## Physics Quiz Answers

1. Mercury was used for aviation in ancient times. NASA also uses mercury for the same purposes. Check here for more

2. CERN has the statue of Shiva in its premises. Know the reason here in one of our previous articles WHY DOES CERN HAVE A STATUE OF LORD SHIVA

3. Entroy is either increasing or constant. So, its time derivative is either positive or zero.

4. Total probablity is always equal to one. Wherever your brother is inside the room, he is inside the room anyway. Hence, we shall count it as total probability.

5. Wave function is a complex number. So, it doesn’t have any physical significance. Quantum Mechanics and Double Slit Experiment

6. Check previous article for the explanation Mathematicians in Relativity

7. Albert Einstein was the other physicist who was involved in this thought experiment. THOUGHT EXPERIMENT

8. Law of inertia was given by Galileo Galilei, not Isaac Newton. Entropy is an arrow of time (from 2nd law of thermodynamics).

Observer effect is real. An observer can manipulate the experiment only by the mere act of observation. How Humans Perceive things with Relativity

9. Carl Sagan became popular worldwide after his show Cosmos.

10. Russian astronauts are called cosmonauts. More space articles here
