The number of particles in a gas system inversely affects _ and directly affects _.

1 answer:

5 0

The answer is A.
When a substance is a gas, it fills its container no matter how many particles it's made of, however the number of particles present will directly affect the pressure and temperature of the system.

How long could you survive without electricity? What parts of your life would be affected by loss of electricity?

Law Incorporation [45]

Answer:

Depends on the person, if you are hooked to your phone which most people are these days, you might go a little crazy. But think cavemen or anybody long ago, they survived without electricity. People in Africa bathe in the lake or any water nearby, they also walk for miles just to get drinking water. So yes, if you really tried you could go without electricity for possibly your whole life. It sucks if you have homework though because you don't have Brainly :)

At what position in its elliptical orbit is the speed of a planet a maximum? when it is closest to the sun when it is farthest f

Phantasy [73]

Answer:

1.when it is closest to the sun

2.when it is midway between its farthest

Explanation:

According to the law of Kepler's

T ² ∝ r³

T=Time period

r=semi major axis

We also know that time period T given as

$T=\dfrac{2\pi r}{v}$

v=Speed

$v=\dfrac{2\pi r}{T}$

$v\alpha \dfrac{r}{T}$

$v^2\alpha \dfrac{r^2}{T^2}$

$v^2\alpha \dfrac{r^2}{r^3}$

$v^2\alpha \dfrac{1}{r}$

$v\alpha \dfrac{1}{\sqrt{r}}$

So we can say that ,when r is more then the speed will be minimum and when r is low then speed will be maximum.

Inside a television picture tube there is a build-up of electrons (charge of 1. 602 × 10–19 C) with an average spacing of 38. 0

Olin [163]

The magnitude of the electric field inside the picture tube is 998.476 kN/C.

<h3>What is an electric field?</h3>

It is an area in the space where a charged particle experiences a force. It can be calculated by the formula,

$E =\dfrac {kQ}{r^2 }$

Where,

$E$ = electric field produced

$Q$ = charge = $1.602 \times 10^{-19}\rm \ C$

$r$ = distance = $38 \times 10^{-9}\rm \ m$

$k$ = Coulomb's constant = $9 \times 10^9 \rm \ N. m2 / C2$

Put the values in the formula,

$E = \dfrac {9 \times 10^9\times 1.602 \times 10^{-19}}{(38 \times 10^{-9})^2}\\\\E = 998.476 \rm \ kN/C$

Therefore, the magnitude of the electric field inside the picture tube is 998.476 kN/C.

Suppose you have avogadro\'s number of mini marshmallows and use them to cover the state of california which has a land area of

Marta_Voda [28]

Avogadro's number is equal to 6.02 E 23

Thie means we have 6.02 E 23 marshmallows.

Assuming each marshmallow to be a small cylinder we can calculate the area of its base

Area circumference = pi*r² = pi * (0.635/2)² = 0.317 cm²

So, 6.02 E 23 marshmallows * 0.317 cm² cover a total area of

Area covered = 1.908 E 23 cm² = 1.908 E 13 km²

<span>The land area of california is 1.560 E 5 mi</span>² = 4.04 E 5 km²

If we divide the Areas >>>>

1.908 E 13 km² / 4.04 E 5 km² = 47. 227 E 6 (This is the number of times the area of California could be filled with those marshmallows)

Now for the height, we multiply this number times the height of each marshmallow

47. 227 E 6 * 2.54 cm = 119.96 E 6 cm = 1199.6 km above the surface
