A Correct answer
Explanation

1        The newton, is the force which accelerates a mass of one kilogram at the rate of one meter per second . The ratio between a CGS unit and the corresponding MKS unit is usually a power of 10. A newton accelerates a mass 1000 times greater than a dyne does, and it does so at a rate 100 times greater, so there are 100 000 = 105 dynes in a newton.
