What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

Justin and Oscar each hit a baseball with a bat. The baseballs have the same mass, but the ball Justin hits has a greater acceleration. What might be the reason for the greater acceleration of Justin's baseball?
Answers
The acceleration is different in both cases because, the force applied is different. Acceleration is force divided by mass of the object. Thus, Justin had greater force than Oscar.
What is force ?Force is an external agent acting on body to change its motion or deform it. There are various kinds of forces such as frictional force, gravitational force, nuclear force etc.
According to Newton's second law of motion, the force acting on an object is the product of its mass and acceleration.
Thus, F = ma
Hence, as the force increases the body is accelerated more.
With the same mass for the two balls, the force used to hit it was different and thus, the acceleration differs in both cases. Therefore, Justin has the greater force.

Foliation occurs when minerals are flattened by heat and pressure. this results in a layered or banded texture. What type of rock do you think is foliated?
Answers
Visible silicate minerals split into dark and light bands or lineations in a metamorphic foliation known as gneissic banding. Typically coarse and frequently folded, these grains. Gneiss is the name for a rock with this texture.
Some kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.)

A -0.00125 C charge is placed 3.62 m from a +0.00333 C charge. What is the magnitude of the electric force between them?
Remember, magnitudes are positive.
[?] N
Answers
Answer: 2858.7726N
Explanation:
Given that :
Charge 1 (q1) = -0.00125 C
Charge 2 (q2) = +0.00333 C
Distance (r) = 3.62 m
According to columb's Law: The magnitude of the force between any two charged objects :
Fe = (Kq1q2) / r^2
Coloumb's constant(k) = 9×10^9 Nm^2/C^2
Fe = (9×10^9 * 0.00125 * 0.00333) / 3.62^2
Fe = (0.0000374625 * 10^9) / 13.1044
Fe = 37462.5 / 13.1044
Fe = 2858.7726N

Mahiya and Mrinmoy are in a relay around a square field with each side of length 60m. First, Mahiya runs at a speed of 6 ms−1 for 60m to pass a baton to Mrinmoy. Then Mrinmoy runs 120m at 4ms−1 while Mahiya runs through the field to reach the other corner. Then Mrinmoy passes the baton. But Mahiya is now tired since she has been constantly running. So, she only runs at 3ms−1 for the final 60m. What is the average speed of the baton in ms−1?
Answers
The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\)
First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.
\(Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya\)Total Distance = 60 m + 120 m + 60 m = 240 m
Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:
\(Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s\)
Total Time = 60 s
Now, we finally find the average speed of the baton by using the formula:
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}\)
Average Speed = 4 ms⁻¹

How do we know there has not been an increase in the number of earthquakes? Officials from the U.S. Geological Survey, the government agency that keeps track of earthquakes, point to statistics. On average, there have been no more earthquakes so far in 2010 than there were in previous years.
What Happens During Earthquakes?
In reality, it's not the number of quakes that has gained our attention, but the devastating impact quakes can have. Earthquakes are very natural—it's inevitable that they'll happen because of the way the planet works. The earth's surface is made up of tectonic plates that fit together like puzzle pieces and are always moving past each other. When two of the plates' edges get caught, stress builds up at the fault line—the crack between the plates. When the plates are finally able to break free of each other, the stress is released, and an earthquake occurs. Earthquakes of varying strengths happen every day, usually at fault lines. Some of these quakes have a high magnitude, while others are relatively weak. But it's often where an earthquake takes place that determines whether it will be something that goes largely unnoticed, or a disaster that affects thousands of people.
What Is Changing?
In the past, earthquakes were not as much of a problem because Earth's population was smaller, and cities were less populated.
"Look at some of the big [earthquakes] recently," said Debarati Guha-Sapir of the World Health Organization. Guha-Sapir cited some earthquakes that took place in areas where the population had increased in recent years, making the quakes more serious. "Had the Izmit or Bhuj quakes [of 1999 and 2001] happened 30 years ago, the events would have been relatively insignificant, as the [populations] of these cities were a third of what [they were when the earthquakes happened]. Increasing population density makes a small event into a big one."
Some of the earthquakes that took place in early 2010 occurred in highly populated areas, as well. More people are moving into megacities that happen to be built on fault lines—and many cities are on fault lines. Of the 130 cities with more than one million people, more than half are in earthquake zones, making them more prone to earthquakes.
In many of these cities, officials have drawn up laws requiring that buildings be designed and constructed to endure earthquakes. But some cities, particularly those in developing countries, lack the resources to do this. There, people are rapidly putting up substandard buildings that can't withstand the force of the shaking earth. For example, the Haiti earthquake took place near the nation's crowded capital. There was a great deal of destruction because there were "too many people crammed into a city that wasn't meant to have that many people and have an earthquake," said University of Miami geologist Tim Dixon.
Another reason quakes seem worse is that we're paying more attention. Everyone noticed when the Haiti earthquake was quickly followed by the Chile earthquake. Many people watched the news and the Internet for updates on these disasters, unable to believe that they were seeing two major earthquakes in such a short period of time. But eventually, the earth will have a period when earthquakes are minor or in unpopulated areas. Then people won't notice quite so much anymore.
"People are paying attention to the violent planet we've always lived in," said Dennis Mileti, a seismic researcher. "Come back [at a time when] there have been no [noticeable] earthquakes, [and] most people will have forgotten [about them] again."
According to the article, what is one reason why it seems as if the world is experiencing more earthquakes than usual?

V= 1.4^3
V=2.744cm^3 or 2744mm^3
(It looks 1.4 to me tho)
The magnitude of the metric volume of the cube is 2.744 cubic centimeter.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Finding an object's volume can help us calculate the quantity needed to fill it, such as the volume of water needed to fill a bottle, aquarium, or water tank.
According to the picture:
Length of each sides of the cube is: a = 1.4 cm.
We have to fine: volume of the metric cube: V =?
We know that: volume of a cube is given by:
V = a³
