Explanation:

The relationship between newton and dyne is based on their definitions in the SI and CGS systems of units.

1 newton is the force required to accelerate a mass of 1 kg by 1 m/s2 in the SI system.

1 N = 1 kg·m/s2

1 dyne is the force required to accelerate a mass of 1 gram by 1 cm/s2 in the CGS system.

1 dyne = 1 g·cm/s2

  • 1 kg = 1000 g
  • 1 m = 100 cm

Substitute these into the formula for newton:

1N=(1000g)⋅(100cm/s2)=100,000dyne

Final Answer:

1 newton = 105 dyne
