A cubical Gaussian surface surrounds two positive charges, each has a charge q 1 1 = + 3.90 × 10 − 12 3.90×10−12 C, and three ne
Masteriza [31]

Answer:

The electric flux is zero because charge is zero.

Explanation:

Given that,

Positive charge q_{1}=3.90\times10^{-12}\ C

Negative charge q_{2}=-2.60\times10^{-12}\ C

We need to calculate the total charged

Using formula of charge

Q_{enc}=2q_{1}+3q_{2}

Put the value into the formula

Q_{enc}=2\times3.90\times10^{-12}+3\times(-2.60\times10^{-12})

Q_{enc}=0

We need to calculate the electric flux

Using formula of electric flux

\phi=\dfrac{Q_{enc}}{\epsilon_{0}}

Put the value into the formula

\phi=\dfrac{0}{8.85\times10^{-12}}

Hence, The electric flux is zero because charge is zero.

If one oscillation has 5.8 times the energy of a second one of equal frequency and mass, what is the ratio of their amplitudes?
vovikov84 [41]

If one oscillation has 5.8 times the energy of the second one of equal frequency and mass, 2.4:1 is the ratio of their amplitudes.

Oscillation is defined as the process of repeating fluctuations of a quantity or measure around its time equilibrium value. Oscillation can also be defined as the periodic fluctuation of matter between two values ​​or about their average.

The definition of happiness is someone or something that makes you feel great joy or pleasure. An example of good luck is someone who wins the lottery. An example of happiness is a laughing baby. Besides making you feel better, positive emotions are good for your brain and body. It lowers stress hormones, relieves anxiety and depression, and strengthens the immune system. Feeling positive emotions every day has a huge impact on our well-being and health.

A student hooks up a voltmeter and an ammeter in a circuit to find the resistance of a light bulb. The ammeter read 3 amps and t
yuradex [85]

Answer:

2\Omega

Explanation:

(Assuming the cell in the circuit has 0 internal resistance)

Ohm's Law is given as:

V=IR

Voltage is Current multiplied by Resistance.

We can rearrange this formula to give us:

R=\frac{V}{I}

Now we can plug in our values

R=\frac{6}{3}=2\Omega
