Slinky of mass 100g which was compressed 20cm in 10 seconds. What is the power spent on the slinky? Power=work/ time= force*displacement /time

Plz explain the force part because I can’t seem to find that

Ke=1/2(mv^2)
Gpe= meh
Epe=1/2(kx^2)

a.

explanation:

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
