The volume of a bottle is 500cm. what is the volume of the bottle in millimeters
Answer:
5000mm
Explanation:
10mm makes 1 cm
so if we compare them:
10mm-->1cm
x -->500cm
now cross multiply:
1x-->5000
divide both sides by 1 for x to be alone
therefore we get x=5000

Answer:
The usage of gold is generally avoided in semiconductor technology, since it acts as a deep-level trap and recombination center, i.e. charge carriers of opposite sign do recombine at Au defects in Si and get lost to the current.

Since the oxidation state/number of Pb decreased, it is being Reduced.
Since the oxidation state/number of C increased, it is being Oxidized.
∴ this is a Redox Reactionplease hep!! water has a density of 1.0 g/mL. a plastic cup floats when it is placed into a container of water. what can you conclude about the density of the plastic cup? (look at the picture)
Water has a density of 1.0 g/mL. A plastic cup floats when it is placed into a container of water as it is less denser than water.
Density is a key notion in physics and material science that quantifies how tightly packed a substance's particles or molecules are within a certain volume. It is a measure of the mass contained in a certain amount of space that gives useful information about the properties of various materials.
It is vital to highlight that density is a material attribute that remains constant regardless of sample size. A little piece of iron, for example, has the same density as a huge iron block, despite the larger block having more mass.

how does our use of carbon stores affect the amount of co2 in the atmosphere?
Answer:
We are releasing the stored carbon into the atmosphere
Explanation:
We are releasing the stored carbon into the atmosphere, thus increasing the amount of CO2 in the atmosphere. We are releasing the carbon stores faster than they can be replenished by nature.
Our use of carbon stores increases the amount of carbon dioxide in the atmosphere.
What are carbon stores?Carbon stores are those places present in the environment in which carbon is present in its different composition.
As it is present in the soil in the form of organic molecules and as a deposit in the sedimentary rocks of earth such as limestones, dolomite and in the deep oceans. If we uses these carbon stores then as a result carbon dioxide releases in the environment and increases its level.
Hence amount of carbon dioxide increases.

Anapahase- chromatids are pulled apart to opposite poles
Telophase- cell about to/is divided into two
Potential energy is energy that is stored in an object. It isn't being used at the moment, but is waiting to do work. A good example is to think about a boulder sitting on top of a hill. Just sitting there, the boulder isn't doing anything. But because it is sitting on top of a hill, it has the potential to roll down and do some damage to a car or building below. The energy is stored in that rock because of its size (mass) and the distance it will travel once it starts rolling. Another good example is a rubberband. When you stretch a rubber band, it wants to move back to its original position, and thus you have given it potential energy. As the rubber band is released, potential energy is changed to motion.
Kinetic energy is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy. This energy is performing work. Other examples of kinetic energy include: legs pump bicycle pedals, lightning snaps trees, cars travel down the street, football players making tackles, and 4-wheelers speeding through the woods.
Potential energy is converted into kinetic energy. As mentioned before, a stretched rubberband can change from having potential to kinetic energy. Another example of this change between kinetic and potential energy can be seen using a yo-yo. Before a yo-yo begins to fall from your hand it has stored energy due to its position. At the top (in your hand) it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been completely converted into kinetic energy so that it now has its maximum kinetic energy. Another example of the change between kinetic and potential energy is a waterfall. A waterfall has both potential and kinetic energy. The water at the top of a waterfall has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy is used in Niagara Falls, Canada to provide electricity to parts of the northeastern United States.
