Answer:

Two of Einstein’s influential ideas introduced in 1905 were the theory of special relativity and the concept of a light quantum, which we now call a photon. Beyond 1905, Einstein went further to suggest that freely propagating electromagnetic waves consisted of photons that are particles of light in the same sense that electrons or other massive particles are particles of matter. A beam of monochromatic light of wavelength \lambda (or equivalently, of frequency f) can be seen either as a classical wave or as a collection of photons that travel in a vacuum with one speed, c (the speed of light), and all carrying the same energy, {E}_{f}=hf. This idea proved useful for explaining the interactions of light with particles of matter.

Explanation:

The three results are precise. This is because they are all within 0.3 g of one another. However, the results are not accurate, because they are all about 5 g away from the correct value for the mass of the apple.

Please mark as Brainliest

Considering the definition of accuracy and precision, the measurements are precise but not accurate.

Accuracy is the closeness of a measurement to the true value, while precision is the degree of closeness of the values ​​of several measurements at a point.

In other words, precision is the consistency of the results when multiple measurements are repeated. That is, it refers to the degree of proximity or closeness of the results of different measurements to each other. That is, precision refers to how close the measurements are to each other.

Accuracy indicates the degree of closeness or proximity between a measured value, or a series of observed values, with the real value of something. That is, the accuracy is the degree of agreement between the result of the measurements and the true value. In other words, accuracy refers to how close a measurement system's measurements are to the true value.

Accuracy and precision are independent of each other. Thus, the results in the values ​​of a measurement can be precise and not exact (and vice versa).

In this case, the average of the 3 measurements of the mass of the apple is:

(167+166.9+167.2)÷3 = 167.03 g

So, the repeated measurements are close to each other with a range of 0.3. Then,  this closeness means that the measurements are precise.

On the other side, the difference between the mean measurement and the true mass of the apple is:

172 - 167.03 = 4.97 g

This indicates that the repeated measurements are far from the true mass of the apple with a difference of 4.97 g. This means that the measurements are not accurate.  

In summary, the measurements are precise but not accurate.

Answer  the gerater mass and the faster the object moves the more kenetic enegry there would be

Explanation:

Answer:

The greater the mass and acceleration the more kinetic energy there will be.

Kinetic energy and Explanation

The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Mass and Explanation

Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.

Acceleration and Explanation

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

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

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.

Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,

Using Formula:

K.E=\(1/2mv^{2}\)

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.125)(4)^{2}\)

K.E=\(1/2(0.125)(16)\)

K.E=1/2(2)

K.E=1

When the mass of the bottle is 0.250 kg, the Kinetic Energy  is

K.E=\(1/2(0.250)(4)^{2}\)

K.E=1/2(0.125)(16)

K.E=1/2(4)

K.E=2

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.375)(4)^{2}\)

K.E=1/2(0.375)(16)

K.E=1/2(6)

K.E=3

When the mass of the bottle is 0.500 kg, the Kinetic Energy  is

K.E=\(1/2(0.500)(4)^{2}\)

K.E=1/2(0.500)(16)

K.E=1/2(8)

K.E=4

Now we can calculate the change in kinetic energy (ΔKE):

ΔKE = KE(final) - KE(initial)

= 4 kg m*2/s*2 - 1 kg m*2/s*2

= 3 kg m*2/s*2

https://brainly.com/question/8101588

Answer:

Explanation:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object

which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

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!
