The horizontal motion of a launched projectile affects its vertical motion.
question 6 options:
true
false

The horizontal motion of a launched projectile affects its vertical motion is false

False

Explanation:

As the trajectory falls on a plane, all the components like displacement, velocity can be classified in two components termed as horizontal and vertical component.

In a projectile motion, the horizontal components of displacement and velocity remains constant and there is change only in the vertical component of displacement and velocity.

Both components are not dependent to each other. So, the horizontal motions of a launched projectile does not affect its vertical motion.

i don't know that i agree with that but what's the question ?

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
