Answer:
J. 0-1 sec
Explanation:
When stone is moving up, it stops in the highest point (speed=0 m/s) before falling down. Because the acceleration of gravity is directed down.
So, the highest speed 0-1 sec.
Answer:
KE = KE (incidental) - KE of emitted photons
or KE = h * f - Wf
So h * f = KE + Wf = 1.2 + 1.88 = 3.08 incident energy
If you double the frequency then h * f = 6.16
KE = 6.16 - 1.2 = 4.96 eV
The Levels of Classification. Every organism can be classifiedat 7 different levels - kingdom, phylum, class, order, family, genus and species. Each level contains organisms with similar characteristics. The kingdom is the largest group and very broad
False. longitudinal move parallel to the movement of wave.
