Question

delta l=3cm
m=150g
a) G=?
B) K=?

Answer 1

$\it \triangle \: l = 3 \: cm \\ \it m = 150 \: g \\ a) \: G = \: ? \\ b) \: K = \: ? \\ \\ a)~G=m \cdot g \\ \it G=0,15~kg \cdot 10~N/kg=1,5~N \\ \it b) G=F_{e} =K \cdot \triangle~l ==> G=K \cdot \triangle~l \\ \\ \it K=\frac{G}{\triangle~l}=\frac{1,5~N}{0,03~m}=\frac{150~N}{3~m}=50~N/m$
