Im not sure, but here are a few of mine : Learn to be silent, and listen, take massive action and be proactive, listen, focus, and lastly, persist. Hope this helped! (:
Answer:
The answer is D.
Explanation:
Just like how cold air falls and warm air rises the same is with water.
Also the places with the coldest water is the north and south pole. The equator is relatively always warm so yeah.
Answer:
4.5 Nm (Anticlockwise)
Explanation:
Let the 75 kg kid is sitting at the left end and the 60 kg kid is sitting on the right end.
Anticlockwise Torque = 75 x 1.5 = 112.5 Nm
clockwise Torque = 60 x 1.8 = 108 Nm
Net torque = Anticlockwise torque - clockwise torque
Net Torque = 112.5 - 108 = 4.5 Nm (Anticlockwise)
a) x = 
at t = 5s

b) v = 
= 
at t = 5 s
v = 
c) a = 
= 28 - 12t
at t = 5 s
a = 28 -12*5= 28-60= -32 m/
d) At maximum positive coordinate velocity = 0
So, 

At t = 4.66 s

e) At t = 4.66 s
f) At maximum positive velocity a = 0


At t = 2.33 s
V = 
g) t = 2.33 s
h) When particle is not moving v = 0
So 

At t = 4.66 s
a = 
i) At t = 0s, X =0m
t = 5s, X = 100m
So, Displacement = 100m
Velocity =
