The cloth shroud from around a mummy is found to have a 14C activity of 8.4 disintegrations per minute per gram of carbon as com
kondaur [170]

Answer:

48889 years

Explanation:

Activity of the living sample Ao= 15.2 disintegration per minute

Activity of the cloth A= 8.4 disintegration per minute

Half life of 14C= 5715 years

Time taken for the decay t= the unknown

From;

0.693/5715 = 2.303/t log (15.2/8.4)

1.213 × 10^-4 = 2.303/t log (1.8095)

1.213 × 10^-4 = 0.593/t

t= 0.593/1.213 × 10^-4

t= 4888.7 years

t= 48889 years

How does the energy of the atoms in a hot cup of coffee compare to the energy of the atoms in a piece of ice?
Nonamiya [84]

Answer:

The atoms in the cup of coffee have more energy.

Explanation:

The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.

The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.

Since the hot cup of coffee has  a higher temperature, it means it also have the highest amount of energy. The correct option is;

The atoms in the cup of coffee have more energy.

What evidence did Copernicus use to explain that the sun is at the<br> center of the solar system?
Ahat [919]

Answer:

Copernicus's model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds. In a book called On the Revolutions of the Heavenly Bodies, Copernicus proposed that the Sun, not the Earth, was the center of the Solar System. Such a model is called a heliocentric system.
