The two elementary particles that have nearly infinite life time are: Electron and proton.
Briefly state how does the elevation and air pressure affects the boiling point of water?
Joule's laws (J.P. Joule) Joule's first law: The heat Q generated whenever a current I flows via a resistance R for a specified time t is specified by: Q = I2

Briefly state the definition of Pascal’s principle?
Simultaneity principle: The principle which all frames of reference will contain invariant simultaneity; that is, the two events perceived as simultaneous (that is, containing the similar time coordinate) in one frame will be apparent as simultaneous
Calculate the hot and cold temperature after 25 orbits. Assume a 100kg spherical spacecraft made of aluminum. Assume that the spacecraft is in an equatorial orbit. How is calculation 1 different for a spacecraft in a 90 degree (polar) orbit?
Explain in short why electron and proton encompass similar charge while the proton is 1836 times heavier?
