As the car goes through the valley in part A the car's speed is 15 m/s, its mass is 20 kg and the radius of valley (r) is 5 meters, determine the magnitude of the centripetal force acting on the car. *

Answers

Answer 1

Answer:

Centripetal force, F = 900 N

Explanation:

We have,

Speed of a car is 15 m/s

Mass of the car is 20 kg

Radius of the valley is 5 m

It is required to find the magnitude of the centripetal force acting on the car. The centripetal force acting on the car is due to the motion in circular path. The centripetal force is given by :

\(F=\dfrac{mv^2}{r}\\\\F=\dfrac{20\times (15)^2}{5}\\\\F=900\ N\)

So, the centripetal force of 900 N is acting on the car.

Scientific discovery has helped create new technology which is pretty evident from the different technological products we are using in our day-to-day life such as mobile phones, computers, nuclear power plants, and other technological advancements.

What is science?

Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.

A method of learning about the world is science. Science allows people to participate in the creation of new knowledge as well as use that knowledge to further their goals. It is both a process, a product, and an institution.

The various technical items we use in our daily lives, such as mobile phones, computers, nuclear power plants, and other technological breakthroughs, are very strong evidence that scientific research has contributed to the creation of new technology.

Thus, by the above-mentioned example, we can say that scientific discovery has helped create new technology.

Discuss one component of your school's recycling system that could be automated and predict the economic impact.

Answers

One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.

Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.

The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.

Answer:

Our school has color coded virtual trash cans. For example, a trash can for only paper will only accept paper items, if the item put inside is not paper, it will litter it out and all students have cleaning duties throughout the week so even if you or someone litters you’ll probably have to clean it up at some point anyways.

What is potential energy ?

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

List three evidences that show that the Bible is the Word of God.

Answers

Answer:1.God tells us that He is the Author  (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))

1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)

3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.

Explanation:

Answer:

Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.

The Word of God: Evidence that Scripture is Divine

First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.

Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

Answers

Answer:

c

Explanation:

The step that has been missing in the carbon cycle has been decomposition, as it breaks the organic matter into simpler carbon that can be absorbed. Thus the correct option is C.

The carbon cycle can be defined as the transfer of carbon in varying forms in the atmosphere. Carbon has been present in the atmosphere in the form of air.

The air has been taken up by the plants for the formation of glucose. The atmospheric carbon has been converted into sugars by photosynthesis.

The sugar has been taken up by the consumers and is released back into the earth from the decomposition of the plants and waste from consumers or by the combustion process.

The carbon cycle can be given as:

Photosynthesis (Food) \(\rightarrow\) Consumers

    Decomposition \(\downarrow\)               \(\downarrow\) Combustion

                            Carbon dioxide

The step that has been missing in the carbon cycle has been decomposition, as it breaks the organic matter into simpler carbon that can be absorbed. Thus the correct option is C.

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline

Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what

Answers

Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)

Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.


The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.
