What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
How can you obtain a cell's ratio of surface area to volume?
To obtain the ratio of surface area to volume, divide the surface area by the volume.
Why sphere has minimum surface area for given volume?
The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of ​​the body, there are N +1 is smaller the surface area of ​​the surface When N tends to infinity for a long time, Serve the sphere surface. ------mecose
What is ratio of surface area to volume?
surface area/ volume. wider range of surface area to volume is better for cells.
What is the mathematical name for surface area?
it is still surface area
What can change the speed at which chemical reactions take place?
Enzymes EDIT from a different person: No! Catalysts, Temperature, Pressure, Concentration, Surface Area.
How does breaking up a solid speed dissolving in liquid?
By breaking up the solid, you are creating more surface area. Therefore, increasing the surface area will speed up dissolution.
Does surface area affect how fast a substance dissolves?
Yes, it is normal; a great surface area improve the speed of dissolution.
Will the speed of moving object affected by the area of surface contacted?
Yes.
Will a smaller surface speed up a chemical reaction?
No. A smaller surface area will slow down a chemical reaction.
The speed with which wastes are produced by a cell depends on the cell's what?
it depends on its surface area
How do the amount of a rock's surface area affect its rate of weathering?
A rock with a larger surface area will weather more rapidly than a rock with a smaller surface area. This is because weathering occurs at the surface of the rock, so more surface area means more exposure to weathering agents like water and air. As a result, rocks with more surface area will break down and deteriorate faster.
How does folding the small intestine help to speed up absorption?
Folding the small intestine into numerous finger-like projections called villi increases the surface area available for absorption. This allows for more contact between nutrients and the absorptive cells, speeding up the process of absorption into the bloodstream. Additionally, the presence of microvilli on the surface of the absorptive cells further enhances absorption efficiency.
Does the size of the reactants affaect the speed of a chemical reaction?
Yes. The more surface area that is exposed, the greater the speed of the reaction.
Does fluid friction vary with speed and area contact?
Fluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
The speed of a person parachuting when the surface area of the parachute is 100 square feet?
The decent rate will be significantly high on an open parachute because a 100 square foot parachute is considered to be very small. Therefore the wing loading is high and it is more likely to be a high performance parachute. High performance parachutes have a higher angle of attack and generally need to do a swoop (dive) landing to pick up enough wing speed for a safe landing. On touch down, the decent rate is the same as any other parachute for obvious reasons.
Why does crushing a substance speed up reaction rate?
You are increasing the surface area for the substance to react
