Answer: (a) The boat sinks a little more in water so that the weight of new volume of water displaced by the boat equalizes the weight of the boat and the boy.
(b) The weight of the water displaced by submerged part of the boat increases. It is now equal to sum of weight of boy and weight of boat.
(c) The buoyant force acting on the boat increases. The new buoyant force is equal to sum of weight of boy and weight of boat.

A metal box is made up of an alloy of zinc and copper metals. It weighs 302 g and 320 g in a liquid of relative density 1.4 and water, respectively. The specific gravities (or relative densities) of zinc and copper are 7.4 and 8.9, respectively. Arrange the following steps in a proper sequential order to find the masses of metals in the alloy.
(a) Find the weight of the box in a liquid of relative density 1.4 and water along with the relative densities of zinc and copper from the information given in the problem
(b) Note down the metals present in the metal box.
(c) Let the masses and volumes of copper and zinc be and respectively. The weight (w) and volume (v) of the box would be equal to and , respectively.
(d) The relative density of liquid find the value of ‘w’.
(e) The density of the alloy used for the box is, substitute and , find the masses of and .

We know that more water evaporates when the weather is hot. In such a situation, the stomata begin to close. This lessens the amount of water that evaporates from the leaves. Fig-4: Stomata in the leaf We learned in the chapter 'Nutrition in Plants' of class VII that plants absorb carbon dioxide. The carbon dioxide also enters the leaves through the stomata. - When the weather is hot and the stomata close, what effect would this have on the absorption of carbon dioxide by the plant? - What effect would a change in the amount of carbon dioxide absorbed have on the growth of the plant? - If the plant does not get water at this time, what effect would this have on its growth? Discuss in your class and find out reasons. Plants cannot absorb nutrients directly from soil. Only the nutrient that dissolves in water is absorbed by the roots of the plant. We discussed about transportation of substances in the chapter, "Transportation through plasma membrane" and in the chapter "Plant Cell". Try to think of how xylem and phloem are useful in transportation. - Water is essential for Agriculture.
