What is the mass of a rock that is accelerated to 1.4m/s^2 with a force of 350 N

F=m*a

350N=m*1.4m/s^2

m=350N/1.4m/s^2=250kg

an energy transformation flow diagram is shown

where is it ?

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.
