The position of a particle moving along X - axis depends on time according to the equation, x = 3t2 - t
3 – 4t + 5 , where x is in meter and t is in second
Calculate velocity and acceleration at t = 0, t = 2 and t = 4seconds
b. Calculate the average velocity between t = 2 and t = 4 seconds
c. Calculate average acceleration between t =1 and t =3 seconds

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

where is the photo and the answer choices?

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
