the best one to pick would be B. 

Being neat will only cause your audience to respect you and take you seriously, which eliminates choices A and C.

And I can almost guarantee you that if you did a public speech in your pajamas, it would be relevant and it would cause your audience not to respect you while you're speaking, which eliminates choice D.
