Two cars are each traveling at 72 km/h one car is traveling northeast, and the other is traveling south the two cars have different

Velocities

Explanation:

Given that, two cars are each traveling at 72 km/h one car is traveling northeast, and the other is traveling south. Since, both objects are moving with same speeds but the direction of both cars is opposite. In this case, both cars will have different velocities. Velocity of an object is vector quantity i.e. it will have same magnitude but different velocity.

Hence, two cars have different velocities.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
