pshichka [43]3 years ago
6 0

Answer:

A)an object whose electrons can be aligned in the same direction

Explanation:

Those materials produce magnetic field is known as magnet materials.A magnet is a object whose electrons are aligned in the same direction.

All ferromagnetic materials are magnetic materials. The examples magnetic materials are Co (Cobalt),Ni (Nickel) etc.We know that magnetic filed are produce by the current.

Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive b
ivanzaharov [21]

Answer:

Explanation:

a ) Conservation of momentum is followed

m₁ v₁  = m₂ v₂

3m x 2 = m  v

v = 6 m/s

Total kinetic energy

= 1/2 x .35 x 6 ² + 1/2 x 1.05 x 2 ²

= 8.4 J

This energy must be stored as elastic energy in the spring which was released as kinetic energy on burning the cord.

Yes , the conservation of momentum will be followed  in the bursting apart process. Only internal forces have been involved in the process. Two equal and opposite internal forces are created by spring which creates motion and generates kinetic energy.
