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 ...

As we know that, the total distance covered, S = final reading of odometer – initial reading of odometer = (4460 – 4200) km = 260 km Total displacement = 0 km Total time taken, t = 4 h 20 ...

The nucleus has a two-layered covering called the nuclear membrane. The nuclear membrane contains pores that allow the transfer of material from inside the nucleus to the outside.
