If a ball is dropped from different heights, it will take different amounts of time to hit the ground due to the force of gravity. The time it takes for an object to fall is determined by its initial height and the acceleration due to gravity.
Let's consider the three different heights mentioned in the question: the Empire State Building, the Golden Gate Bridge, and the Statue of Liberty. To calculate the time it would take for a ball to hit the ground from each of these heights, we need to use a formula.
The formula to calculate the time it takes for an object to fall is:
t = √(2h/g)
where t is the time, h is the initial height, and g is the acceleration due to gravity (which is approximately 9.8 m/s^2).
Now, let's fill in the table with the calculated times:
Dropped from: Empire State Building
Time (seconds): t = √(2h/g)
To calculate the time, we need to know the height of the Empire State Building. The Empire State Building is approximately 443.2 meters tall. Plugging in the values into the formula:
t = √(2 * 443.2 / 9.8) ≈ √(90.4) ≈ 9.51 seconds
So, it would take approximately 9.51 seconds for a ball to hit the ground if it was dropped from the Empire State Building.
Dropped from: Golden Gate Bridge
Time (seconds): t = √(2h/g)
To calculate the time, we need to know the height of the Golden Gate Bridge. The height of the Golden Gate Bridge's main towers is approximately 227 meters. Plugging in the values into the formula:
t = √(2 * 227 / 9.8) ≈ √(46.34) ≈ 6.81 seconds
So, it would take approximately 6.81 seconds for a ball to hit the ground if it was dropped from the Golden Gate Bridge.
Dropped from: Statue of Liberty
Time (seconds): t = √(2h/g)
To calculate the time, we need to know the height of the Statue of Liberty. The height of the Statue of Liberty from the ground to the tip of the torch is approximately 93 meters. Plugging in the values into the formula:
t = √(2 * 93 / 9.8) ≈ √(18.88) ≈ 4.35 seconds
So, it would take approximately 4.35 seconds for a ball to hit the ground if it was dropped from the Statue of Liberty.
Finally, if the ball is dropped from the top of a table, which is a much lower height, the time it takes to hit the ground is negligible. It would take a fraction of a second for the ball to reach the ground.
Remember, these calculations assume no air resistance and that the ball is dropped without any initial velocity.
What information is used to determine earthquake risk?
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.

Why is Christchurch, New Zealand’s air temperature cooler than usual during El Nino years?
Answer:
During normal years energy transfers from the ocean to the air. However, during El Nino years, the current is not as warm, so less energy will transfer from the current to the air, making Christchurch cooler than usual. During El Niño years, the normal prevailing winds are disrupted.

1.Where is matter found?
2. Use your five senses to describe hot buttered popcorn. (use all 5 senses) *
3. What property of matter can be observed using a pan of water? *
4. Paper clips are made of steel, which has iron in it. Do you expect paper clips to be attracted or not attracted to a magnet? Why or why not? *
5. What properties of an object would you observe when you use a metric ruler? *
6. What metric unit is used to describe the mass of an object? *
Answer:
1. Even though matter can be found all over the Universe, you will only find it in a few forms (states) on Earth. We cover five states of matter on the site. Each of those states is sometimes called a phase. There are many other states of matter that exist in extreme environments.
2. hot buttered popcorn, burns my tongue, smells buttery, looks yellowish-white, tastes like butter, and sounds like popping corn.
3. The water is a liquid so it has the same shape had the pan.
4.Paper clips are attracted to magnets because iron has a magnectic force.
5. The first (or smallest measurement) you would see is the hash marking millimeters, which is written as "mm". 1mm equals the thickness of a dime. The unit of measure that is most often displayed on a metric ruler would be centimeters written "cm". 10mm equals 1cm and 2.5cm is about equal to 1 inch. Centimeters are displayed for viewing like inches are, marked on the ruler in increments of 1, 2, 3, 4... and so on. Usually to 30cm which is slightly less than 12 inches.
6. Mass is used to measure the weight of an object. For example, you are measuring the mass of your body when you step on to a scale. In the metric system of measurement, the most common units of mass are the gram and kilogram.

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
Answer:
-81.2361 m/s
Explanation:
15 m/s 15 m/s
- 9.81 m/s^2= 96.2361 - 96.2361
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

Write a report on waves. Some questions you might consider are: What makes a wave? Why are some waves small and some large? How are waves classified? Are there different kinds of waves? What happens when a wave meets the shore? Where in the world do you find the best waves for surfing?
Answer:
The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates. Portugal is one of the best places to surf because they have waves that can reach up to 6 to 15 feet high!
Explanation:
What change does this cause concerning weather?
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.

Lauren's SUV was detected exceeding the posted speed limit of 60 kilometers per hour, how many kilometers per hour over the limit would she have been traveling if she had covered a distance of 10 kilometers in 6 minutes? (6 minutes = 0.1 hr)
40 mph
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
