Answer the following questions . a. The earth's magnetic field varies from point is space. Does it also change with time ? It so , on what time scate does it change appreciably ? b. The earth's core is known to contain iron. Yet geologists do not regard this as a source of the earth's magnetism why ? c. The charged currents in the outer conducting regions of the earth's core are thought to be responsible for earth's magnetism . What might be the ' battery ' (i.e., the source of energy) to sustain these currents ? d. The earth may have even reversed the direction of its field several times during its history of 4 to 5 billion years. How can geologists know about the earth's field in such distant past ? e. The earth's field departs from its dipole substantially at large distances (greater than about 30,000 km) what agencies may be responsible for this distortion ? f. Interstellar space has an extremely weak magnetic field of the order of 10^(-12) T, Can such a weak field be of any significant consequence ? Explain.

In Fig (a) , the V_(BB) supply can be varied from 0 V to 5.0 V . The Si transistor has beta_(dc) = 250 and R_(B) = 100 kOmega , R_(C) = 1 k Omega , V_(C C) = 5.0 V . Assume that when the transistor is saturated , V_(CE) = 0V and V_(B E) = 0.8 V . Calculate (a) the minimum base current , for which the transistor will reach saturation .
