A small conducting rod of length l, moves with a uniform velocity v in a uniform magnetic field B as shown in figure.
A The end X of the rod becomes positively charged.
B The end Y of the rod becomes positively charged.
C The entire rod is unerringly charged.
D The rod becomes hot due to joule heating.
By Fleming's right-hand rule, current flows from X to Y, but which end actually receives the extra positive charge?
Refer to the given food web.

later. It is observed that container X has a much lower
temperature than container Y. Which of the following
are the possible reasons?

Values of ignition temperatures of different substances are listed in the given table.
Increasing order of the inflammability of the given substances is
AI < IV < II < III
BIII < II < IV < I
CIV < I < III < II
DII < III < I < IV
It should be A only because inflammable substances catch fire without heating them.
The given diagram represents the water cycle. Select the correct option regarding the processes that are labelled as 'a', 'b' and 'c'.
A In processes 'a' and 'b', one state of water changes into another state.
BIn process 'a', the state of water with fixed volume changes to the state of water which does not have fixed volume.
CIn process 'c', liquid or solid state of water may fall on Earth's surface.
DAll of these
