C and Si both have same lattice structur...

C and Si both have same lattice structure, having 4 bonding electrons in each. However, C is insulator where as Si is intrinsic semiconductor. This is because, …….

A

in case of C the valence band is not completely filled at absolute zero temperature .

B

in case of C the conduction band is partly filled even at absolute zero temperature.

C

the four bonding electrons in the case of C lie in the second orbit, whereas in the case of Si they lie in the third.

D

the four bonding electrons in the case of C lie in the third orbit, whereas for Si they lie in the fourth orbit.

Text Solution

Verified by Experts

The correct Answer is:
C
the four bonding electrons in the case of C lie in the second orbit, whereas in the case of Si they lie in the third.

Two spherical conductors B and C having equal radii and cayying equal charges on them repel each other with a force F when kept apart at some distance. A third spherical conductor having same radius as that B but uncharged is brought in contact with B, then brought in contact with C and finally removed away from both. The new force of repulsion between B and C is

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student speculates that the constant C depends on :- (i) The angle at which the ball was launched (ii) The ball's mass (iii) The ball's diameter If we neglect air resistance, then C actually depends on :-
