1. Where does a thermocline form? a. at the surface of a lake, keeping the water cooler than the air
b. at the bottom of a lake, preventing water from soaking away
c. between a top warm layer of water and a bottom cold layer of water in a deep lake
d. between a bottom warm layer of water and a top cold layer of water in a deep lake

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

explanation:

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
