<span>Free electrons may be transferred between bodies by "Contact Action"

When positively charged body comes close to a negatively charged body, then electron flows from positively to negatively charged body

In short, Your Answer would be Option B

Hope this helps!</span>

Answer:

B) contact action

Explanation:

When two conductors are connected with each other then in that case the free charge of one conductor may be transferred to other if the potential of one conductor is not same as the potential of other conductor.

As we know that positive charge always move from higher potential to lower potential.

So here when two bodies are connected together then in that case electron from one body is transferred to other body if the the potential of two bodies are not same.

So here correct answer will be

B) contact action

Light travels 186 000 miles per second.how many miles dose light travel in one year
Troyanec [42]

       (186,000 mi/sec) x (3,600 sec/hr) x (24 hr/da) x (365 da/yr)

  =   (186,000 x 3,600 x 24 x 365)  mi/yr

  =      5,865,696,000,000  miles per year  (rounded to the nearest million miles)

I need help with this

We have here what is known as parallel combination of resistors.

Using the relation:

\frac{1}{ r_{eff} } = \frac{1}{ r_{1} } + \frac{1}{ r_{2} } + \frac{1}{ r_{3} }.. . + \frac{1}{ r_{n} } \\
And then we can turn take the inverse to get the effective resistance.

Where r is the magnitude of the resistance offered by each resistor.

In this case we have,
(every term has an mho in the end)
\frac{1}{10000} + \frac{1}{2000} + \frac{1}{1000} \\ \\ = \frac{1}{1000} ( \frac{1}{10} + \frac{1}{2} + \frac{1}{1} ) \\ \\ = \frac{1}{1000} ( \frac{31}{20}) \\ \\ = \frac{31}{20000}

To ger effective resistance take the inverse:
we get,
\frac{20000}{31} \: ohm \\ = 645 .16 \: ohm

The potential difference is of 9V.

So the current flowing using ohm's law,

V = IR

will be, 0.0139 Amperes.

Do all metals expand the same amount when heated??
ahrayia [7]

Answer:

No

Explanation:

The rate at which solids expand when heated depends on the substance. Metals tend to have higher rates of expansion (per degree change in temperature) than non-metal solids, but there is variation even among metals. A table of expansion coefficients can be found here or here.
