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

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.

Thus, the correct option is C.

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]

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.)

Answer:

As we know that

At STP

1 mole of any gas occupies 22.4L  

so

15.7L / 22.4L/mole = 0.7moles Cl2  

0.7moles x 6.022x10^23molecules/mole = 4.22x10^23molecules

[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)

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.

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

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.

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.

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.

Hence test each substance with red litmus paper.
