Answer» Answer: the extension is become 6cm long Explanation: (normal spring size)3cm + 2 newton = 4.5 cm then SUBTRACT 4.5 cm to 3 cm = 1.5 cm 2 newton is equal to 1.5 cm added in spring so 4 N = twice of 2 N = 1.5cm + 1.5cm = 3 3cm + 3 cm = 6 cm

Answer»

Answer:

the extension is become 6cm long

Explanation:

(normal spring size)3cm + 2 newton = 4.5 cm

then SUBTRACT 4.5 cm to 3 cm = 1.5 cm

2 newton is equal to 1.5 cm added in spring

so 4 N = twice of 2 N = 1.5cm + 1.5cm = 3

3cm + 3 cm = 6 cm
