1. Describe and explain all the possible energy transformations that occur with a dishwasher that uses electrical energy.
2. Discuss the different observations that you would record during an investigation into the energy transformations of a lamp that uses electrical energy.
Answers
Answer:
1. All the possible energy transformations that occur with a dishwasher that uses electrical energy are heat energy because the dishwasher uses the electrical energy to heat the water, also electrical energy is transformed into kinetic energy and sound energy the reasoning behind this is that the parts moving inside the dishwasher is causing the sound.
2. Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.

Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

How do genetic factors influence the formation of "dead zones” around creosote bushes?
Answers
Answer:
Genetic factors contributes to the formation of the dead zones is by their ability to expand their abilities that enables them to spread and contribute to the formation of the dead zones. These dead zones are made when the oxygen are low where it is necessarily important for the aquatic life, if the oxygen needed is depleted or too low, instead of supporting aquatic life, dead zones are created and factors contribute to these occurrences with their ability to expand.
Explanation:
Answer:
The creosote bush has genes that give it the ability to capture and hold water. These plants have developed a root system that is very good at absorbing water, preventing them from being crowded by other desert plants. Seeds that fall nearby cannot get enough water to sprout. This creates dead zones around every creosote bush.

4. What happens to the land between 600 feet above sea level and the lake?
Answers
To solve this we must be knowing each and every concept related to sea level measurement. Therefore, between 600 feet above sea level and the lake, temperature starts to decrease as well as the pressure, which affects the winds etc.
What is sea level measurement?The surrounding terrain is used to determine the sea level. The selling of electronic products is referred to as "electronic commerce." For instance, a glacier's massive weight on land causes the land to be pushed lower and nearer to sea level.
Between 600 feet above sea level and the lake, temperature starts to decrease as well as the pressure, which affects the winds, influence the ocean currents, lake discharges for lake etc.

Which of the following problems would be a direct result of humans building along the ocean shore zone?
A. the erosion of the sand and soil from the shoreline
B. sand dunes and vegetation being disturbed
C. the movement of sand from one place to another
D. sand being washed away over long periods
Answers
Answer:
I think it is B.
Explanation:
The erosion of the sand and soil from the shoreline would be a direct result of humans building along the ocean shore zone. When humans build structures along the shoreline. This can lead to increased erosion of the shoreline and loss of the beach.
Building along the ocean shore zone can have several impacts on the natural environment. One of the direct impacts is the erosion of the sand and soil from the shoreline. This occurs because construction can disrupt the natural processes that maintain the beach, such as the movement of sand and the protection provided by vegetation.
For example, building seawalls or other structures can prevent the natural movement of sand and sediment along the beach. This can lead to erosion of the shoreline, as the sand is no longer able to accumulate in areas where it is needed to protect the shoreline. These plants help to hold the sand in place and protect the beach from erosion.

Based on evidence from Sim, when two substances were combined they did not change into different substances.
Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.
They just combine together and form a new substance.
Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.
The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.
Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.
If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.
It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
