Mohini, a resident of Chandigarh went to Shimla with her parents. There she same plant that they have in their backyard, at home. However, she observed that while the plants in their backyard bore white flowers, those in Shimla had pink flowers. She brought home some seeds of the plant from Shimla and planted them in Chandigarh. Upon performing self breeding for several generation she found that the plant from Shimla produced only white flowers. (a) According to you what might be the reason for his observation-genetic or eavironmental factors ? (b) Suggest a simple experiment to determine whether this variation is genetic in nature (c) Suggest another experiment to check whether this variation in flower color is due to environmental factors

Figure below shows a shampoo bottle in a perfect cylindrical shape In a simple experiment, the stability of the bottle filled with different amount of shampoo volume is observed. The bottle is tilted from one side and then released. Let the angle theta depicts the critical angular displacement resulting in the bottle losing its stability and tripping over. Choose the graph correctly depicting the fraction f of shampoo filled (f= 1 corresponds to completely filled) vs the tripping angle theta

A car manufacturer usually tells a optimum speed (V_(0)) at which the car should be driven to get maximum mileage. In order to find the optimum speed for a new model, an engineer of the car company experimented a lot and finally plotted a graph between the extreme time t (defined as number of hours a tank full of petrol lasts) vs the constant speed V at which car was run. (a) Calculate the optimum speed V0 for this new model. (b) If the fuel tank capacity of this car is 50 litre, what maximum mileage can be obtained from this car?

a) The anlge subtended at the eye by an object is equal to the angle subtended at the eye by the virtual image produced by a magnifying glass. In what sense then does a magnifying glass provide angular magnifications? b) In viewing through a magnifying glass, one usually positions one's eyes very close to the lens. Does angular magnification change if the eye is moved back? c) Magnifying power of a simple microscopes is inversely proportional to the focal length of the lens. What then stops us from using a convex lens of smaller and smaller focal length and achieving greater and greater magnifying power? d) Why must both the objective and the eyepiece of a compound microscope have short focal lengths? e) When viewing through a compound microscope, our eyes should be positioned not on the eyepiece but a short distance away from it fot best veiwing. Why? How much should be that short distance between the eye and eyepiece?
