<span>Hey there!
Awesome question=)
Siobhan can place it on a regular scale(0 gravity area), or she can use the "balance scale"
</span>
I hope this helps;)
Answer:
An electromagnet is the device through which runs current and it creates a magnetic field.
At the speed of light wich is approx 3 x 108 meters/ second
The incline is frictionless, this means we can use the conservation of energy: the initial kinetic energy of the block
is converted into gravitational potential energy
where h is the height reached by the block as it stops. By equalizing the two formulas, we get
However, this is the maximum height reached by the block. The distance along the surface of the plane is given by:
