Hey so i am taking the test and my sources say that the answer is A.) A boy running at a constant speed across the street. This is because the boy is moving at a rate that is growing while he runs. This is also known as velocity.

The half life of radium-226 is 1600 years. If you have 200 grams of radium today how many grams would be present in 8000 years?
Sveta_85 [38]

Answer:

Half life is the time taken by a radio active isotope to reduce by half of its original amount. Radium-226 has a half life of 1602 years meaning that it would take 1602 years for a mass of radium to reduce by half.

Number of half lives in 9612 years = 9612/1602 = 6 half lives

New mass = Original mass x (1/2)n where n is the number of half lives.

Therefore, New mass= 500 x (1/2)∧6

                                 = 500 x 0.015625

                                 = 7.8125 g

Hence the mass of radium after 9612 years will be 7.8125 grams.

Which mineral(s) might you be examining if you place some hydrochloric (hcl) acid on a sample and it fizzes?
makvit [3.9K]
The minerals that one might be examining if you place some hydrochloric acid on a sample and it fizzes are Calcite and Dolomite.
Calcite and dolomite are very similar minerals. Both have the same hardness, the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test; A drop of 1 M HCl on calcite produces an instant , obvious Fizz; a drop on dolomite produces slow or no obvious bubbling.
