Slope ( = tan ϴ), displacement time graph shows velocity: V₁/V₂ = tan ϴ₁ / tan ϴ₂ = tan 30°/ tan 60° = 1/√3 / √3 = 1/3 = 1:3

% Change = Δ p/p x 100 = 4p – p/p x 100 = 300 % (2 m . 2v = 4 mv = 4 p)

The liquid having low boiling point will evaporates first and then after condensation, collected in beaker whereas the residue left in flask is a liquid which have high boiling point.

The Newton’s second law of motion, can be expressed as – Force ∝ change in momentum/time taken or, F ∝ mv-mu/t or, F ∝ m(v-u)/t or, F ∝ ma or, F = kma [where k is constant] But the value ...

Given, mass m = 2 kg, velocity v = 4 ms⁻¹. As the object is moving with a constant velocity i.e., 4 ms⁻¹. So, the acceleration of the object is zero i.e., a = 0 and according to the property ...
