Geography

natulia [17]3 years ago
3 0

The correct answer is D. Both compare the object to an event in history.

Explanation

Relative dating is a method of dating and classifying the age or presence between two or more items. This method is based on three principles, that of superposition, continuity, and paleontological identity. On the other hand, radioactive dating is another dating method that uses the principle of decay of radioactive isotopes to know the age of one element concerning another. These two methods are generally used in paleontology, geology, and other sciences that study the antiquity of different objects, materials, or elements and need to date broad time spectra. Therefore, the correct answer is D. Both compare the object to an event in history.

Vladimir [108]

:

35 minutes (See proof below)

Explanation:

Given

Velocity = v = 0.99c

Time = ∆t =5 minutes

Lorentz Factor is the factor by which time, length, and relativistic mass change for an object while that object is moving and it is given as

y = 1/√(1 - v²/c²) where v = velocity = 0.99c and c = time constant = 1

So,

y = 1/√(1 - (0.99c)²/c²)

y = 1/√(1 - 0.9801c²/c²)

y = 1/√(1 - 0.9801)

y = 1/√0.0199

y = 7.088812050083359

Calculating her catnap;

Catnap Time = ∆t * y

= 5 minutes * 7.088812050083359

= 35.44406025041679 minutes

= 35 minutes ----- Approximated

r-ruslan [8.4K]

Answer:

contributes as to why pyramids were built with great distinction and effort.

Explanation:

As the central idea of the article is about the purpose and distinction of the pyramids, the concept of ka contributes as to why pyramids were built with great distinction and effort.

It helps the readers to understand that pharaohs' wealth and richness could be enjoyed in the afterlife by thier kas. So building a great pyramid for the pharaohs was an important tradition for the Egyptians.

Ka is believed to be a second self of an individual. It is the spirit/energy of a person that transcends into the afterlife after death.
