10pts} If a ball is thrown straight up into the air with a velocity of 15 m/s. How many seconds will it take for the ball to reach its peak? (Assume no air friction and g = -9.81 m/s²)

Please give the most detailed answer. I need reasoning as well. Brainliest to the person who gives the best answer

Answers

Answer 1

Answer:

-81.2361 m/s

Explanation:

15 m/s                                               15 m/s

- 9.81 m/s^2= 96.2361                      - 96.2361

Answer 2

It will take for the ball to reach its peak 81.2361 m/s if a ball is thrown straight up into the air with a velocity of 15 m/s.

15 m/s                                              

- 9.81 m/s^2= 96.2361            

Which formula has been used for change in velocity?

Use the formula for change in velocity equal the acceleration times the time, considering that the only acceleration acting is that of "g" (g = 9.8 m/s^2). Consider also that at the top of the trajectory is when the velocity becomes zero and the motion changes from upwards to downwards.It takes the tennis ball approximately 0.78 seconds to reach the maximum height.

Calculate the ball's greatest height using the vertically modelling method, h = -16t2 + vt + s, where v is just the initial velocity at feet/second and s is indeed the height in feet.

Zero The ball travels upward when you throw it, but because gravity is pulling on it, its speed diminishes as it ascends.The ball begins to slow down, and during the peak of its journey, it has zero velocity.

Therefore, It will take for the ball to reach its peak 81.2361 m/s if a ball is thrown straight up into the air with a velocity of 15 m/s.

15 m/s                                              

- 9.81 m/s^2= 96.2361

Answer:

Asteroids are objects made of clay and silicate  that orbit the sun but are too small to be considered planets.

Most asteroids revolve around the sun in an orbit between those of Mars and Jupiter.

They form a wide band called the Asteroid belt.

Other asteroids have orbits that cross Earth’s orbit. These asteroids are called  Earth-crossers.

What information is used to determine earthquake risk?

Answers

Answer:

There are several pieces of information that are used to determine earthquake risk:

Seismic data: This includes information about the frequency, size, and location of earthquakes that have occurred in a particular area. This can help scientists understand the likelihood of future earthquakes and how strong they are likely to be.

Geological data: This includes information about the geology of an area, including the types of rocks and soil present, the structure of the Earth's crust, and the presence of fault lines or other features that may affect the likelihood of earthquakes.

Population data: The number of people living in an area can also be a factor in determining earthquake risk, as a larger population is more likely to be affected by an earthquake than a smaller one.

Building data: Information about the types and condition of buildings in an area can also be used to determine earthquake risk, as buildings that are poorly constructed or not designed to withstand earthquakes are more likely to be damaged or collapse.

Insurance data: Insurance companies may also use data about past earthquakes and their effects to help assess the risk of future earthquakes in an area.

Overall, the risk of earthquakes is determined by a combination of these and other factors, and it can vary significantly from one location to another.

Answer:

In order to determine earthquake risk, information on the density of buildings and people (exposure), the vulnerability of the built environment, and robust earthquake hazard assessments, including the impact of local soil conditions, are needed.

If Neptune’s mass were reduced, what could be done to maintain the same force of gravitational attraction between Neptune and the Sun?

Answers

Make Neptune closer to the sun because then it would have a stronger gravitation pull. Because the closer the objects are, they will have a stronger gravitaional force and when the object has more mass, the gravity is also stronger. So, if the mass is reduced, the gravity force would be reduced, but if you bring neptune closer, the gravity force would increase

this is because if we multiply both by 6, we get 60 and 36 minutes but we cant have 36 minutes since it has to be 60 so we can get mph so we would have to multiply both by 10 makeing the time 60 and the kilometers 100 and 60 minus 100 is 40

What change does this cause concerning weather?

Answers

Answer:

More extreme weather.

Explanation:

The Conveyor Belt of tides functions on a local and global level to spread out the cold and hot temperature differences on the planet. It is a delicate but important process that is easily disrupted, which causes it to slow down. And when it slows down, all those temperature differences will become more concentrated, causing colder places to be colder and hotter places to be hotter, ultimately leading to more extreme weather events as these cold and hot spots collide more violently than before.

Here's a picture I found on it:
