Answer: Helianthus L. Sunflower

Explanation:

Answer: Helianthus L.

Explanation:

Answer:

South of San Bernardino has more earthquakes because they have about 10,000 in a year but Cajon has about 160 earthquakes in a year therefore south San Bernardino earthquakes most didnt really damage places so 100 plus magnitude of 3.0 and only 15-20 are greater magnitude of 4.0. Cajon has less earthquakes a year and not big magnitude damages as South of San Bernardino so as you can see here we have South of San Bernardino earthquakes rising each and every year.

Answer:

fixed resistors, variable resistors, resistance dependent on a physical quantity

Answer:

True

Explanation:

The bigger mass is measured in kilograms and smaller in grams

Answer:

Increase the concentration of the reactants.

Explanation:

This question seems vague, but to put it simply, the reaction rate decreases with a decrease in temperature, so we need to find a way to increase the reaction rate again. When you lower temperature, the molecules are slower and collide less. So therefore, in other words, we need to find a way to increase the rate of collisions between molecules. When the temperature drops, if we increase the concentration of the reactants, we are able to increase the rate of collisions between molecules. As a result, reaction rate is increased once again.

If the temperature of a chemical change was reduced,the reaction rate could most likely be increased by increasing the concentration of the reactants.

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

Answer:

See the answer below

Explanation:

The cell represents the basic unit of life and any living organism.

One example of specialized cells in the body are the sex cells.

The sex cells are primarily concerned with reproduction and perpetuation of life. The cells undergo meiosis to produce haploid gametes. Male and female gametes then fuse together during fertilization to give rise to diploid zygotes which eventually give rise to new organisms.

Answer:

3.7 L

Explanation:

Initial volume (V₁) = 3.3 L

Initial pressure (P₁) = 100 KPa

Final pressure (P₂) = 90 KPa

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P₁V₁ = P₂V₂

100 × 3.3 = 90 × V₂

330 = 90 × V₂

Divide both side by 90

V₂ = 330 / 90

V₂ = 3.7 L

Thus, the final volume of the gas is 3.7 L

Wind direction is reported by the direction from which it originates. For example, a north or northerly wind blows from the north to the south. Wind direction is usually reported in cardinal (or compass) direction, or in degrees.

The features of the ocean floor are not permanent, and are gradually changing over time due to the movement of tectonic plates. Most of the ocean floor features from close to where the plates are shifting either towards or away from each other. Marine ecosystems are found around parts of the ocean floor features, even the Mariana Trench, which is the deepest trench in the world.

Answer:Resistor Basics

Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit.

They are passive components, meaning they only consume power (and can't generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines.

Resistor units

The electrical resistance of a resistor is measured in ohms. The symbol for an ohm is the greek capital-omega: Ω. The (somewhat roundabout) definition of 1Ω is the resistance between two points where 1 volt (1V) of applied potential energy will push 1 ampere (1A) of current.

As SI units go, larger or smaller values of ohms can be matched with a prefix like kilo-, mega-, or giga-, to make large values easier to read. It's very common to see resistors in the kilohm (kΩ) and megaohm (MΩ) range (much less common to see miliohm (mΩ) resistors). For example, a 4,700Ω resistor is equivalent to a 4.7kΩ resistor, and a 5,600,000Ω resistor can be written as 5,600kΩ or (more commonly as) 5.6MΩ.

Schematic symbol

All resistors have two terminals, one connection on each end of the resistor. When modeled on a schematic, a resistor will show up as one of these two symbols:

Resistor schematic symbols

Two common resistor schematic symbols. R1 is an American-style 1kΩ resistor, and R2 is an international-style 47kΩ resistor.

The terminals of the resistor are each of the lines extending from the squiggle (or rectangle). Those are what connect to the rest of the circuit.

The resistor circuit symbols are usually enhanced with both a resistance value and a name. The value, displayed in ohms, is obviously critical for both evaluating and actually constructing the circuit. The name of the resistor is usually an R preceding a number. Each resistor in a circuit should have a unique name/number. For example, here's a few resistors in action on a 555 timer circuit:

Answer: resistor is

Explanation:

A resistor controls the flow of the electrical current within a circuit. Resistors are made from materials like copper or carbon, which make it difficult for the electrical charges to flow through a circuit. The most common type of resistor is a carbon resistor, which is a general purpose resistor, best suited for lower-powered circuits.

Answer:

Cloud form

Explanation:

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. ... Once water evaporates, it also helps form clouds.

I do NOT agree with that statement; photosynthesis and cellular respiration are simply two different processes. This does not mean that they are necessarily opposites. However, their chemical reaction-equations are opposite of each other. The processes themselves are similar.

Answer:

A. 6atm

Explanation:

Using pressure law equation:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)

T1 = initial temperature (K)

P2 = final pressure (atm)

T2 = final temperature (K)

According to this question;

P1 = 3 atm

P2 = ?

T1 = 120K

T2 = 240K

Using P1/T1 = P2/T2

3/120 = P2/240

Cross multiply

240 × 3 = P2 × 120

720 = 120P2

P2 = 720/120

P2 = 6atm

Answer: 0.245 m/s

Explanation:

So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s
