Which expression has the same dimensions as an expression yielding a value for acceleration (m/s2)? (delta v has units of m/s.) Group of answer choices delta v/(delta t)^2 (delta v)^2/delta y (delta v)^2/delta t delta v/(delta y)^2

Option (3).

Explanation:

The expression for acceleration of an object is given by :

(v-u) = the change in velocity and t is time taken

We need to write the option that has the ame dimensions as an expression yielding a value for acceleration (m/s²).

Option (1).

Option (2),

Option (3),

Hence, option (3) is same as the value of acceleration.

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.
