An electron is taken into consideration to be the many basic unit of charge. The amount of charge lugged by an electron is the minimum quantized charge. The electrons bring the negative charge whereas the protons carry the very same amount of the positive charge.

You are watching: How many electrons are necessary to produce 1.0 c of negative charge? (e = 1.60 × 10-19 c)

The charge on an electron is

14 mL

Explanation:

Ideal gas law:

PV = nRT

If n is constant, then:

PV / T = PV / T

(0.819 atm) (17.9 mL) / (273 + 28) K = (0.99 atm) V / (273 + 13) K

V = 14 mL

A 5 kg wooden block sitkid a level straight-away12 meters fromthe bottom of an infinitely long ramp, which has an angle of 20 deg
saveliy_v <14>

slrfc.org:

(a) 19.71801m/s Velocity just before going up the ramp.

(b) 74.56338m.

Explanation:

We will certainly solve it in 2 parts, initially we will certainly calculate time that 5kg wood block would certainly take to simply reach ramp and with this time we will certainly calculate final velocity that the wooden block would certainly have actually in this time.

Second, we will certainly calculate the component of velocity vector along inclined aircraft and the moment that it would take for velocity to be 0 meters/s then through this time we will calculate the distance that inclined airplane would travel along inclined plane.

Following formulas will certainly be offered.

*

*

*

*

(a) Calculating velocity appropriate before going up the ramp.

Wooden block is going on a straightaway and has actually net for on it.

*
=
*

and also this force produces acceleration of

*

With this acceleration, wooden block would certainly reach at the foot of ramp in.

*

*

and also last velocity will certainly be

*

this velocity of wood box simply before going up the ramp.

(b) How far up the ramp will the wood block go before protecting against.

Ramp is at 20° relative to horizontal therefore velocity alengthy the ramp that the wooden block would certainly have actually will certainly be.

*

and deceleration alengthy the ramp is

*

Where

*
force of friction along the inclined plane.

*

*

is a component of g alengthy normal of the inclined plane.

*

*

*

And with this deceleration time essential to obtain wooded block to sheight is.

*

*

and also in that time wood block would certainly travel

*

This is how up wooden box will go prior to coming to sheight.


The correct slrfc.org to the question is by raising their masses, or by decreasing the separation distance between them.

EXPLANATION:

Let us think about 2 bodies having actually masses M and also M" respectively . The 2 bodies are separated from their centre of masses by a distance of R.

As per Newton"s legislation of gravitation, the two bodies will certainly exert gravitational pressure on one an additional. The gravitational pressure created in between them is calculated as -

Gravitational force

*

Here, G is the gravitational pressure constant.

From above, we see that the gravitational force is directly proportional to the product of masses of 2 bodies and also inversely proportional to the square of separation distance in between them.

Hence, the gravitational pressure between two objects have the right to be boosted by boosting their masses, or by decreasing the distance between them.
