Answer:

48.26 m

Explanation:

time to goes up (till stop for a while in the air - maximum height)

vt = vo + a t

0 = 15 + g . t

0 = 15 + (-9.8) . t

9.8t = 15

t = 1.531 s

so the time left to goes down is

4.0 - 1.531 = 2.469 s

height from the top of building can find it by using

vo =√(2gh)

15 = √(2)(9.8).h

15² = 19.6h

h = 225/19.6 = 11.48 m

so the distance of maximum height to the ground is

t = √(2H/g)

2.469 = √(2H/9.8)

2.469² = 2H/9.8

6.096 = 2H/9.8

2H = 6.096 x 9.8 = 59.74 m

so the vertical distance of the building (or the building height's is)

H - h = 59.74 - 11.48 = 48.26 m

Take into account that the acceleration of the car can be calculated by using the following expression:

where,

vo: initial speed = 0m/s

v: final speed = 18.4m/s

t: time = 27.8s

Replace the previous values of the parameters into the formula for a and simplify:

Hence, the acceleration of the car is approximately 0.66m/s^2

Plate Tectonic Setting: Subduction Zones (Convergent Margins)

3. Shield Volcano:

Plate Tectonic Setting: Mostly Mantle Plumes, some Spreading Ridges

4. Large Igneous Provinces (LIPs):

Plate Tectonic Setting: Various tectonic settings

Volcano types can be associated with specific plate tectonic settings and magma compositions. Let's match the volcano types with their correct plate tectonic settings and magma compositions:

1. Cinder Cone:

Plate Tectonic Setting: Mostly Spreading Ridges, some Mantle Plumes

Magma Composition: Mafic

Cinder cones are typically small, steep-sided volcanoes that form from the eruption of basaltic magma. They are commonly found in volcanic regions associated with spreading ridges, where tectonic plates are moving apart, or in areas influenced by mantle plumes, such as hotspot volcanism.

2. Composite/Stratovolcano:

Plate Tectonic Setting: Subduction Zones (Convergent Margins)

Magma Composition: Intermediate, varies from felsic to mafic

Composite or stratovolcanoes are characterized by their steep slopes and alternating layers of lava flows and pyroclastic materials. They are commonly found in subduction zones, where an oceanic plate is being subducted beneath  continental plate. The magma composition of these volcanoes varies, ranging from felsic (high silica content) to mafic (lower silica content).

3. Shield Volcano:

Plate Tectonic Setting: Mostly Mantle Plumes, some Spreading Ridges

Magma Composition: Mafic

Shield volcanoes are large, broad, and gently sloping volcanoes that form from the eruption of basaltic magma. They are often associated with mantle plumes, such as those found in hotspot regions, as well as in volcanic areas influenced by spreading ridges.

4. Large Igneous Provinces (LIPs):

Plate Tectonic Setting: Various tectonic settings

Magma Composition: Mafic

Large Igneous Provinces (LIPs) are extensive regions of volcanic and intrusive rock formations that are associated with massive outpourings of mafic magma. They can occur in various tectonic settings, including continental rifts, hotspot regions, and flood basalt provinces.

5. Seafloor Volcanism, Pillow Lava:

Plate Tectonic Setting: Mostly Spreading Ridges

Magma Composition: Mafic

Seafloor volcanism is primarily associated with spreading ridges, where magma wells up and creates new oceanic crust. The lava erupted underwater cools rapidly, forming pillow-shaped structures known as pillow lavas. The magma composition is typically mafic, dominated by basaltic lavas.

On Mercury and the Moon, we notice that larger craters overlie smaller craters. This phenomenon occurs because larger impacts create more extensive shockwaves and debris

This observation can be attributed to the geological process known as "crater saturation." Over time, the surfaces of Mercury and the Moon have experienced numerous impacts from meteoroids and other celestial bodies. As a result, smaller craters formed earlier in their history. However, subsequent impacts from larger objects have overlaid these smaller craters, effectively "erasing" them from the surface. This phenomenon occurs because larger impacts create more extensive shockwaves and debris, which can bury or obliterate pre-existing smaller craters. By studying the distribution and characteristics of these overlapping craters, scientists can gain insights into the history and evolution of these planetary bodies.

Answer:

A. Applied force

B. Normal force

C. Frictional force

D. Gravitational force

Explanation of the forces with examples shown in the diagram:

A. Applied force:- A pushing or pulling force used to move an object. A person or any other object in this situation applies a force to an object. A chair being moved to the opposite side of the room, as an example.

B. Normal force:- This force is applied to a moving object when it comes into contact with a steady object. A normal force is typically applied horizontally between two objects that are in touch. An illustration would be a book on a table or a person leaning against a wall.

C. Frictional force:- Friction is created as an object moves across a surface. Slider or static forces can cause friction. The characteristics of the two interacting surfaces determine friction. A ball rolling on the floor is one example, as is a book sliding over the table.

D. Gravitational force:- This is the force that causes the Earth, the moon, and other extraordinarily large objects to pull other objects toward them. Every object on Earth is subject to gravity, which pulls objects downward and toward the planet's centre.

The object believed to lie at the center of the Milky Way galaxy is a **supermassive black hole**.

Extensive observational evidence, including the motion of stars and gas clouds in the galactic center, indicates the presence of a massive and compact object. This object, known as Sagittarius A* (Sgr A*), has a mass of approximately four million times that of our Sun. It is located within a region called the Galactic Center, which is obscured by dust and gas, making direct observations challenging in visible light. However, observations using other wavelengths, such as radio and X-rays, have provided compelling evidence for the presence of a supermassive black hole. The behavior of stars in close proximity to Sgr A*, as well as the energetic processes observed in its vicinity, strongly suggest that it is a black hole with an incredibly strong gravitational pull at the center of our galaxy.

X-rays are a form of electromagnetic radiation that have higher energy than visible light. As a result, X-rays travel through space at a faster speed than visible light.  True.

This is because X-rays have a shorter wavelength and higher frequency than visible light, which gives them more energy.

The speed of light in a vacuum is a fundamental constant of nature and is the same for all forms of electromagnetic radiation, including X-rays. However, X-rays can travel faster through materials that are denser than air, such as metal or dense materials, because they can penetrate these materials more easily.

Therefore, X-rays travel through space faster than visible light due to their higher energy and shorter wavelength, but they may travel more slowly through certain materials in the presence of a medium.

When two resistors are connected in series, their equivalent resistance is 260.5 Ω. However, when the same resistors are connected in parallel, the equivalent resistance is 25.5 Ω.

When resistors are connected in series, their resistances add up to give the total equivalent resistance. In this case, the two resistors in series have a combined resistance of 260.5 Ω. On the other hand, when resistors are connected in parallel, their reciprocals are summed to determine the equivalent resistance. The reciprocal of the equivalent resistance is equal to the sum of the reciprocals of the individual resistances. By taking the reciprocal of 25.5 Ω, we can determine the combined resistance of the two parallel resistors. The difference in the equivalent resistances when connected in series versus parallel is due to the different formulas used to calculate the total resistance in each configuration
