1 answer:

6 0

Answer:

Graphite is actually diamagnetic. Pyrolytic graphite is commonly used with neodymium magnet cube arrays to float above it due to the graphite becoming a magnet with the same polarity as the field facing it so it repels.

Two equal mass carts approach each other with velocities equal in magnitude but opposite in direction. Friction can be neglected

Answer:

Explanation:

Since momentum is given by:

$\vec{p}=m.\vec{v}$

Therefore momentum is a vector quantity in the direction of velocity.

Inelastic collision is the type of collision in which the masses combine after collision and start moving in the direction of the greater momentum but here in this case we have the momentum equal and opposite in direction.

This case can be described mathematically as:

$m_1.\vec{v_1}=m_2.\vec{v_2}$
