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.

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.

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.

B- if the temperature increases, then crickets will chirp more.
C- I hear crickets in the summer, so crickets chirp more when it’s war outside
D- dose temperature affect how much crickets chirp?
Answer: C) Does the temperature affect how much crickets chirp
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.

Buffalo, New York is a city located near a large lake called Lake Erie. Buffalo receives an average of nearly 94 inches of snowfall a year. Using your knowledge of temperature and what you have read, explain why Buffalo receives so much snow.
Answer: it is further away from the equator
Explanation:
The simple answer to why Buffalo receives so much snow, and why it is is often confined to a specific area, is lake effect snow. Lake effect snow occurs most frequently during cold snaps in early winter. It happens when the transfer of heat and moisture from the warm waters of the Great Lakes to the cold air creates a shallow layer of atmospheric instability, causing air to rise quickly. As the moisture rises and condenses, it begins to fall as snow–and often, a lot of snow. Depending on which direction the winds are blowing, areas in the snow belts near the Great Lakes (including Buffalo) can see several feet of snow in just a few days. According to the National Weather Service, in the Buffalo area, when cold air from Canada moves over the still unfrozen, relatively warm Great Lakes, the lake moisture and instability from this temperature contrast build one or more bands of snow. These bands are then deposited over locations downwind from the lakes, with some areas receiving much more snow than others, depending on their location and the wind direction.
