Answer:
If we assume a temperature of 20ºc and the blood interfacial surface tension is similar to water interfacial surface tension, the diameter of the capillary tube should be 0.933mm.
Step-by-step explanation:
The Jurin law describes the height a fluid can reach in a capillary tube. This law can be written as:
where γ is the interfacial surface tension, θ is the contact angle with the fluid, ρ is the fluid density, g is the gravity acceleration and r is the tube radius.
If we assume that the interfacial surface tension of blood and water are almost the same, γ=0,0728 N/m at 20ºc. Therefore the diameter of the tube will be:

Answer:
C
Step-by-step explanation:
All of the offered answer choices are dilations. When a figure is dilated about the origin, every individual coordinate is multiplied by the dilation factor.
So, the dilation factor can be found by dividing an image coordinate by the pre-image coordinate.
I'x/Ix = -3/-2 = 1.5
The dilation is 1.5 about the origin. . . . matches C
Answer:
23.9 ft (nearest tenth)
Step-by-step explanation:
Use the sine trig ratio to find the length of the ramp.
where:
is the angle- O is the side opposite the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- = 4.8°
- O = height of ramp = 2 ft
- H = length of ramp
Substituting the given values into the formula and solving for H:
