qual charges, one at rest, the other having a velocity of 104 m/s, are released in a uniform magnetic field. Which charge has the largest force exerted on it by the magnetic field?

The correct option is D

Explanation:

From the question we are told that

    The speed of the first charge is  

This is because it is at rest

     The speed of the second charge is  

Generally the force exerted by a magnetic field on a charge is mathematically represented as

Now looking at this above equation we can see that can only be maximum at   and this only obtained when the direction of the charge (i.e its velocity  ) is perpendicular to the direction of the magnetic field

so the correct option for this question is D

god i hope this !

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
