Motion in Two Dimension — JEE physics STD 12 Science — Question

Assertion : We can not move even a finger without disturbing all the stars.
Reason : Every body in this universe attracts every other body with a force which is inversely proportional to the square of distance between them.

Assertion : Inertia is the property by virtue of which the body is unable to change by itself the state of rest only.
Reason : The bodies do not change their state unless acted upon by an unbalanced external force.

Assertion : The polar caps of earth are cold in comparison to equatorial plane.
Reason : The radiation absorbed by polar caps is less than the radiation absorbed by equatorial plane.

Assertion : Avogadro number is the number of atoms in one gram mole.
Reason  : Avogadro number is a dimensionless constant.

Assertion : When temperature of cold junction of a thermocouple is lowered, the value of neutral temperature of this thermocouple is raised.
Reason : When the difference of temperature of two junction is raised, more thermo e.m.f. is produced.

Assertion : The shape of a liquid drop is spherical.
Reason : The pressure inside the drop is greater than that of outside.

Assertion : Magnetism is relativistic.
Reason : When we move along with the charge so that there is no motion relative to us, we find no magnetic field associated with the charge.

Assertion : First law of thermodynamics is a restatement of the principle of conservation
Reason : Energy is fundamental quantity.

Assertion : Work done by a gas in isothermal expansion is more than the work done by the gas in the same expansion, adiabatically.
Reason : Temperature remains constant in isothermal expansion and not in adiabatic expansion.
