Answer:
0.56cm
Step-by-step explanation:
a capillary tube has a cylindrical shape. So we need the formula for the volume of a cylinder:
where is a constant,
is the radius of the cylinder (the capillary), and is the length (in this case the length of the mercury thread )
since we need the radius, we solve for it in the last equation:
The information that we already know is:
so we substitue this values:
the radius of the capillary tube is 0.56cm
Answer:(-5,1)(2,2)
Step-by-step explanation:
distribute the -1 and 2
(-5,1) (2,2)
Answer:
x=20
Step-by-step explanation:
Since they are congruent triangles
A = D
3x-10 = 2x+10
Subtract 2x from each side
3x-10-2x = 2x+10-2x
x-10 = 10
Add 10 to each side
x-10+10 = 10+10
x=20
