What are the 5 characteristics of volcano?

During volcanic eruptions, the chunks of solid rock blasted out of the volcano are called volcanic bombs.

Here, we have to find the initial speed of the bomb at angle θ = 42° to the horizontal so that it falls at the foot of the volcano at B, at vertical distance h = 3.40 km and horizontal distance d = 9.10 km. We need to ignore, for the moment, the effects of air on the bomb's travel. Let's calculate the initial speed required in (a).

(a) Initial speed required:To calculate the initial speed required, we can use the formula for the horizontal range of a projectile:x = v0cosθt, where v0 is the initial speed of the projectile, θ is the angle of projection, and t is the time of flight.We can also use the formula for the vertical displacement of a projectile:y = v0sinθt - (1/2)gt², where g is the acceleration due to gravity.To calculate the initial speed, we can use the following steps:At the foot of the volcano at B, the horizontal distance d = 9.10 km and vertical distance h = 3.40 km.The horizontal distance travelled by the projectile, x = 9.10 km = 9100 m.

The vertical distance travelled by the projectile, y = 3.40 km = 3400 m.The angle of projection, θ = 42°.The acceleration due to gravity, g = 9.8 m/s².We can use the formula for y to find the time of flight, t:y = v0sinθt - (1/2)gt² => 3400 = v0sin42°t - (1/2)(9.8)t²We can use the formula for x to find the initial speed, v0:x = v0cosθt => 9100 = v0cos42°t => t = 9100 / (v0cos42°)Substitute this value of t in the formula for y:3400 = v0sin42°(9100 / (v0cos42°)) - (1/2)(9.8)(9100 / (v0cos42°))²We can simplify this equation as follows:tan42° = y/x => v0² = (x² + y²) / (2xytan42°)Substitute the values of x, y, and θ:v0² = [(9100)² + (3400)²] / [2(9100)(3400)tan42°]v0 = √(2gh), where g is the acceleration due to gravity and h is the height of fall of the bomb.v0 = √(2 × 9.8 × 3400) = 836 m/s

Therefore, the initial speed required is 836 m/s.(b) Time of flight:To calculate the time of flight, we can use the formula for x:x = v0cosθt => t = x / (v0cosθ)Substitute the values of x, v0, and θ:t = 9100 / (836 × cos42°) ≈ 14 sTherefore, the time of flight is 14 s.

The tracks of extratropical cyclones that form east of the rocky mountains typically move towards the great lakes region. This is true.

Extratropical cyclones that form east of the Rocky Mountains in North America tend to move towards the east and northeast, which often takes them towards the Great Lakes region.

This is due to the prevailing westerly winds at mid-latitudes, which steer these weather systems in that direction. However, the exact track of any given extratropical cyclone can be influenced by a variety of factors, including the strength and position of high and low pressure systems.

Yes, Olympus Mons, at 600 km across, is the largest volcano. It is situated on the planet Mars and is considered to be the largest volcano in our solar system. The height of this volcano from the base to the summit is 21 km which is about three times taller than Mount Everest. Scientists believe that it was formed as a result of hotspot volcanic activity beneath the planet's crust.

Olympus Mons is located on the Martian Tharsis bulge, a plateau that rises about 8 kilometers above the surrounding terrain. The volcano's base is about 600 km in diameter, and the caldera at the summit is 85 km wide. The mountain is shaped like a shield and is characterized by gently sloping sides.

Olympus Mons was discovered by humans in 1971, and since then, it has been studied extensively by scientists. It is estimated to be about 100 million years old, which makes it relatively young compared to some other volcanoes on Mars. The cause of its enormous size is the lack of plate tectonics on Mars. Unlike Earth, Mars does not have plates that move and recycle the crust, so the hotspots continue to build up on one another, resulting in a giant shield volcano.

In conclusion, Olympus Mons is the largest volcano known in the solar system, with a base about 600 km in diameter and a height of 21 km from the base to the summit. Its shield-like shape and lack of tectonic activity on Mars have allowed it to grow to this massive size.

Simple moving average is considered a time series forecasting technique.

A simple moving average is a method that calculates the average of a number of prices over a specific time frame, sometimes a specified number of days. A simple moving average (SMA) is formulated by computing the arithmetic mean of a given collection of data over a specific time period.

A simple moving average (SMA) is a moving average using arithmetic that is computed by averaging recent prices, adding that total, and then dividing that result by the number of computation periods. One may, for instance, add up a security's closing prices across a number of time periods and then divide the total by the same number of time periods. Long-term averages take longer to react to changes in the selling price of the securities themselves than do short-term averages.

Option A is the correct answer.

Explanation:

The sahel is a narrow band of semi-arid that forms a transition zone between the Sahara to the north and the savannas to the south. It is made up of flat, barren plains that stretch roughly 5,400 kilometers (3,300 miles) across Africa, from Senegal to Sudan.

The area of transition between the Sahara Desert and the grasslands of sub-Saharan Africa is known as the Sahel. The Sahel is a narrow band of land stretching approximately 3,360 miles from the Atlantic Ocean to the Red Sea.

The Sahel is characterized by a semi-arid climate and a mix of grasslands, savannas, and sparse forests. This is home to a diverse array of plant and animal species, including elephants, giraffes, and gazelles.

It is also home to many pastoral and nomadic communities that rely on livestock herding for their livelihoods. However, the region is facing numerous challenges, including drought, desertification, and conflict.

In recent years, the Sahel has become an area of increasing concern due to the growing threat of terrorism and violent extremism. Several countries in the region have experienced attacks by extremist groups such as Boko Haram and the Islamic State in West Africa.

The international community has been working to provide support and assistance to help address the complex challenges facing the Sahel.

In summary, the area of transition between the Sahara Desert and the grasslands of sub-Saharan Africa is known as the Sahel. The region is characterized by a semi-arid climate and a mix of grasslands, savannas, and sparse forests.

If it is currently winter and you're referring to the change in altitude of the noontime sun as summer approaches, it will generally increase. The altitude of the sun refers to its angle above the horizon at a particular location and time.

During winter, in many parts of the world, the Earth's axis is tilted away from the sun, causing the sun's rays to hit the Earth at a lower angle. This results in shorter days, lower temperatures, and a lower position of the sun in the sky at noon.

The sun's altitude is typically at its lowest point during the winter solstice, which is around December 21st in the Northern Hemisphere and around June 21st in the Southern Hemisphere.

As summer approaches, the Earth's axis gradually tilts toward the sun. This causes the sun's rays to strike the Earth at a higher angle, resulting in longer days, warmer temperatures, and an increasing position of the sun in the sky at noon.

The noon altitude of the sun is measured in degrees above the horizon at solar noon. December 21 is the winter solstice. At this time, the northern hemisphere is tilted away from the sun at its maximum angle, resulting in the shortest day and longest night of the year.

The highest noon altitude of the sun occurs in the tropics, while the lowest noon altitude of the sun occurs at higher latitudes. The altitude of the sun is the angle between the horizon and the center of the sun. The noon altitude of the sun varies depending on the observer's latitude and the time of year. On December 21st, the noon altitude of the sun is at its lowest in the northern hemisphere, while it is at its highest in the southern hemisphere. The latitude where the noon altitude of the sun is highest on December 21 is the Tropic of Capricorn, which is located at 23.5 degrees south. The latitude where the noon altitude of the sun is lowest on December 21 is the Arctic Circle, which is located at 66.5 degrees north.
