Answer:
a) v = 21.34 m/s
b) v = 21.34 m/s
c) v = 21.34 m/s
Explanation:
Mass of the snowball, m = 0.560 kg
Height of the cliff, h = 14.2 m
Initial velocity of the ball, u = 13.3 m/s
θ = 26°
The speed of the slow ball as it reaches the ground, v = ?
The initial Kinetic energy of the snow ball, 
Potential energy of the snow ball at the given height, PE = mgh
Final Kinetic energy of the ball as it reaches the ground, 
a) Using the principle of energy conservation,
b) The speed remains v = 21.34 m/s since it is not a function of the angle of launch
c)The principle of energy conservation used cancels out the mass of the object, therefore the speed is not dependent on mass
v = 21. 34 m/s
The process that water redeposit into a lake in the form of rain is precipitation.
<h3>What is water runoffs?</h3>
Water runoff occurs when there is more water than land can absorb.
The water flows across the surface of the land and into nearby creeks, streams, or lakes.
Runoff can come from both natural processes and human activity.
When rain falls to the earth from clouds and runs downhill into rivers and lakes.
During evaporation, the water turns from liquid into gas, and moves from oceans and lakes into the atmosphere where it forms clouds.
<h3>What is precipitation?</h3>
Precipitation is any liquid (rain) or frozen water that forms in the atmosphere and falls back to the Earth, for example it could fall on land or into lakes and rivers.
Thus, the process that water redeposit into a lake in the form of rain is precipitation.

Preserved fossil<span> (like a fossil in amber, ice or tar.</span>
Nulceus - recipe book/instruction manual
Mitochondria - Battery
Endoplasmic reticulum - Printer or a pen?
Golgi aparatus - an envelope
Chloroplasts - green rechargable battery
Cell membrane (elastic band (2 to represent the phospholipid bilayer)
Ribosomes - I guess maybe an ink pot as its the material thats used to write
Cell Wall - the paper bag
lysosomes - washing up liquid (breaks down wate food on a dirty plate)
vaculoes - bottle of water
It is C) because that truck has more mass
