Answer
I'll help with part a.
Convert revolutions per minute to revolutions per second. Next, convert from revolutions per second to radians per second. Finally, plug the numbers into the formula for angular velocity (this involves the diameter/radius value)
I believe it would be (if x was the number):
x - 5 ≥ -28. Hope this helps!
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:
V α 1/P
To change it to an equality, we introduce a proportionality constant, k. We do as follows:
V = k/P
So, to determine what is asked, we need to first calculate for the value of k.
V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280
Thus, at P = 87 cmHg
V = 17280 / 87
V = 198.62 m^3
