Hello!

Tara goes on a camel safari in africa. she travels 5 km north, then 3km east and then 1km north again. What distance did she cover ? What was her displacement ?​

We have the following data:  

Analyzing the statement, we have a rectangle triangle (ABC), we apply the data to the formula of the theorem of pythagoras, we have:

Tara covers a distance of 9 km (5 km + 3 km + 1 km) and the displacement (AB) is approximately 6.7 km

If we check A. , Americium 242, it has low penetration of alpha radiation and it was obvious that it was radioactive as the sign says. I said it was radioactive because it was made from bombarding uranium-238 with alpha particles (helium nuclei). An alpha particle was made from two protons and two neutrons. Proton and neutrons are both have strong interactions.

If we check B. , Mg-24 or Magnesium 24, it was only use to study heart disease. Magnesium helps us to maintain normal nerves and muscle functions, supports a healthy immune system, keeps the heartbeat steady, help bones remain same, regulate blood glucose levels, and aid in the production of energy and air. So it was not RADIOACTIVE, since it was useful.

If we check C. and D. , Plutonium-241 captures a neutron and Uranium-238 can be converted into plutonium-239. To produce plutonium-239, atoms of uranium-238 are exploded to neutrons. So I say, these two are RADIOACTIVE.

FINAL ANSWER: B. MG-24 OR Magnesium-24

he was the one who proposed the plum pudding model and he was also the one who discovered the one of the subatomic particle which is the electron.

Hello!

Suppose that an 8.0 L tank contain oxygen at a pressure of 44 atm. What pressure does this amount of oxygen exert in a 55.0 L tank at the same temperature ?

We have the following data:

V1 (final volume) = 8.0 L

P1 (initial pressure) = 44 atm

P2 (final pressure) = ? (in atm)

V2 (final volume) = 55.0 L

We have an isothermal transformation, its temperature remains constant, the volume and pressure of the gas are inversely proportional, that is, the volume of the gas in the container increases, then decreases its volume. Applying the data to the formula of Boyle's Law, we have:
