Three resistors, of 100, 200, and 300 ohms are connected in parallel. What is their equivalent resistance?
(Unit = ohms)
Answers
Answer:
Equivalent resistanfe in parallel (R):
1/R = 1/100 + 1/200 + 1/300
1/R = (6 + 3 + 2)/600
1/R = 11/600
R = 600/11 = 54.55 ohms
Equivalent resistance is 54.55Ω.
It is given that three resistors are,
\(R_{1}\) = 100Ω, \(R_{2}\) = 200Ω, and \(R_{3}\) =300Ω
It is required to find the equivalent resistance when resistors connected in parallel.
What is the equivalent resistance?
As we know, when the resistors are connected in parallel,
\(\frac{1}{R} =\frac{1}{R_{1} } +\frac{1}{R_{2} }+\frac{1}{R_{3} }\)
Putting the values, we have
\(\frac{1}{R} =\frac{1}{100} } +\frac{1}{200 }+\frac{1}{300 }\)
\(\frac{1}{R} =\frac{(6+3+2)}{600}\)
\(\frac{1}{R} =\frac{11}{600}\)
\(R=\frac{600}{11}\)
R=54.55Ω
Thus, equivalent resistance or total resistance when resistance are connected in parallel is 54.55Ω.

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!

Write a report on waves. Some questions you might consider are: What makes a wave? Why are some waves small and some large? How are waves classified? Are there different kinds of waves? What happens when a wave meets the shore? Where in the world do you find the best waves for surfing?
Answers
Answer:
The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates. Portugal is one of the best places to surf because they have waves that can reach up to 6 to 15 feet high!

You probably use the term heat many times a day. As an example, when you cook, dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Why is heat the correct term to use in these examples?
A. They show that when objects are touching, they are the same temperature.
B. They show that heat flows from something warmer to something cooler.
C. They indicate that heat is created to raise the temperature of something.
D. They indicate that the kinetic energy of the particles decreases when something is heated.
Answers
Answer: Pretty sure it is B
Explanation:
When you cook, dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Heat is the correct term to use in these cases because they show that heat flows from something warmer to something cooler. So, option(B) is correct.
What is heat?As a result of a temperature difference, energy is transferred from one body to another and is known as heat. The hotter body transfers energy—heat flows—from the cooler body when two bodies with different temperatures are brought together.
An increase in the temperature of the colder body and a reduction in the temperature of the hotter body are typically, though not always, the results of this energy transfer.
A substance can absorb heat without increasing in temperature by transitioning from one physical state (or phase) to another, such as melting, sublimation, boiling, or shifting from one solid form to another (usually called a crystalline transition).

Americium-241 isotope would be expected to have the longest half-life. Hence, option (D) is correct.
What is half-life?
In radioactivity, the half-life is the time required for one-half of a radioactive sample's atomic nuclei to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time required for the number of disintegrations per second of a radioactive material to decrease by one-half.
According to given data:
Rate of decay is the highest for Mercury-194, hence, its half-life is least. Then rate of decay is lowest for Americium-241, hence, its half-life is the longest. Hence, option (D) is correct.
The order of half-life according to the data is:
Americium-241 > Silver-108 > Californium-249 > Mercury-194.

The sun revolve about a point in the centre of our galaxy taking the entire solar system with it at a speed of 220 km/s. When the sun rises in the morning on December 20th and then rises again December 20th of the next year, Earth is said to have revolved around the sun one time. The correct option is A.
What is revolution?The movement of the earth around the sun in a particular path is defined as the revolution. The earth revolves from west to east which is in the anticlockwise direction. The revolution speed of the earth is 30 km/s⁻¹.
The one revolution of the earth around the sun takes around one year or precisely 365.242 days. Revolution has a direct influence on the varied length of day and night time. The duration of days and nights are same at the equator.
The earth moves slowly so how can it go around the sun in 1 day or 2 times a day or 2 times a year.
