C) photosynthesis

During the process of photosynthesis, trees absorb carbon dioxide from the air.

The point of origin is the three dimensional location while the point of convergence is the area containing intersections.

Blood pattern analysis is usually used by the forensic specialists to determine the facts surrounding an investigation using physical nature of blood stains.

There are different types of blood analysis but the one that was displayed in the picture is the impact spatter patterns which contains a point of origin and point of convergence.

The point of origin is the three-dimensional location from which blood spatter originated while the point of convergence is the area containing the intersections generated by lines drawn through the long axes of individual stains that indicates in two dimensions the location of the blood source.

it would deform, transferring some of its kinetic energy into the concrete molecules. Depending on the relative mass and anchorage of the wall, this may cause it to shift.

The pressure on the top face of the block is 14,000 N/m².

The pressure experienced by an object is force per unit area of the surface. The pressure experienced  by the object increases with increase in the applied force and decrease in surface area.

The pressure on the top face of the block is calculated as follows;

P = F/A

where;

P = (3.5 x 10³)/(0.25)

P = 14,000 N/m²

Thus, the pressure on the top face of the block is 14,000 N/m².

Given :-

To Find :-

Solution :-

As per the provided information in the given question, we have been given that Force is 10000 Newton , Area is given 200 meter² . And, we have been asked to calculate the Pressure exerted on the Ground .

For calculating the Pressure , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Pressure = Force / Area

⇒ Pressure = 10000 / 200

⇒ Pressure = 50

Hence :-

Answer:

50 Pa

Explanation:

Here,

→Force(F)=10000N

→Area(A)=200m²

As we have,

→Pressure=Force/Area

→Pressure=10000N/200m²

→Pressure=50 Pa

The statement is true. Binaural fusion is the process in which the brain processes information from each ear and creates two different perceptions of the location of the sound.

Binaural fusion, also known as binaural integration, is a cognitive process in which different auditory information is delivered binaurally, or to each ear separately.

This mechanism is critical in human speech comprehension because one ear may take up more information about speech stimuli than the other.

Yes, the brain processes the information from both ears, but it only uses the tiny difference among them to produce one sense of where a sound is coming from.

Hence the statement is true.

A black hole cannot eat an entire galaxy.

Some scientists believe that stuff that goes into a black hole might go into another dimension but no one has been able to prove that theory, so most believe that any matter that enters a black hole is torn apart into the smallest components possible and eventually squeezed into a singularity

We are given that:

We need to find:

Using equations of motion:

➙ v² - u² = 2as

➙ v = u + at

here,

From the given information, we can conclude that:

Now, using equation of motion:

➝ v = u + at

➝ v = 0 + ( 8 × 1.5 )

➝ v = 0 + 12 .0

➝ v = 12 m/s

For, acceleration :

➝ v² - u² = 2as

➝ ( 12 )² - ( 0 )² = 2 × 8 × s

➝ 144 - 0 = 16s

➝ 16 s = 144

➝ s = 144 / 16

➝ s = 9m

Answer :

The earth wire is a safety device that is attached to the appliance's casing. If the live wire falls loose and hits the casing, the earth wire offers a conduit for the electrical current to pass. The high current flowing through the ground line melts the fuse, turning off the device. If there is no earth wire, we will be the least resistance path for the current to ground in the event of a fault (shock), as there is no other way for the fault current to dissipate. In the event that there is an earth wire. Because the earth line is the least resistance path to the ground, we will be unaffected.

Answer:

54 N

Explanation:

a= v/t

3÷5/3= 1.8 m/s^2

f=ma

1.8 x 60 = 108/2 = 54 N

The work done against the braking force is the change in the kinetic energy of the skater is 54 N.

Work is said to be done whenever a force moves an object over a distance.

[tex]W = F = ma[/tex]

where

Acceleration is given by

Explanation:

Contrary to answers a, b, and c, volcanic rocks, like basalt, andesite, and rhyolite, are fine-grained which are extrusive igneous rocks.

Intrusive rocks, also called plutonic rock, are coarse-grained and cool slowly without ever reaching the surface. While intrusive igneous rocks do solidify in the earth they do eventually become exposed by erosion.

One step of copper mining requires blasting ore to be able to blasted and extracted from mine.

Mercury is used to recover minute pieces of gold that is mixed in soil and sediment. Sometimes Mercury can be lost in this process resulting in widespread contamination of local rivers and lakes.

Hundreds of tons of rock are unearthed, moved and crushed in mining operation significantly increasing the amount of dust and particulates in the air.

Strip mining (also known as mountaintop removal) involves scraping away earth and rocks to get to coal buried near the surface. This often results in the destruction of ecosystems.
