Answer:
the total resistance is 12 ohms
Amps = 1 amp
Explanation:
resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1
1 amp
resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1 is the correct answer
describe the water cycle here on Earth and explain how it demonstrates the law of conservation of matter.
Answer:
Start with evaporation. Place a full cup of water in front of a sunny window. Use a marker to make a line at the beginning water level.
After evaporation we have condensation. When the water vapor reaches the sky it cools to form clouds.
Finally, a precipitation experiment. Again, fill a cup almost full with water.
Explanation:
Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.

How important is it for a cell to maintain the same number of chromosomes? Explain.
Answer:
It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct?
Brody is correct because the wave involves an input of energy.
Ethel is correct because energy is not carried from one place to another.
Brody is correct because the pattern repeats.
Ethel is correct because the motion has no pattern.
Ethel is correct because energy is not carried from one place to another.
What is a wave?A wave is a disturbance along a medium which transfers energy. We have to know that wave moves from place to place and must transfer energy in the process.
In this case, Ethel is correct because energy is not carried from one place to another as Broody waves his hand from side to side.

Utah has the largest concentration of oil shale and tar sands in the United States. Which statement identifies a disadvantage to this location?
The statement that effectively recognizes the disadvantage of the given location would be:
b). The contamination of nearby bodies of water could occur.
The disadvantage of the location of the maximum congregation of oil shale and tar sands could be the pollution that it can cause to the water bodies that exist in the nearby area. This pollution can affect aquatic life(plants and animals) and the people residing there as well.The mixture of various components like clay, bitumen, sand, etc. can impact the water quality and ultimately the processes in which it is used(industries and household usage).Thus, option b is the correct answer.

a block of wood has a mass of 6 .0 and a volume of 12 .0 CM what is the density Of the block of wood
Brainly will be given
Answer:
[tex]\boxed {\boxed {\sf d=0.5 \ g/cm^3}}[/tex]
Explanation:
Density is equal to mass over volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the wood is 6.0 grams and the volume is 12.0 cubic centimeters.
[tex]m= 6.0 \ g \\v= 12.0 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac {6.0 \ g}{12.0 \ cm^3}[/tex]
Divide.
[tex]d=0.5 \ g/cm^3[/tex]
The density of the wood is 0.5 grams per cubic centimeter.

2. is a theory that states that the increasing carbon dioxide in the atmosphere is causing the climate to warm up.
Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.
