As a truck rounds a curve, a box in the bed of the truck slides to the side farthest from the center of the curve. this movement of the box is a result of ? gravity inertia centripetal force centrifugal force

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

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.
