The average rainfall varies from place to place. However, the average rainfall is about 10-20 inches.

Rain fall refers to a situation in which the water that is found at the surface of the earth is evaporated, condenses in the atmosphere and then falls again to the surface of the earth as precipitation or rainfall. It is an essential component of the water cycle.

We know that the average rainfall varies from place to place. However, the average rainfall is about 10-20 inches.

Answer:

D. Provides higher resolution images

Explanation:

The advantages gained by the use of digital data transmission instead of analog transmission are;

1) Noise do not damage digital signal transmission but they impact on analog signals. Digital signals are therefore more secure than analog signals

2) The bandwidth required for digital signal transmission is much less than the bandwidth required for analog

3) Digital signal allow data transmission to very long distance

4) The rate of transmission with digital signals is higher with digital signals

5) Digital signals allow easy and cost effective methods by which they are  replicated

The resolution of an image is a measure of the amount of pixels displayed per inch of the image, such that a high resolution image has more pixel per inch of the image. It is therefore a factor determined at the source of the image based on how much detail is required in an image before transmission

I believe the answer is A (changes in air temperature  result in differences in air pressure which causes wind). Hope this helps

Explanation:

Answer:

From Pressure Law

P1/T1 = P2/T2

Changing our temp to kelvin

T1 = 47 +273 = 320K

We're looking for T2

Making T2 the subject

T2 =P2 x T1 / P1

= 655 x 320/850

T2 = 246K

Answer:

No because it's located inside the nucleus of the atom

Answer:

Tipo de enlace enlace en CO2 - Covalente

Tipo de enlace enlace en KCl - iónico

Tipo de enlace enlace en H2O: enlaces covalentes y de hidrógeno

Electronegatividad de CO2 - Diferencia en electronegatividad de carbono (EN = 2.5) y oxígeno (EN = 3.5) = 3.5 - 2.5 = 1

Diferencia en electronegatividad de KCl = 3,2 -0,8 = 2,4

Diferencia en electronegatividad de H2O = 3.5 -2.1 = 1.4

Explanation:

Avogadro's number like the name suggests is a constant that states how many atoms/molecules are in one mole of anything.

Answer:

Metal

Non-metal

Explanation:

Ionic compounds are said to be formed when metals donate electrons to non metals.

The metals become positively charged while the nonmetals become negatively charged.

CaF2 is composed of Ca^2+ and F^-. Calcium is a metal of group 2 in the periodic table while F is a nonmetal of group 17 in the periodic table.

Hence CaF2 is composed of a metal and a nonmetal.

Explanation:

number of moles = number of particle/ 6.02X10^23

= 12.044 X 10^24/6.02×10^23

=20.0066 moles so round it up to 3 S.F

So

=20.0moles

Answer:

electric charges.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction.

An electron can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

An electric current is produced when electric charges (electrons) move continuously and it's measured in Amperes through the use of an ammeter.

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.
