Statement I: The bulb of one thermometer is spherical while that of the other is cylindrical . Both have equal amounts of mercury. The response of the cylindrical bulb thermometer will be quicker.
Statement II: Heat conduction in a body is directly proportional to cross-sectional area.

A

Statement I is true, Statement II is true and Statement II is the correct explanation for statement I.

B

Statement I is true, statement II is true and statement II NOT the correct explanation for Statement I

C

Statement I is true, Statement II is false.

D

Statement I is false, statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Both are true and Statement II explains Statement I because for same volume surface area of the cylindrical bulb will be more.

Out of two thermometers one with spherical bulb and another with cylindrical bulb, which will respond quickly to temperature changes?

Statement I: The thermal resistance of a multiple later is equal to the sum of the thermal resistance of the individual laminas. Statement II: Heat transferred is directly proportional to the temperature gradient in each layer.

Statement I: A wire of uniform cross-section and uniform resistivity is connected across an ideal cell. Now the length of the wire is doubled keeping volume of the wire constant. The drift velocity of electrons after stretching the wire becomes one-fouth of what it was before stretching the wire. Statement II: If a wire (of uniform resistivity and uniform cross section) of length l_0 is stretched to length nl_0 , then its resistance becomes n^2 times of what it was before stretching the wire (the volume of wire is kept constant in stretching process). Further at constant potential difference, current is inversely proportional to resistance. Finally, drift velocity of free electron is directly proportional to current and inversely proportional to cross-sectional area of current carrying wire.

In a mercury-glass thermometer the cross-section of the capillary portion is A_(0) and the volume of the bulb is V_(0) at 273K . If alpha and gamma are the coefficients of linear and cubical expansion coefficients of glass and mercury respectively then length of mercury in the capillary at temperature t^(@)C is (Ignore the increase in cross-sectional area of capillary)

Statement I: In free space a uniform spherical planet of mass M has a smooth narrow tunnel along its diameter. This planet and another superdense small particle of mass M start approaching towards each other from rest under action of their gravitational forces. When the particle passes through the centre of the planet, sum of kinetic energies of both the bodies is maximum. Statement II: When the resultant of all forces acting on a particle or a particle like object (initially at rest) is constant in direction, the kinetic energy of the particle keeps on increasing.

A thin copper rod of uniform cross section A square metres and of length L metres has a spherical metal sphere of radius r metre at tis one end symmetrically attached to the copper rod. The thermal conductivity of copper is K and the emissivity of the spherical surface of the sphere is epsi .The free end of the copper rod is maintained at the temperature T kelving by supplying thermal energy from a P watt source. Steady state conditions are allowed ot be established while the rod is properly insulated aginst heat loss from its lateral surface. Surroundings are at 0^@C Stefan's constant =sigma W//m^(2)K^(4) . If the metal sphere attached at the end of the copper rod is made of brass, whose thermal conductivity is K_b lt K , then which of the following statements is true?

Read the given statements and select the correct ones. (i)Autonomic neural system transmits impulses from the CNS to the voluntary organs and striated muscles of the body. (ii)Unmyelinated nerve fibres do not have Schwann cells which form the myelin sheath. (iii)Axonal membrane of a neuron while not conducting any impulse is comparatively more permeable to potassium ions (K^+) than to sodium ions (Na^+) (iv)A synapse is formed by the membranes of presynaptic neuron and a post synaptic neuron.
