Two streamlines cannot cross each other. Why?

For a stream line flow of water following statements are given below (a) Two streamlines do not intersect each other. (b) streamlines must be straight. (c ) streamlines flow is more likely for liquids with low density and height viscosity. (d) streamlines flow is more likely for liquids with high density and low viscosity.

In the following question a statement of assertion (A) is followed by a statement of reason (R ) A: Absolute value of potential is not defined R : Two equipotential lines cannot intersect each other.

Two trains 110 m and 90 m log respectively, are trunning in opposite directions with velocities 36 km h^(-1) and 54 km h^(-1) Find the time taken by the trains to completely cross each other.

(a) An electrostaic field line is a continous curve. That is a field line cannot have sudden breaks. Why not ? (b) explain why two field lines never cross each other at any point.

Why do the electric field lines never cross each other ?

The distance between two stations is 340 km. Two trains start simultaneously from these stations on parallel tracks to cross each other. The speed of one of them is greater than that of the other by 5 km/hr. If the distance between the two trains after 2 hours of their start is 30 km, find the speed of each train.

Two straight lines are cut by a transversal. If the bisectors of a pair of co-interior angles are perpendicular to each other , prove the two straight lines are parallel to each other.

Can two streamlines in a flowing liquid cross each other ?

Both antacids and antiallergic drugs are antihistamines but they cannot replace each other. Explain why ?

Two parallel wires carrying current in the same direction attract each other while two beams of electrons travelling in the same direction repel each other. Why?
