The given figure shows a V shaped wire lying in x - y plane. A current of I ampere flows in the wire. The direction of the magnetic field at point P which lies in the same plane is along
Tanmay heated a bimetallic strip made up of metal X and metal Y. After a few minutes, he observed that it curled as shown.
What can be concluded from this experiment?
A Metal X expands more than metal Y.
B Metal Y expands more than metal X.
C Metal X expands and metal Y contracts.
D Metal Y expands and metal X contracts.
The diagram shows a beaker containing a solution of zinc sulphate and two carbon electrodes. A battery is placed next to it. In order that the electrode P be plated with zinc,
A P must be connected to S and Q to R
B P must be connected to Q and S to R
C P must be connected to R and Q to S
D P and Q must be connected to R.
The answer would be a as znso4 wold breakdown into zn 2and so42-ions .the zn 2 would be attracted towards cathode(negative terminal) so p would be attached to negative terminal and therefore the answer is a.

The quality of sound produced by a tuning fork is different from that produced by a musical instrument because of difference in
the tuning fork produces a shriller sound than musical instruments.As pitch is the characteristic which determines the shrillness of a sound,the answer can be d. At the same time as frequency of a vibrating body determines its pitch the answer can also be b.
