Answer: 17. is A and 18 is most likely G
Step-by-step explanation:
The angular velocity is the linear speed divided by the radius.
ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
ω = 45 degrees/second
Answer:
BC=11
Step-by-step explanation:
we need to find BC
and we know that
AB= x+2
AC=13
BC=2x+11
A, B and C are collinear
that means that
AB+BC=AC
x+2+2x+11=13
3x+13=13
3x=0
x=0
so BC=2(0)+11
BC=11
a) 2/5(n)=6 n=15
b) 4/7(x)=16/3 x=28/3 x=9.33333 x=9 1/3
any option for b works
i hope this is right and helps
We first assume that this gas is an ideal gas and we use the ideal gas equation to determine the answer. It is expressed as:
PV = nRT
Molar volume can be obtained from the equation by V/n.
V/n = RT/P
Therefore, the correct answer from the choices listed above is option A, <span>at 273 K and at 2.0 atm.</span>
