A student drops a tennis ball from the top of a building as shown in the picture air resistance is negligible. Explain how the student can determine the height of the building if the kinetic Energy of the tennis ball is known when it hits the ground. And your explanation use the terms kinetic energy, gravitational potential energy, acceleration due to gravity mass and height
We can use potential energy to solve. Remember, your height and your gravity need to have the same sign, as they are moving in the same direction (downward). Either make them both negative, or use an absolute value.
Using conservation of energy, we know that PEtop=KEbottom. This tells us that the potential energy at the top of the hill is all converted to kinetic energy at the bottom of the hill. We can substitute the equations for potential energy and kinetic energy.
mgh=12mv2
The masses cancel out.
gh=12v2
Plug in the values, and solve for the velocity.

Deserts can be found near oceans on the coast of continents?.
Answer:
Yes.
Explanation:
Coastal deserts, as the name indicates, are deserts that stretch along the shore. They're one of the four primary desert varieties. Their proximity to the sea endows them with distinct characteristics not present in other deserts. Deserts like this are common on the western margins of continents, when cold ocean currents flow parallel to the shore. The air above is unable to contain moisture due to the cold currents, and the majority of it falls as rain on the sea before reaching land. As a result of the cold ocean currents, the area around the shore receives little or no precipitation and becomes a desert. Winters in coastal deserts are generally brief, with temperatures of 5°C and lower, with the lowest temperature recorded being -4°C. Summer temperatures in the coastal deserts range from 13°C to 24°C, with 35°C being the maximum ever recorded. Every year, an average of 13cm of rain is recorded. Despite their proximity to water sources, these deserts remain noticeably dry because the majority of precipitation falls in the ocean, with just a little portion reaching land. The soils in these deserts are more permeable, with a moderate texture and salt concentration. The production of strong fogs in the winter is another distinctive feature of coastal deserts. Upwelling cold currents cause such fogs to develop, which coat the desert and prevent sun rays from reaching the sands.
If someone lives in a rocky terrain, growing crops such as wheat and corn would be a challenge. It would be necessary to cultivate crops that can thrive in that type of region, such as grapes and olives. Therefore, those foods would become a staple of that person's diet, and be found in most recipes.
What is this passage an example of?
how one's religion is formed based on living conditions
how one finds transportation based on where they live
how one's culture is often determined by where they live on Earth
how one's political beliefs can be shaped by where they live
Answer:
I would say that the answer is the third option: "how one's culture is often determined by where they live on Earth".
Explanation:
Culture encompasses many aspects of one's life including their language, traditions, beliefs, and even what they eat and wear. Since living in a rocky terrain will result in the masses of people having a diet consisting of grapes and olives, they'll naturally pass down whatever recipes they've accumulated, from generation to generation.

Compare and contrast the effects of warm and cold currents on climate
Answer:
The cold currents often form when the air on the subtropical high blows over a cold mass of water, then the cold air is dragged to the equator. Warm currents, on the other hand, are large masses of warm water moving further away from the equator, at higher temperatures.
Cold ocean currents move towards the equator which forms cold air and Warm currents, on the other hand, move away from the equator resulting in formation of hot or warm air.
How do warm and cold currents affect the climate?The ocean currents act as thermal condensers, transmitting heat to tropical areas and helping tropical areas cool down, thus affecting both the weather and the climate.
Cold waves often form when hot air blows over cold water, and cold air is drawn into the equator.
Warm currents, on the other hand, are the warmest waters of the equator, at higher temperatures.
Thus, Cold ocean currents move towards the equator which forms cold air and Warm currents, on the other hand, move away from the equator resulting in formation of hot or warm air.

Hill station located in the alps in western austria.
Answer:
Tyrol
I hope this helps
Hill station located in the alps in western Austria is called Tyrol.
What is Hill station?
A town known as a hill station is one that is situated higher up than the neighboring plain or valley.
For towns established by European colonialists as escapes from the summer heat, the term "hill station" was most commonly used in colonial Asia, though it was also used in Africa.
Dale Kennedy notes that in the Indian context, "the hill station was seen as an exclusive British preserve: here it was possible to render the Indian into an outsider."
The majority of hill stations in India, which has the most of them, are located at an elevation of between 1,000 and 2,500 meters.
High refuge, high refuge to hill station, and hill station to town are the three stages Kennedy, following Monika Beuerlein, believes the development of hill stations in India went through.

A person is lost and needs to go south. how might a magnetic compass help the person?
Answer:
The compass always points north. One can use this to know which direction North is, and therefore, in which direction south is, since south is directly opposite of north.
The compass always points north. One can use this to know which direction North is, and therefore, in which direction south is, since south is directly opposite of north.
What is a compass?A compass is a device used for navigation and geographic orientation that displays the cardinal directions. It is often made up of a magnetized needle or another device, such as a compass card or compass rose, that may swivel to align with magnetic north.
The needle on the compass always points north. This may be used to determine which direction North is, and hence which way South is, because south is precisely opposite north.
