When a 8.65 kg mass is placed on top of a vertical spring, the spring compresses 3.56 cm. Find the force constant of the spring.

the amount of current in the coil

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
