Read the sentence. telescopes or satellites _____ that neither mercury nor venus _____ a moon. which pair of verb forms correctl

vredina [299]

When there is or in-between two words, the tense is dependent upon the word that comes after or. In other words, the word that is closest to the verb will decide the form of the verb.

Since satellites is a plural form of a satellite, the verb that follows satellites should also be plural. The plural verb in the given options is prove.

As far as the second blank is concerned, you can see Venus is a proper noun; therefore, the verb that comes after Venus should be a singular verb, which in this case is has.

So the complete sentence would become the following:

Telescopes and satellites prove that neither Mercury nor Venus has a moon.

Correct pair: prove:has

In a parallel circuit, what’s happens to the current through each resistor when the voltage is doubled?

34kurt

Answer:

A

Explanation:

Voltage, V = Current, I x Resistance, R (V is directly proportional to I where R is constant of proportionality)

This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.

A standard baseball has a circumference of apoximately 23cm. If a baseball had the same mass per unit volume as a neutron or a p

BigorU [14]

Baseball, neutrons, and protons are all perfect spheres.

Circumference of the baseball, $L_{\text {ball }}=23 \mathrm{~cm}$ .

mass of the proton or neutron, $m_{\mathrm{p}}=10^{-27} \mathrm{~kg}$

diameter of the proton or neutron, $r_{0}=10^{-15} \mathrm{~m}$

Mass per unit volume is the definition of a material's density. The density equation is

$\rho=\frac{M}{V} .$

Here, M is the mass of the material, V is the volume, and $\rho$ is the density of the material.

We know that formula for the volume of a sphere having diameter d is $V=\frac{\pi d^{3}}{6}$.$

You may obtain this result by plugging this number into the proton/neutron density equation:

$\rho_{0}=\frac{m_{0}}{\left(\frac{\pi d_{0}^{3}}{6}\right)}$

By replacing the variables in the aforementioned equation with their values, you will obtain

$\begin{aligned}\rho_{\circ} &=\frac{10^{-27}}{\left(\frac{\pi\left(10^{-15}\right)^{3}}{6}\right)} \\&=1.91 \times 10^{18} \mathrm{kgm}^{-3}\end{aligned}$

The formula for calculating a circle's circumference with diameter d is $L=\pi d$.$

Using this, you get the diameter of the baseball:

$\begin{aligned}d_{\text {ball }} &=\frac{L_{\text {ball }}}{\pi} \\&=\frac{23}{\pi} \\&=7.32 \mathrm{~cm} \\&=0.0732 \mathrm{~m}\end{aligned}$

The volume of the baseball may be calculated using the formula for the volume of a sphere:

$\begin{aligned}V_{\text {ball }} &=\frac{\pi d_{\text {ball }}^{3}}{6} \\&=\frac{\pi \times(0.0732)^{3}}{6} \\&=2.054 \times 10^{-4} \mathrm{~m}^{3}\end{aligned}$

The mass of the baseball is determined by the concept of density if you suppose that its density is equal to that of a proton or neutron.

$m_{\text {ball }}=\rho_{\circ} \cdot V_{\text {ball }}$

Here, $\rho_{\circ}$ is the density of the proton/neutron.

By replacing the variables in the aforementioned equation with their values, you will obtain

$\begin{aligned}m_{\text {ball }} &=\left(1.91 \times 10^{18}\right) \cdot\left(2.054 \times 10^{-4}\right) \\&=3.92 \times 10^{14} \mathrm{~kg}\end{aligned}$

Therefore, if the density of the baseball was equal to that of the neutron/proton, then its mass would be $3.92 \times 10^{14} \mathrm{~kg}$.$
