A cyclist is travelling at 4.0 m/s. She speeds up to 16 m/s in a time of 5.6 s. Calculate her acceleration.

acceleration:  2.14 m/s²

Explanation:

          acceleration =  (final velocity - initial velocity ) ÷ time taken

Here the final velocity is 16 m/s, initial velocity is 4 m/s, time taken is 5.6 s

acceleration = ( 16 - 4 ) ÷ 5.6

                     → 12 ÷  5.6

                     → m/s² or 2.14 m/s²

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.
