Two grapefruits of masses 50g and 75g respectively are falling from the top of the tree simultaneously. Given that the height of the tree is 32m, calculate the time taken by the heavier fruit to hit the ground.(g=10m/s² and neglect air resistance)

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.
