An AC voltage source has an output of ∆V = 160.0 sin(495t) Volts. Calculate the RMS voltage. Tries 0/20 What is the frequency of

kupik [55]

Answer:

RMS voltage is 113.1370 V

frequency is 780.685 Hz

voltage is −158.66942 V

maximum current is 2.9739 A

Explanation:

Given data

∆V = 160.0 sin(495t) Volts

so Vmax = 160

and angular frequency = 495

time t = 1/106 s

resistor R = 53.8 Ω

to find out

RMS voltage and frequency of the source and voltage and maximum current

solution

we know voltage equation = Vmax sin ωt

here Vmax is 160 as given equation in question

so RMS will be Vmax / √2

RMS voltage = 160/ √2

RMS voltage is 113.1370 V

and frequency = angular frequency / 2π

so frequency = 497 / 2π

frequency is 780.685 Hz

voltage at time (1/106) s

V(t) = 160.0 sin(495/ 108)

voltage = −158.66942 V

so current from ohm law at resistor R 53.8 Ω

maximum current = voltage max / resistor

maximum current = 160 / 53.8

maximum current = 2.9739 A

How long must a simple pendulum be if it is to make exactly one swing per second? (That is, one complete vibration takes exactly

umka2103 [35]

Oscillation is a type of periodic motion which repeats itself to and from about a point which is called mean position. The period of a Pendulum can be described as a ratio between the length and gravity as,

$T = 2\pi \sqrt{\frac{L}{g}}$

Here,

L = length

g = Gravity

If we rearrange to find the length we have that,

$L = \frac{T^2g}{4\pi^2}$

Our period is 2s and the gravity is 9.8m/s^2, then,

$L = \frac{(2)^2(9.8)}{4\pi^2}$

$L = 0.9929m$

The simple required length of the pendulum must be 0.9929m

Find the statement about Fusion that is false.

stiks02 [169]

Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.

Fusion could be the world's answer to clean unlimited amounts of energy.

Fusion is extremely difficult to contain and maintain here on earth.

Explanation:

Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.

The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.

As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
it is known that nuclear fusion produces far more energy than fission reaction.
It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.
