In many environments, the temperature of the ground and the air right above the ground are both very similar in the middle of the night. Engineers have proposed developing a portable pop-up hammock that would allow people to sleep suspended in the air above the ground in emergencies. It will take time and money to develop a really lightweight, easy to collapse, low cost design. Before they invest the resources to do this, explain whether what you learned about energy transfer makes this an idea worth pursuing. Would suspending a person in a hammock, wrapped in one of the blankets you chose above, decrease the amount of temperature change compared to sleeping directly on the ground with one of these blankets? Explain.
Answer:
yes i think so
Explanation:
Hammock is a good idea to reduce the effect of cold in night. It is more better than sleeping directly on the ground with one of these blankets, because, the heat will transfer from us to the cool ground which make us more cool.
What is heat transfer?Heat is able to transfer from the hotter region to colder region based on the temperature gradient. The temperature gradient occurs from the difference in heat radiated in each regions.
The convection current in air occurs due to this temperature gradient. During winter seasons, the colder grounds can absorbs the heat from our body and make us cool. Thus, contact with the ground in colder nights make us more cool.
The same advantage of air circulation around your body on warm nights is provided by a nylon hammock. Additionally, a cozy under blanket (like this one from Cedar Ridge or this one from Little Shop of Hammocks) will keep your backside warm when the weather drops.

Which part of the ear converts vibrations into nerve impulses?
cochlea
auditory nerve
outer ear
eardrum
Answer:
cochlea
Explanation:
The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

How do planets with larger masses apply greater gravitational forces on objects compared to planets with less mass?
Answer:
more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Explanation:
True or False. The elements that make up the reactants must be present in the products.
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.

Answer:
Potential,Kinetic
Explanation:
When an object is higher up on a surface it has more Gravitational Potential Energy whilst when an object is lower down but moving fast it has more kinetic energy. So when the object moves down the ramp energy is transferred from the gravitational potential energy store to the kinetic energy store.

Which option correctly describes the pattern of valence electrons on the periodic table?
O The number of valence electrons increases from right to left
O The number of valence electrons increases from bottom to top.
O The number of valence electrons increases from top to bottom
O The number of valence electrons increases from left to right.
Answer:
O The number of valence electrons increases from left to right.
Explanation:
In general, the number of valence electrons is the same within a column/group. When the group number increases, the # of valence electrons also increases.
The option correctly describes the pattern of valence electrons on the periodic table is the number of valence electrons increases from left to right. Thus, option D is correct.
What is atomic mass?In universe every particle have some mass associated with it whether it is small or large. According to Dalton's theory of atomic structure every particle is made up of with atoms. The average mass of atomic particle is called as atomic mass. This is commonly calculated as per international agreement in terms of a unified atomic mass (amu).
It can also be defined as 1/12 of the mass of a carbon atom-12 in its ground state. The mass of atom can also be calculated as the mass of protons and neutrons which almost equal to atomic mass. This small change is due to the binding energy mass loss.
Calculation:-
As per given above question:-
99% H-1
0.8% H-2
0.2% H-3
So,
Atomic mass = (99x1 + 0.8x2 + 0.2x3)÷100%
Atomic mass = 1 amu,
Therefore, The option correctly describes the pattern of valence electrons on the periodic table is the number of valence electrons increases from left to right. Thus, option D is correct.

Part D
Provide a brief explanation whythe investigation measurements differed.
Answer:
part b:
Sodium bicarbonate is a white, crystalline powder that sometimes forms lumps. It is odorless and has a bitter, salty taste. At room temperature, it is a solid. Solubility, or the ability of a substance to dissolve in water, is also a physical property. Sodium bicarbonate is soluble in water and can be separated from water through evaporation.
Explanation:
In the reaction of baking soda with acetic acid carbon dioxide gas is evolved that's why the balloon inflates. The mass in the product side and reactant side ar equal and the the total mass is conserved.
What is mass conservation?According law of conservation of mass, mass can neither be created nor be destroyed. Therefore, the total mass of a system will be conserved. In a chemical reaction, the total mass of reactants is equal to the total mass of products and thus no mass loss occur there.
In the reaction of vinegar (acetic acid) and sodium bicarbonate or baking soda, the mass on both side is equal and we get the product mass equal to the total mass of reactants if the experiment is carefully done.
Sodium carbonate is a colourless weak base, which can easily react with an acid and gets protonated. When sodium bicarbonate that is NaHCO₃, with vinegar CH₃COOH, it will produce carbon dioxide and water.
This carbon dioxide gas evolves to the balloon which is stretched on the top and the balloon will inflates.The measurements will differ at each moment because we are measuring it in different events of the reaction where the gas is evolving out.
