17- Soient deux conducteurs ohmiques de résistances R1 =10 22
et R2=2012.
Calculez la résistance du conducteur
ohmique équivalent lorsque ces deux
conducteurs sont groupés;
a- en série
b- en dérivation.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
