Answer:
"The higher the spring constant, the stiffer the spring. The spring constant is not the same value for different elastic objects. For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles."

Explanation:
Photosynthesis is the process by which green plants take in carbon dioxide and water, in the presence of chlorophyll by using sunlight to make their own food, is called as photosynthesis.
Oxygen is released as a by product.
The formula for photosynthetic reaction is :-
[tex]\sf 12H_2O + 6CO_2 \underset{chlorophyll}{\xrightarrow{Sunlight}} C_6H_{12}O_6 + 6H_2O + 6O_2 \uparrow[/tex]
Why do hot packs and cold packs eventually return to room temperature?
Answer:
Temperature will revert to room temperature after the substance reacts fully. Heat energy flows between the chemical bonds of the added substance and water to the surroundings (elsewhere in the water, the beaker, a student's hand that touches the beaker).
Explanation:
Hot packs and cold packs eventually return to room temperature because of thermal equilibrium
Temperature is the degree of hotness or coldness of a body. We have to note that bodies often tend to attain thermal equilibrium with the surroundings. Hence heat flows from or to the body as required.
Hence, the need to attain thermal equilibrium with the environment is the reason why hot packs and cold packs eventually return to room temperature.

Which of the following reactions is NOT properly classified?
Answer:
I got B a little while back, but the answer might be different for you
sorry if i am wrong
Explanation:
The chemical equation which is not properly classified is CO₂ + 2 H₂O[tex]\rightarrow[/tex] CH₄ + 2 O₂ as this is not combustion reaction.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

8 If the initial pressure of a 2.00 L gas sample is 2.50 atm, what will the pressure be if the volume is changed to 3.00 L at constant temperature?
Answer:
1.67 atm
Explanation:
Boyle's Law relates pressure and volume with the following equation:
[tex]P_{1} V_{1} = P_{2} V_{2}[/tex]
We are given 3 of the four variables in the equation, and are asked to find the final volume. Therefore:
P1 = 2.50 atm
V1 = 2.00 L
P2 = ???
V2 = 3.00 L
We substitute our variables into the equation and solve for our unknown:
(2.50atm)(2.00L) = (P2)(3.00L)
(2.50atm)(2.00L)/(3.00L) = (P2)
5/3 = 1.67atm
This supports Boyle's Law, which tells us that pressure and volume of a gas are inversely proportional. The volume increased by 1/3, so the pressure decreased by 1/3.

Stimulus refers to events that produce a response in the body due to changes in the environment , therefore response to stimulus is essential for an organism to survive and adapt in its environment.
What is a stimuli?A stimuli is any sensation or action that produces a response in a tissue or organ.
Stimulus is the plural noun of stimuli.
There are two types of stimulus:
external stimulus which comes from outside the body internal stimulus which comes from within the body.The body responds to stimulus in order to adapt to changes in both its external and internal environment.
For example, when the envrionment is hot, the brain receives stimulus from heat receptors and then we start to sweat in order to cool down.
Stimulus are received by sense organs in the body
There are five sense organs in the body;
eye - for sightear - for hearing nose - for smellingskin - for feeling mouth - for tastingSensory receptors in sense organs receives stimulus and send it to the brain through the sensory neurons.
The brain processes the stimulus and send messages back through motors neurons to appropriate organs and tissues to act in response to the stimulus.
Therefore, response to stimulus is essential for an organism to survive and adapt in its environment.

Which of these layers is found directly above the Earth's core?
Group of answer choices
Outer core
Mantle
Inner core
Crust
Answer: Mantle
Explanation:
there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.
Answer:
The answer depends on what you are taking about: the outer core or the inner core?
Answer: Mantle
Explanation:
If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer. However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.
I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.
