Although all ballet positons involve turned out feet, the simplest one is first position. Heels are touching and toes face out, as far away from each other as possible (close to 180 degrees of rotation).
Is this your own answer after the 2 points because if so i would say that is a good answer exept for keeping mountains from growing but they do cause giant black clouds that can block sunlight from the ground below

It should go to 100 that fast nor 40
Scientist would check what other scientists have said before they come up with their own scientific question. That way they can record the results from the others and compare them with their own findings when they conduct their own experiments and record the findings.
Answer:
a)
b)
.
Explanation:
Given that
Boyle's law
P V = Constant ,at constant temperature
a)
Given that


We know that for PV=C

Now by putting the values
PV= 50 x 0.106

Where P is in KPa and V is in 
b)
PV= C
Take ln both sides
So 
lnP + lnV =lnC ( C is constant)
By differentiating

So

When P= 50 KPa

It indicates the slope of PV=C curve.
It unit is
.
Or we can say that
.
