1) Would a person's weight on Earth be the same as it would be on the moon? Explain using the key words weight, mass & gravity.
Answer:
The force gravity exerts on a person determines the person's weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.

Which surface is most likely to create an echo?
a room with hard, flat walls
a room with hard, bumpy walls
a room covered in soft, wavy curtains
a room padded with soft, flat cushions
A room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.
What is echo?Echo is defined as a recurrence of sound caused by sound waves being reflected off of a wall, mountain, or other obstruction. Bats, dolphins, and fishermen all use echoes to find objects or obstructions. To find an obstruction, they are also utilized in SONAR (Sound navigation and ranging) and RADAR (Radio detection and ranging).
Buildings made of glass, metal, and concrete, the brick and metal interior of a warehouse, marble floors and buildings, or, if the room is designed in such a way that the acoustics produce an echo, plastered and painted interior walls, are examples of man-made materials that are smooth enough to produce an echo.
Thus, a room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.

when enough stress builds up in brittle rock, the rock breaks, causing a ___ to form
How do faults form? When enough stress builds up in rock then the rock breaks creating a fault. A normal fault occurs when rock is being pulled apart by tension; in this type of fault the hanging wall moves downward and the foot wall moves upward due to the tension in Earth's crust.

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.

Answer:

Explanation:
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 interaction occurs when light goes into an object as heat energy?
Answer:
Absorption. Absorption occurs when photons from incident light hit atoms and molecules and cause them to vibrate. The more an object's molecules move and vibrate, the hotter it becomes. This heat is then emitted from the object as thermal energy.

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.

Answer:

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.
think about the statement "every decision has an environmental impact"?what decision do you make that add carbon dioxide to the environment?what decision do you make that would add less carbon dioxide to the environment then you currently add?
Explanation:
Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.
Answer:
Answers may vary. View explanation.
Explanation:
There are every day decisions that may add carbon dioxide to the environment.
Problems:
Burning of fossils fuels. Example: Using cars as transportation. The average car releases around 4.6 metric tons of carbon dioxide per year.Deforestation. Carbon dioxide is released from dead organisms such as trees. Example: As of 2021, 15 billion trees are lost to deforestation.Solutions:
Instead of taking your car to work or school, carpool with a friend. Riding your bike and taking the bus are also good solutions that help minimize carbon dioxide releases.In spare your time, grab a couple of friends and plant some trees! Even planting just a few trees is a great start to help the planet.Have a great day!
