4. you've been given an elephant, you can't give it away or sell it. what do you do with it?
5. if you were a tree, what kind of tree would you be and why?
6. you finish an interview for a job and step out of the office and find a lottery ticket that ends up winning $10 million. what would you do with the money?
7. what's the color of money?
8. if you had to be shipwrecked on a deserted island, but all your human needs -- such as food and water -- were taken care of, what two items would you want to have with you?
9. are you a hunter or a gatherer?
10. if you had a choice between two superpowers, being invisible or being able to fly, which would you choose and why?

these are just random questions i thought of. answer freely, there are no wrong answers : )

Which statement best explains why an object weight less on mercury than it does on earth

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
