A small force can create a large pressure if its area is large.

In the transpiration pull theory, what causes the tension that leads to lifting of the water column?

Study the given figure of water movement in the leaf and mark the correct series of pressure gradient that occurs during transpiration. (I) Pressure gradient between the outside air and th air spaces of the leaf. (II) Pressure gradient between photosynthetic cells and on the water filled xylem in the leaf vein.

A large cylindrical vessel contains water to a height of 10 m. If is found that the thrust acting on the curved surface is equal to that at the bottom. If atmospheric pressure can support a water column of 10 m. the radius of the vessel is

Water is filled up to a height h in a beaker of radius R as shown in the figure. The density of water is rho, the surface tension of water is T and the atmospheric pressure is P_0. Consider a vertical section ABCD of the water column through a diameter of the beaker. The force on water on one side of this section by water on the other side of this section has magnitude

There is no relation between the stoichiometry of the reaction and order of the reaction, order is always experimently calculated. Monitoring of the progress of the reaction can be done by pressure measurement ( P_0,P_t & P_oo are total pressure of reaction mixture at time, t=0, t=t & t=oo ) .All following reactions in Column-1 have half life 5 minutes. Select incorrect combination for I^(st) order reaction :

The human ciculatory system can be thought of as a closed system of interconnecting pipes through which fluid is continuously circulated by two pumps the two pumps the right and left verticles of the heart, work as simple two-stroke force pumps. The muscles of the heart regulate the force by contracting and relaxing. the contraction (systole) lasts about 0.2s and a complete systole/diastole (contraction/relaxation) cycle lasts about 0.8s. For flood pressures and speeds in the normal range. the volume flow rate of blood through a blood vessel is directly proportional tot he pressure difference over a length of the vessel and to the fourth power of the radius of the vessel. The total mechanical energy per unit volume of blood just as it leaves the heart is E//V=rhogh+P+rhov^(2) Q. Why is diastolic blood pressure muchh lower than systolic pressure? A. because the heart exerts more force on the blood during diastole B. Because the heart exerts no force on the blood during diastole C. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same. D. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same.
