A car traveling at 35m/s appliance its brakes 10 seconds later it has a velocity of 5m/s what is the acceleration of the car

a = -3 m/s^2

Explanation:

Vi = 35 m/s

Vf = 5 m/s

t = 10 s

Plug those values into the following equation:

Vf = Vi + at

5 = 35 + 10a

---> a = -3 m/s^2

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.
