Jill does twice as much work as Jack does and in half the time. Jill's power output is Group of answer choices one-fourth as muc
Musya8 [376]

Answer:

Second Choice.

Explanation:

Jack's Power = W/t

Jill's Power = 2W/(0.5)*t

2/0.5 = 4

Jill's Power = 4*W/t

Jill's Power is 4 times greater than Jack's

A long copper wire of radius 0.321 mm has a linear charge density of 0.100 μC/m. Find the electric field at a point 5.00 cm from
krek1111 [17]

Answer:

E=35921.96N/C

Explanation:

From the question we are told that:

Radius r=0.321mm

Charge Density \mu=0.100

Distance d= 5.00 cm

Generally the equation for electric field is mathematically given by

E=\frac{mu}{2\pi E_0r}

E=\frac{0.100*10^{-6}}{2*3.142*8.86*10^{-12}*5*10^{-2}}

E=35921.96N/C

How does changing the potential difference in a circuit affect the current and the resistance?
Effectus [21]

Answer:

The current will be increased and also for the resistance.

Explanation:

The analysis of a direct current circuit can give us the explanation we need. Using the ohm law, which tells us that the voltage is equal to the product of the current by the resistance we have:

V=I*R\\where\\V= voltage [V]\\I= amperes [amp]\\R=resistance [ohm]\\

The voltage is equal to the potential difference therefore we will have these expressions:

I=\frac{V}{R} \\R= \frac{V}{I}

If we increase the potential differential or circuit voltage, the current will also increase and so does the resistance by increasing the voltage. If we put numerical values in the equation given before, we can confirm this fact.

What is the frequency of X-rays of 10 nm wavelength? 6 x 1016 Hz 3 x 1016 Hz 3.00 Hz 6 x 108 Hz
Evgesh-ka [11]

The frequency of any wave is  (wave speed) / (wavelength) .

The speed of light is  3 x 10⁸ m/s.
If the wavelength is 10 nm (10⁻⁸ m) , then the frequency is

                         (3 x 10⁸) / (10⁻⁸)  =  <em>3 x 10¹⁶ Hz</em>

That's 30 million gigahertz !
