A volume variance is the difference between overhead at maximum production volume and that at the budgeted production volume.

umka21 [38]

The statement is not correct. Therefore, the answer is letter B. False. The actual definition of a volume variance is that it is the difference of the quantity consumed and the amount budgeted to be sold, the difference will furthermore be multiplied to the standard unit per price.

Determine the electrical and gravitational forces that two protons in the nucleus of a helium atom exert on each other when sepa

jonny [76]

Answer:

Fe = 25.67 N

Fg = 2.0734 x 10^-35 N

Explanation:

r = 3 x 10^-15 m

G = 6.67 x 10^-11 Nm^2/kg^2

Mp = 1.6726231 x 10^-27 kg

Qp = 1.6021 x 10^-19 C

K = 9 x 10^9 Nm^2/C^2

The formula for the electrical force between the two protons is given by

$F = K \frac{Q_{p}\times Q_{p}}{r^{2}}$

$F = \frac{9\times 10^{9}\times 1.6021\times 10^{-19}\times 1.6021\times 10^{-19}}{3\times 10^{-15}\times 3\times 10^{-15}}$

Fe = 25.67 N

The formula for the gravitational force between the two protons is given by

$F = G \frac{M_{p}\times M_{p}}{r^{2}}$

$F = \frac{6.67\times 10^{-11}\times 1.6726231\times 10^{-27}\times 1.6726231\times 10^{-27}}{3\times 10^{-15}\times 3\times 10^{-15}}$

Fg = 2.0734 x 10^-35 N

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

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