No, only average speed can be calculated from the distance of 90 meters and the time 3 seconds hope this helps
The answer is C. Chemistry because it is fact based and has the characteristics of a real science.
Producing a current by moving a wire through a magnetic field is called ELECTROMAGNETIC INDUCTION.
Electromagnetic induction refers to the production of an electromotive force across an electrical conductor in a changing magnetic field. The process was discovered by Micheal Faraday in 1831.
C.
because centripetal means that force only acts in the center of body in motion
It's true that mechanical waves require a medium for transmission.
