If a car is traveling at the speed of light and the car turns on the headlight, what would happen? Would the headlight not turn on at all, would the headlight travel at twice the speed of light, or would the headlight act like a flowing sink flowing out light?

Answer:

A

Explanation: edge

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.  

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km  

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)

v = 1463.4 Km/hr

The limit is the Chandrasekhar limit of 1.38 -> 1.4 solar masses. so once it reaches that limit it will become a neutron star so the answer is A

hope im right

At the time When the white dwarf with a mass of 1.4 solar masses so it is collapsed to create a neutron star. Hence, option A is correct.

It is the maximum mass of stabling the white dwarf star. The presently accepted value should be approx 1.4 M. Also, it should collapse via the electron degeneracy pressure and it resisted the collapse via the thermal pressure.

Also, when it should be reached the limit so it should develop a neutron star.

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!

Answer: 24 N

Explanation:

Given that the

Mass m = 4 kg

Coefficient of friction (μ) = 0.60

To calculate the static friction between the block and the table before any attempted motion, you will use the formula; F = (μ)N

Where

F = static friction

N = normal reaction = mg

g = acceleration due to gravity = 9.8 m/^2

Substitutes m, g and (μ) into the formula

F = 0.6 × 4 × 9.8

F = 23.52 N

Therefore, the static friction between the block and the table before any attempted motion is 24 N approximately.

The static friction between the block and the table before any attempted motion is to start equals 23.52 Newton.

Given the following data:

To determine the static friction between the block and the table before any attempted motion is to start:

Mathematically, the force of static friction is given by the formula;

\(F_s = uF_n\)   ...equation 1.

Where;

But, \(F_n = mg\)

\(F_s = umg\)   ...equation 2.

Substituting the given parameters into eqn. 2, we have;

\(F_s = 0.60 \times 4 \times 9.8\\\\F_s = 23.52\; Newton\)

Force of static friction = 23.52 Newton

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

Gravity is More Than a Name

The Apple, the Moon, and the Inverse Square Law

Newton's Law of Universal Gravitation

Cavendish and the Value of G

The Value of g

As discussed earlier in Lesson 3, Isaac Newton compared the acceleration of the moon to the acceleration of objects on earth. Believing that gravitational forces were responsible for each, Newton was able to draw an important conclusion about the dependence of gravity upon distance. This comparison led him to conclude that the force of gravitational attraction between the Earth and other objects is inversely proportional to the distance separating the earth's center from the object's center. But distance is not the only variable affecting the magnitude of a gravitational force. Consider Newton's famous equation

Fnet = m • a

Newton knew that the force that caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. So for Newton, the force of gravity acting between the earth and any other object is directly proportional to the mass of the earth, directly proportional to the mass of the object, and inversely proportional to the square of the distance that separates the centers of the earth and the object.
