Which of the following states of matter is always a good conductor of electricity? solid, liquid, gas, or plasma **:/ Thank you!

Answers

Plasma...I believe is always a good conductor of electricity. I was tempted to say a solid, but not all solids are the same in composition and that goes for liquid and gas as well.

Hopefully this helped and good luck.

Which of the following is a possible use for nuclear energy?a. power plants
b. weapons
c. powering submarines
d. all of the above

Answers

Nuclear energy can be used to power all ofthe above choices. Nuclear power plants produce radioactive waste that must bestored properly. It is very impossible for a nuclear power plant to have nowaste at all since lots of chemicals are used to create the process as it givesenergy to other machines, weapons such as bombs and  powering submarines.  Radioactive waste can not be released intolocal water supplies since the wastes are very radioactive and may causemutation to the fishes and bioaccumulation which will affect humans as well. Itwill also cause air pollution if the chemicals are not stored properly.

D. All of the above. you're welcome

Explanation:

There are several measures for the international system of measures. Let's name some and their representation symbol.

meter = [m]

time = [s] = seconds

mass = [kg] = kilograms

Temperature = [°C] = celcius degrees

Power = [W] = watts.

Force = [N] = Newtons

6 questions:What percentage of the earth is covered by water?

Did dinosaurs and humans ever exist at the same time?

What is Darwin's theory of the origin of species?

Why is the sky blue?

What causes a rainbow?

Why does a year consist of 365 days and a day of 24 hours?

Answers

For question 1: What percentage of the earth is covered by water?

Your answer for question 1:
About 71 percent of the earth's surface is covered by water.

For Question 2:
Did dinosaurs and humans ever exist at the same time?

Your answer for question 2:
No. Dinosaurs went extinct at the end of theCretaceous period, 65 million years ago. Modern humans did not appearuntil around 200,000 years ago.

For question 3:
What is Darwin's theory of the origin of species?

Your answer for question 3:
Darwin's theory of species origination says thatnatural selection chooses organisms that possess variable and heritabletraits and that are best suited for their environments.

For question 4:
Why is the sky blue?

Your answer for question 4:

Solar radiation sunlight is scattered across theatmosphere by a process called diffused sky radiation. The sky is bluebecause much more short-wave radiation, blue light, is scatteredacross the sky than long-wave radiation, red light.

For question 5:
What causes a rainbow?

Your answer for question 5:
Rainbows can be seen when there are water droplets in theair and the sun is shining. Sunlight, which contains all colors, isrefracted, or bent, off the droplets at different angles, splittinginto its different colors of red, orange, yellow, green, blue, indigoand violet.

For question 6:
Why does a year consist of 365 days and a day of 24 hours?

Your answer for question 6:
A year, 365 days, is the time it takes for the Earth totravel around the Sun. A day, 24 hours, is the time it takes for theEarth to spin around once on its axis.

Suppose that now you want to make a scale model of the solar system using the same ball bearing to represent the sun. How far from it would you place a sphere representing the earth? (Center to center distance please.) The distance from the center of the sun to the center of the earth is 1.496×10111.496×1011 m and the radius of the sun is 6.96×1086.96×108 m.

Answers

In this exercise we have to use the knowledge in distance, in this way we will find that the proportional distance found is:

d = 0.645 m

So from the information given in the text we find that:

  • The distance from the center of the sun to the center of the earth is 1.496*10^(11) \ m
  • The radius of the sun is 6.96*10^(8)m
  • We need to assume a radius for the ball bearing, so suppose that the radius is 3 mm  

First, we need to find in what way or manner often the radius of the brightest star exist considerable respect to the range of the ball significance, that exist given apiece following equating:

(r_a)/(r_b)= \frac{6.96*10^8}{3*10{-3}}  =2.32*10^(11)

Now, we can calculate the distance from the center of the sun to the center of the sphere representing the earth:  

d_(s) = (d_(e))/(r_(s)/r_(b)) = (1.496 \cdot 10^(11) m)/(2.32\cdot 10^(11)) = 0.645 m

See more about distance at brainly.com/question/989117

Answer:

d = 0.645 m(assuming a radius of the ball bearing of 3 mm)

Explanation:

The given information is:

  • The distance from the center of the sun to the center of the earth is 1.496x10¹¹m = d_(e)
  • The radius of the sun is 6.96x10⁸m = r_(s)

We need to assume a radius for the ball bearing, so suppose that the radius is 3 mm = r_(b).  

First, we need to find how many times the radius of the sun is bigger respect to the radius of the ball bearing, which is given by the following equation:

(r_(s))/(r_(b)) = (6.96\cdot 10^(8)m)/(3\cdot 10^(-3)m) = 2.32\cdot 10^(11)

Now, we can calculate the distance from the center of the sun to the center of the sphere representing the earth, d_(s):  

[tex] d_{s} = \frac{d_{e}}{r_{s}/r_{b}} = \frac{1.496 \cdot 10^{11} m}{2.32\cdot 10^{11}} = 0.645 m

an electron is held at a distance from a stationary, positively charged object . If the electron is released , what energy change will take place?

Answers

Answer:

Electrostatic potential energy will convert into kinetic energy

Explanation:

When electron is released from rest at some distance from positive charge then due to electrostatic attraction force these two charges will attract each other.

Now in the form of energy we can say that

electrostatic potential energy = (kq_1q_2)/(r)

now as the two charges comes closer to each other then the electrostatic potential energy will decrease and hence this energy will convert into kinetic energy of two charges

so we can say

(kq_1q_2)/(r_2) - (kq_1q_2)/(r_1) = (1)/(2)mv^2

Electric potential energy will be transformed into kinetic energy.
