A rock, mass = 2.0 kg, is fired straight up at 60 m/s from a catapult (not a safe thing to do). What will be its maximum height at the moment it stops going up and starts to come down? Use the magnitude of g to be -10m/s2.

180 m

3600 m

360 m

-540 m

540 m

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
