A primary root grows from 5 cm to 19 cm in a week. Calculate the growth rate and relative growth rate over the period.

Show absolute and relative growth rate with the help of figure.

Describe briefly: Absolute and relative growth rates

A rectangular container, whose base is a square of side 5 cm, stands on a horizontal table, and holds water up to 1 cm from the top. When a cube is placed in the water it is completely submerged, the water rises to the top and 2 cubic cm of water overflows. Calculate the volume of the cube and also the length of its edge.

In a reaction, 2A rarr Products , the concentration of A decreases from 0.5 mol L^(-1) to 0.4 molL^-1 in 10 minutes. Calculate the rate during this interval?

Fig. TBQ 8.1 shows a capacitor made of two circular plates each of radius 12 cm, and separated by 5.0 cm. The capacitor is being charged by an external source (not shown in the figure). The charging current is constant and equal to 0.15 A. Calculate the capacitance and rate of change of potential difference between the plates.

Water is leaking from a conical funnel at a uniform rate of 4 cm^3//sec thorugh at small hole at the vertex. When the slant height of the water in the funnel is 3 cm, find the rate of decrease of the slant height of water given that semi vertical angle of the cone (funnel) is 30^@ .

Water is leaking from a conical funnel of semi-vertical angle pi/4 at a uniform rate of 2 cm^2//sec in the surface area curved), through a tiny hole at the vertex of the bottom. When the slant height of the cose is 4 cm, find the rate of decrease of the slant height of water.

Figure 8.6 shows a capacitor made of two circular plates each of radius 12 cm, and separated by 5.0 cm. The capacitor is being charged by an external source (not shown in the figure). The charging current is constant and equal to 0.15A. Calculate the capacitance and the rate of change of potential difference between the plates. :
