Answer:
3.25 m
Explanation:
t = Time taken = 0.166 seconds
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration = 9.81 m/s²
s = 1 because meter stick is 1 meter in length
Here, the initial velocity of point B is calculated from the time which is given. This velocity will be the final velocity of the acorn which falling from point A.
The distance of the acorn from the ground is 1.87+1.38 = 3.25 m
A.cooler and hotter rock rise but do not sink.
B.hotter and cooler rock sink but do not rise.
C.hotter rock rises and cooler rock sinks.
D.cooler rock rises and hotter rock sinks.
hotter rock rises and cooler rock sinks.
Answer: Option C.
<u>Explanation:</u>
The process that happens inside the surface of earth makes the rocks inside the surface to either expand or shrink in size because of the presence of heat inside the surface.
Heat rises and as the warmer rock gets further away from the super heated center of the Earth it begins to cool off and starts to sink back toward the super heated center of the Earth where it is reheated and the whole process starts over again. That is what a convection current is.
