A 2.0 kilogram cart is lifted up by 0.40 meters to the top of a ramp. What is the amount of potential energy gained by the cart?

the force required to move the cart is divided by three or 33.33 n.

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.

measure their densities same density, same sub

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
