Describe the sample space for the indicated experiment in the following : Consider the experiment in which a coin is tossed repeatedly until a head comes up .

Ornithologists observed decline in the bird population in an area near a lake after the setting of an industrial unit in the same area. Explain the cause responsible for the decline observed.

A 20muF capacitor is charged to 30 V of potential. The battery is then disconnected and a 200 mH of coil is connected across it, so that LC oscillations are set up. Calculate the frequency of the oscillations are set up. Calculate the frequecy of the oscillatios set up and the maxium current in the coil.

Describe those factors which are responsible for variation in the value of acceleration due to gravity 'g' ?

A coin is tossed once. Then, if it turns up a head a die is thrown once : if it turns up a tail it is tossed twice more. Describe : the sample space S of the experiment.

An appratus was set up as shown in the figure. It was observed that when an aqueous solution of HCl was taken in the beaker and the circit was closed, the bulb in the circuit began to glow, but it did not glow when the experiment was repeated with glucose solution. what could be the reason? Would the bulb glow if the same experiment is repeated with an aqueous solution of NaOH? why?
