Scientific model of volcanic eruptions using computer programming is very helpful to identify their origin and consequences. The biggest benefit of these model is to identify the physical behaviors of magma .
What are scientific models ?Scientific model are used to visualize the complex theories and concepts. There are both theoretical models and visual models. Nowadays complex problems and processes are easily solving using well designed computer programmes and simulations.
By creating a sophisticated computer model based on the most recent physical understanding of magma behavior, its most likely path of least resistance, and statistical information obtained from prior volcanic eruptions, scientists was able to address these issues.
They were able to predict the site of historical events that were not used to fine-tune the model by using historical data collected from Campi Flegrei, a caldera close to Naples, Italy etc.

What trend does the reactivity of nonmetals show in a periodic table? a) random changes without any trends on the periodic table b) changes according to trends on the periodic table c) increases from left to right across the periodic table d) decreases from left to right across the periodic table
Answer:
The answer is C. increases from left to right across the periodic table
Explanation:
I took the test
The reactivity increases as we move from left to right in the nonmetals sector of the periodic table. For instance, phosphorus is less reactive than chlorine. The reactivity does, however, diminish as we descend a column of nonmetals.
What reactivity of nonmetals show in a periodic table?Across a period, responsiveness declines as you move from left to right. Higher reactivity results from simpler electron transfer or removal as you move further to the left and down the periodic chart.
The reactivity of non-metals decreases as we move down a group. This is due to: An increase in the quantity of valence shells. The nucleus can no longer hold the electrons with the same force.
Therefore, In a period, the reactivity of non-metals rises from left to right; however, as we move down a group, the reactivity falls down because the tendency to take electrons declines.

You run from your house to a friend's house that is 3 miles away in 30 minutes. You then
immediately walk home, taking 1 hour on your return trip.
Your House
Friend's House
West East
v=d/t
--
v=6mi = 7
-3 miles
a. What was the average speed (in mi/hr) for the entire trip? ,07
b. What was the average velocity (in mi/hr) for the entire trip?
Answer:
a. The average speed is 4 mi/hr
b. The average velocity is 0 mi/hr
Explanation:
a. The average speed is given by the following formula;
[tex]Average \ speed = \dfrac{Total \ Distance}{Total \ Time}[/tex]
The given information are;
The time it took for one friend to run to his friend's house = 30 minutes
The distance between the two houses = 3 miles
The time it took for the friend to walk home = 1 hour
Therefore, the distance the friend ran going to his friend's house = 3 miles and the distance the friend walked going back his house = 3 miles
The total distance travelled = 3 + 3 = 6 miles
The total time taken = 1 hour + 30 minutes = 1 hour 30 minutes = 1.5 hours
Therefore;
[tex]The \ average \ speed = \dfrac{Total \ Distance}{Total \ Time} = \dfrac{6 \ miles }{1.5 \ Hours} = 4 \ miles \ per \ hour[/tex]
The average speed for the entire trip = 4 mi/hr
b. The average velocity is the total change in position divided by the total time taken to make the change or total displacement divided by the total time for the displacement
Mathematically, average velocity is given as follows;
[tex]The \ average \ velocity = \dfrac{Final \ location - Initial \ location}{Time \ taken \ for \ the \ change \ in \ location}[/tex]
[tex]The \ average \ velocity = \dfrac{Total \ displacement}{Time \ taken \ for \ the \ change \ in \ location}[/tex]
[tex]The \ average \ velocity = \dfrac{Total \ change \ in \ location}{Time \ taken \ for \ the \ change \ in \ location}[/tex]
Given that the friend changed his location to his friend's house, a distance of 3 miles he we have;
Initial change in location of the friend = 3 miles
After which the friend then relocates back to his house (and we know that it is the same journey but in opposite direction, he we have;
Final change in location of the friend = -3 miles
We are given that he ran to his friend's house and walked back home in a total time of 1 hour + 30 minutes = 1.5 hours, therefore, we have;
[tex]The \ average \ velocity = \dfrac{Sum \ total \ of \ change \ in \ location}{Time \ taken \ for \ the \ change \ in \ location} = \dfrac{3 + (-3) }{1.5}[/tex]
[tex]The \ average \ velocity = \dfrac{3 \ miles + (-3) \ miles }{1.5} = \dfrac{0 \ miles }{1.5} = 0 \ mi/hr[/tex]
The average velocity = 0 mi/hr.

An egg is dropped from a building that is 61 m high. What is the velocity when it hits the ground and how long did it take?
Answer:
the velocity is 10.6m/s
the time taken is 1.5sec
Explanation:
height (h)=61m
from,
[tex] {v}^{2} = 2gh[/tex]
v^2 = 2 (10)(61)
v^2 = 1220
v^2 = 10.6m/s
for time
[tex]v = \frac{1}{2} g {t}^{2} [/tex]
v=10.6
10.6=1×10t^2/2
10.6=5t^2
10.6/5=5t^2/5

The rotation is a circulatory motion of an object around the axis and maybe for infinite time and pass internally by the body's own center of mass then the body is said to be spinning.
Revolution is used synonym for rotation. Such as planet earth rotates around the sun on its axis. Another example of this motion can be that of dreidel spinning on its pointed edge.Hence option C is correct.

Why do you think false sciences are so widespread?
Answer:
The Internet (social media to be precise)
Explanation:
False science are purported scientific conclusions drawn without any scientific data or procedures followed to arrive at such conclusions. These purported conclusions would have been irrelevant or not widespread without the internet or social media but the easy accessibility to social media globally has made "everyone" to be a scientist or even a publisher without scientific steps.
Some innocent individuals also help share (on the internet) these false science because of the inability to differentiate between the real scientific process and the ones done without any/some due scientific processes hence assisting in promoting these false science unknowingly. If there were no internet, these false sciences would not be this widespread as information will not travel this fast.

A water-balloon launcher with a mass of 1.75 kg is suspended on a wire. It fires a 1.25 kg balloon to the east at a velocity of 12.0 m/s. What is the resulting velocity of the launcher if the net force on the launcher is equal to the reaction force? O A. 6.1 m/s east B. 16.8 m/s west C. 7.6 m/s west D. 8.6 m/s west
Answer:
8.6 to west
Explanation:
The initial momentum of the system is given by the sum of the momentum of the launcher and the momentum of the balloon. The correct answer is option C. 7.6 m/s west.
To solve this problem, we can apply the principle of conservation of momentum. According to this principle, the total momentum before an event is equal to the total momentum after the event, assuming no external forces act on the system.
The momentum of an object is calculated by multiplying its mass by its velocity.
Initial momentum = (mass of launcher × velocity of launcher) + (mass of balloon × velocity of balloon)
Let's substitute the given values into the equation:
Initial momentum:
[tex](1.75 kg * 0 m/s) + (1.25 kg * 12.0 m/s)[/tex]
Initial momentum = 15 kg·m/s
Since the net force on the launcher is equal to the reaction force, we can assume no external forces act on the system. Therefore, the total momentum before firing the balloon is equal to the total momentum after firing the balloon.
Final momentum = (mass of launcher + mass of balloon) × final velocity of the launcher
Let's solve for the final velocity of the launcher:
Final momentum:
[tex](1.75 kg + 1.25 kg)[/tex] × Final velocity of the launcher
15 kg·m/s = 3 kg × final velocity of the launcher
Dividing both sides of the equation by 3 kg gives us:
The final velocity of the launcher = 15 kg·m/s / 3 kg
The final velocity of the launcher = 5 m/s
Since the initial velocity of the balloon is to the east, the final velocity of the launcher will be to the west. Therefore, the correct answer is option C. 7.6 m/s west.
