When a spherical cell increases in diameter from 2 micrometers to 20 micrometers by what factor does its volume change?
The formula for volume of a sphere is (4/3)(pi)r3, where r is the radius. The initial volume of the sphere is then (4/3)(pi)(1)3 and the final volume is (4/3)(pi)(10)3. (Remember that we are given diameters, and need to divide them by two to find the radii to plug into the equations.)
The factor by which the volume changes is (Final Volume)/(Initial Volume), which is this case is
[ (4/3)(pi)(10)3 ] / [ (4/3)(pi)(1)3 ]
(4/3)pi cancels out, leaving 103 / 13 = 1000.

When a spherical cell increases in diameter from 2 um to 20 um by what factor does it's surface area change?
It depends on what a female's breath smells like, how big her mouth is when she opens it really wide, what her tongue looks like, smells like, and feels like when she gives you a Big lick (depends on how warm, wet, and slimy her tongue and saliva is).
A spherical balloon of 0.5m diameter contains air at a pressure of 500kpaThe diameter increases to 0.55m in a reversible process during which pressure is proportional to diameter.Determine the work do?
To determine the work done during the reversible expansion of the balloon, we can use the formula for work done in a process where pressure is proportional to diameter. The initial diameter is 0.5 m, and the final diameter is 0.55 m, with initial pressure ( P_1 = 500 , \text{kPa} ). The average pressure during the expansion can be calculated as ( P_{avg} = \frac{P_1 + P_2}{2} ), where ( P_2 ) can be found using the proportional relationship. The work done ( W ) can then be calculated using ( W = P_{avg} \cdot \Delta V ), where ( \Delta V ) is the change in volume between the two diameters. However, without calculating the new pressure ( P_2 ), we cannot provide a numeric answer. If you want, I can further assist with that calculation.
When mass and volume change what happens to the density?
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
Do you multiply or divide to change um to mm?
To convert micrometers (um) to millimeters (mm), you divide by 1,000. This is because there are 1,000 micrometers in a millimeter. So, for example, to convert 500 um to mm, you would calculate 500 um ÷ 1,000 = 0.5 mm.
How far is micrometers to millimeter and what direction does the decimal move?
To change from a micrometre to a millimetre you need to move the decimal point 3 places to the left.
When a spherical cell increases in diameter from 2 micrometers to 20 micrometers by what factor does its surface area change?
If the diameter doubles, the surface area quadruples (x 4). So if the original surface area is 3 units, new one will be 12 units!soooo the answer is 12 units
When a spherical cell increases in diameter from 2um to 20 um by what factor does its surface area change?
The surface area will increase one hundred fold.
How does the surface area change compared to the volume as a cell gets larger?
Surface area increases as the square of the diameter, whereas the volume increases by the cube.
If a cell measures 10 micrometers at 100x what is its length at 200x?
At 100x magnification, the cell appears as 10 micrometers. When the magnification increases to 200x, the cell will appear twice as big as before. Therefore, at 200x magnification, the length of the cell will be 20 micrometers.
How do you change cubic micrometers to liters?
Cubic micrometers x (1.0 × 10-15) = liters
How does pressure change with variations in flow rate and diameter in a fluid system?
In a fluid system, pressure increases with higher flow rate and decreases with larger diameter.
How does pressure change with pipe diameter?
As pipe diameter increases, pressure decreases. This is because the same amount of fluid is flowing through a larger area, resulting in lower pressure.
Is there change in internal diameter of hollow cylinder on heating it?
Yes. If, as for most common substances, the outside diameter of the cylinder increases on heating, the inside diameter will increase by the same percentage. This fact is used to shrink-fit pulleys to shafts.
Consider a balloon that is being inflated As the balloon increases in size the area of its surface increases Each time the balloon's diameter doubles what do you expect for the change in the area?
For any geometric figure, surface area is proportional to (linear dimensions)2 .As the balloon's diameter doubles, its area increases by the factor of (2)2 = 4 .

What conditions might cause blood vessels to change diameter?
Blood vessels can feel the shear stress caused by blood flow. When shear stress increases the blood vessel responds and the diameter becomes larger. Thus in short, changes in blood flow might cause blood vessels to change diameter.
What temperature change is required to increase its volume by a spherical steel ball bearing had a diameter of 2.540 cm at 25 oC. What is its diameter when its temperature is raised to 100 oC?
The volume change of a sphere can be calculated using the formula V = 4/3 * π * r^3, where r is the radius. The temperature change required to increase the volume can be calculated using the coefficient of thermal expansion of steel. The diameter of the steel ball bearing at 100°C can be calculated using the volume change and the new temperature, considering the change in radius.
