What is thecommon-mode rejection ratio of an LF157A at low frequencies?
100dB
Is pipe round because it provides the least surface area to volume ratio?
More likely because it's easier to manufacture, much easier to put threads on, you don't have to worry about orientation when you put them together, and they have no weak spots created by corners. My gutter pipes are rectangular because they don't stick out as far from the house as a circular one with the same area. But they are low enough in the pressure they contain that they can be formed from sheet metal with a crimped seam. Making a water supply pipe that way would be impossible. And it's easy to keep them aligned to the house. Running a rectangular water main under a street would be a major pain.
What happens if air to fuel ratio becomes higher?
low power genaration
Why poisson's ratio cannot be greater than 0.5?
If you stretch an object, each side changes length by an amount due to strain,e, so the new length is L(1+e)..Each side normal to the stretch direction contracts by an amount equal to poisson ratio x the stretch. If you calculate the change in volume V you get dV = Ve(1-2u) Ay u = 0.5 there is no volume change (incompressible); if it were greater than 0.5 volume would decrease which is unlikely. If it is 0, there is no lateral contraction and volume increases. If less than 0 the object will actually expand laterally rather than contract, and some special materials do this. Poisson ratio can be as low as -1, but most common materials lie between 0 and 0.5
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
Do leaves have a low or high surface area to volume ratio?
high
Why is surface area an important characteristic of a cell?
a low surface to volume ratio doesn't waste membrane material
A sphere with a ratio of surface area to volume equal to 0.15m-1 a right circular cylinder with a ratio of surface area to volume equal to 2.2m-1?
The sphere has a surface area-to-volume ratio of 0.15m^-1, which means it has a relatively low surface area compared to its volume. This indicates a more compact shape. On the other hand, the right circular cylinder with a ratio of 2.2m^-1 has a higher surface area compared to its volume, suggesting it is more elongated or spread out.
How does the surface area to volume ratio change as the cell size increases?
It decreases. As the dimensions increase by a number, the surface area increases by the same number to the power of 2, but the volume increases by the same number to the power of 3, meaning that the volume increases faster than the surface area.
What happens the surface to volume ratio when the cell becomes larger?
When cells get smaller, the volume (as well as mass) decreases faster than the surface area so the surface:volume increases. Cells with a high surface:volume are more effective in receiving nutrients through diffusion. A cell (assume perfect sphere) with radius 2 has a surface area of 16pi and volume of 32pi/3. A cell with radius 3 has a surface area of 36pi and volume of 108pi/3. Also relatively speaking, volume can be thought of as y=x3 and surface area as y=x2. When there is a change in x, the change is more dramatic in the volume, so small cells have high ratios and large cells have low ratios.
Do the lungs have a high or low surface area to volume ratio?
High - each branch inside the lungs sub-divides many, many times. This dramatically increases the surface area in relation to the actual volume.
How does a small surface area per unit volume help cacti live in areas that are dry for long periods of time?
Any living thing that has a low surface area per unit of volume will lose less moisture to evaporation than a living thing with a high surface area to volume ratio.
Why is it bad for a cell's surface area to volume ratio to be too low?
A low surface area to volume ratio can lead to inefficient exchange of nutrients and waste products. This can hinder the ability of the cell to efficiently take in nutrients and eliminate waste, potentially affecting its overall function and survival.
What problems does a big cell have surface area to volume ratio?
A big cell with a low surface area to volume ratio may have trouble efficiently exchanging nutrients and wastes with its environment. This could lead to difficulties in regulating internal conditions and could hinder the cell's overall metabolic processes. Additionally, a low surface area to volume ratio may limit the cell's ability to transport molecules across its membrane effectively.
How does the ratio of surface area and volume relate to the problems of growing cells?
The rate at which the cell increases in size depends on the DNA. The ratio of the surface area (calculated: length x width x # of sides) is divided by the cell volume (calculated: length x width x height). THE VOLUME OF THE CELL INCREASES MORE RAPIDLY THAN THE SURFACE AREA, CAUSING THE RATIO OF SURFACE AREA OVER VOLUME TO DECREASE. This decrease causes cell malfunction. If the cell volume increases too much, then the ratio will decrease causing problems for the cell's regular functions.
How does surface volume ratio relate to a limit on cell expansion?
If a surface area:volume ratio gets too small, then it is difficult for the cell to absorb/expell substances, and substances must travel a long way to exit or leave the cell. This means that a cell will want a large surface area:volume ratio. However, the surface area:volume ratio decreases as a cell expands. Because of this, a cell will reach a certain point where expanding any more will cause the cell to become inefficient due to its low surface:area to volume ratio. Therefore, cells are limited by the efficiency of their ratio; they will not grow to a size where their ratio becomes too inefficient.
Why is surface to volume ratio important to organisms?
surface area to volume is an important concept in biology because cells get their nutrients by difusing it in through their membranes so it is easier for a cell with a better S.A:V to difuse more stuff in in comparison to it's needs
