A negatively charged particle is moving through uniform fields E and B, which are directed in the positive x and positive y directions, respectively. If there is no resultant force on the particle, then its velocity is in the

the results is a decrease in air temperature with an increase of altitude.

explanation:

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.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

i think the answer is a and b

i wish you luck
