How does nuclear fission of Uranium - 234 result in electricity being generated?

Answers

Answer:

See explanation

Explanation:

The use of Uranium - 234 to generate electricity depends on a fission reaction. The uranium nuclide is bombarded by fast moving neutrons leading to a chain reaction. Control rods and moderators are used to keep the nuclear reaction under control.

As the nuclear reaction proceeds, heat is generated and steam is consequently produced. This steam is used to turn a turbine and electricity is thereby generated.

Two balls collide on a pool table. Before the collision, ball 1 is traveling with a speed of 4 m/s, and ball 2 is at rest. After the collision both balls are in motion.
What has happened in this collision?

A. There was no change in ball 2's velocity, therefore momentum was not conserved.

B. Ball 2's velocity decreased, and it gained some of ball 1's momentum.

C. Ball 1's velocity decreased, and it gained momentum.

D. Ball 2's velocity increased, and it gained some of ball 1's momentum.

Answers

Answer:

D

Explanation:

With the collision, obviously Ball 2's velocity increased, while Ball 1 slowed down a little bit due to the impact. This decrease in velocity caused a decrease in Ball 1's Momentum. Satisfying both conditions, option D is right.

When an aqueous solution of silver nitrate is
mixed with an aqueous solution of potassium
chloride which are the spectator ions?

Answers

Answer:

[tex]K^{+}[/tex] and [tex]NO_{3}^{-}[/tex]

Explanation:

The equation for the reaction is AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq)

With all the ions, it is

[tex]Ag^{+}[/tex](aq) + [tex]NO_{3} ^{-}[/tex](aq) + [tex]K^{+}[/tex](aq) + [tex]Cl^{-}[/tex](aq)  ==> AgCl(s) +

[tex]K^{+}[/tex] and [tex]NO_{3} ^{-}[/tex] do not change, so they are the spectator ions and are removed

The ionic equation is:

[tex]Ag^{+}[/tex](aq) + [tex]Cl^{-}[/tex](aq) ==> AgCl(s)

A researcher is trying to identify whether household substances are basic. Which approach would BEST help the researcher
investigate whether substances are basic?
O A. Mix each substance with a weak base and record the results.
OB. Test each substance with red litmus paper.
O C. Observe each substance and record its color.
OD Test each substance with blue litmus paper.

Answers

Answer:

I think B

Explanation:

Red litmus paper is used more to find bases, blue litmus paper changes better when coming to find acids. So I believe it is B

The best approach best investigate whether substances are basic is to test each substance with red litmus paper.

What is basic compound?

Basic compounds are those which have a pH value in between the range of 7.1 to 14.

Red litmus paper changes its color from red to blue when comes in the contact of basic compounds. So to check the basicity of household substance we should use red litmus paper.

Bases are reacting with only acids means bases shows no reaction with base and if we use weak base then we will not get the desired result as weak bases are partially dissociates only.Color will not gives idea about basicity and acidity.Red litmus paper is used to test the acidity of substance as it turns blue when comes in contact of acids.

Hence test each substance with red litmus paper.

A truck has a kinetic energy of 1200j and is traveling at 9 m/s what is the truck mass

Answers

Answer:

Mass of truck = 29.62 kg (Approx.)

Explanation:

Given:

Kinetic energy = 1200 J

Speed of truck = 9 m/s

Find:

Mass

Computation:

The kinetic energy of a thing is the force that has attributable to its movement in physics.

Kinetic energy = [1/2][m][v]²

1,200 = [1/2][m][9]²

1,200 = [1/2][m][81]

Mass of truck = 29.62 kg (Approx.)

A gaseous mixture contains 5.0 moles of nitrogen and 10.0 moles of helium . What is the total pressure if the temperature is 25 degrees C and the volume is 3.0 L? a) 122 atm
B) 56 atm
d) 2.0 atm
C)3.0 atm

Answers

Answer:

A) 122 atm

Explanation:

PV = nRT

Solve for P --> P = nRT/V

n = 10.0 mol + 5.0 mol = 15.0 mol

R = 0.08206 L atm / mol K

T = 25 + 273 = 298 K

V = 3.0

P = (15.0)(0.08206)(298) / (3.0) = 122 atm

If the temperature remains constant and pressure is INCREASED on gas, what will happen to the volume?


The volume will increase.
The volume will decrease.
The volume will not change.
The volume will randomly increase and decrease, and keep doing this.

If 0=30° then verify that sin20=2sin0.cos0

Answers

Answer:

It is proved that sin20=2sin0.cos0

Explanation:

Given

[tex]0=30[/tex] °

[tex]sin20=2sin0.cos0[/tex]

Substituting the value of "0" on both the sides, we get -

[tex]sin2 (30) =2sin 30 * cos 30\\sin 60 = 2 * sin 30 * cos 30 \\0.866 = 2 * 0.5 * 0.866\\0.866 = 0.866[/tex]

Since LHS = RHS

we can say that [tex]sin20=2sin0.cos0[/tex]

Jet streams can cause warmer air temperatures on coastal land areas when the tide changes direction.

What are jet streams?

Jet streams are short bands of high wind that travel across the globe from west to east.

On earth, the location of the jet stream is in the latitude of the tropopause.

Two polar jet streams are present near the north and south poles.

Two subtropical jet streams are present, closer to the equator,

These make the Earth's four principal jet streams.

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are;

1. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

2. Liquid: it is the state of matter in which the physical substance can be poured and it takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

3. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Filling the missing words (texts) of the question, we have;

Solids tend to be dense and difficult to compress. They do not flow or take the shape of their containers, like liquids do, because the particles in solids vibrate around fixed points. When a solid is heated until its particles vibrate so rapidly that they are no longer held in fixed positions, the solid melts. The melting point is the temperature at which a solid changes to a liquid. The melting and freezing point of a substance are at the same temperature. In general, ionic solids tend to have relatively high melting points, while molecular solids tend to have relatively low melting points. Most solids are crystalline. The particles are arranged in a pattern known as a crystal lattice. The smallest subunit of a crystal lattice is the unit cell. Some solids lack an ordered internal structure and are called amorphous solids.
