A generator's maximum output is 220 V. What is the rms potential difference?

1 answer:

3 0

The rms potential difference is defined as the peak value of the potential difference divided by the square root of 2:
$V_{rms} = \frac{V_0}{ \sqrt{2} }$
where
$V_0$ is the peak value of the voltage (the maximum voltage).

The generator in our problem has a maximum voltage of $V_0=220 V$ , so its rms potential difference is
$V_{rms}= \frac{V_0}{ \sqrt{2} }=155.6 V$

Why is it important not to present a biased argument as a public speaker?

UNO [17]

Answer:

Explanation:

a) because it's immoral as you're trying to convince people of your views when you should be giving both sides of the story so people are able to come up with their own opinions on what you're talking about

the acceleration of a rocket traveling upward is given by a=(6+.02s)m/s^s, where s is in meters. Determine the rocket's velocity

NikAS [45]

Answer:

a) velocity v = 322.5m/s

b) time t = 19.27s

Explanation:

Note that;

ads = vdv

where

a is acceleration

s is distance

v is velocity

Given;

a = 6 + 0.02s

so,

$\int\limits^s_0 {a} \, ds = \int\limits^v_0 {v} \, dv\\ \int\limits^s_0 {6+0.02s} \, ds = \int\limits^v_0 {v} \, dv\\ 6s + \frac{0.02s^{2} }{2} = \frac{1}{2} v^{2} \\v = \sqrt{12s + 0.02s^{2} } .....................1 \\\\\\$

Remember that

$v = \frac{ds}{dt} \\\frac{ds}{v} = dt\\\int\limits^s_0 {\frac{ds}{\sqrt{12s+0.02s^{2} } } } \, ds = \int\limits^t_0 {} \, dt \\t= (5\sqrt{2} ) ln \frac{| [s + 300 + \sqrt{(s^{2} + 600s)} ] |}{300} .......2$
