between X and P
Between P and Y
Between Y and Z
Outside W
Outside Z
Correct answer is B
The image produced by a convex mirror is always virtual, and located behind the mirror.
When the object is far away from the mirror the image is upright and located at the focal point.
67cm
73cm
949cm
952cm
955cm
Correct answer is E
Atmospheric pressure = 70cmHg (which is the height of mecury)
pressure = pgh = pwghw
Where
Pw = density of water
hw = height of water
ph = pwhw
13.6*70 = 1*hw
hw = 952cm
Pressure of gas in cm of water = 952 + 3 = 955cm

slope of line PQ
Reciprocal of either OP or OQ
Length OP or OQ
area under the graph E ratio OP/OQ
Correct answer is B
The intercept on either of the axes of the graph of \(\frac{1}{u}\) against \(\frac{1}{v}\) gives the value of \(\frac{1}{f}\). Hence, the reciprocal of this intercecpt gives the value of the focal length.
