Answer: 11.1cm
Explanation:
Object distance (u) = 32cm
Image distance(v) = 17cm
Focal length(f) =?
Lens formular:
1/f = 1/u + 1/v
1/f = 1/32 + 1/17
Taking the L. C. M of 17 and 32
1/f = (17 + 32) / 544
1/f = 49/544
Taking the reciprocal
f = 544/49
f = 11.1 cm
Therefore, Focal length of the lens is 11.1cm

The latent heat of fusion refers to the solid to liquid or liquid to solid states.
Answer: Option C
<u>Explanation:
</u>
It is known that the inter conversion process from the states of solid to liquid is referred as fusion. So, for these conversions, the external energy in the heat form should be supplied to solid.
This external energy should be greater than the latent heat of solid in order to successfully break the bonds to form liquid. So the change in the enthalpy of the reaction while conversion from solids to liquids are termed as latent heats of fusion.
Even the inter-conversion from liquid to solid state will undergo change in enthalpy where the heat will be released and that is termed as latent heats of solidification. It is found that latent heat of solidification is equal in magnitude but opposite in direction with the latent heats of fusion.
The correct answer for the question that is being presented above is this one: "(a)4." Suppose that during any period of 1/4 second there is one instant at which the crests or troughs of component waves are exactly in phase and maximum <span>reinforcement occurs, in 1 second, there will be 4 beats.</span>
