Answer the following questions about the two standard units of force.
a. (i) Define one newton in terms of the acceleration it produces in a given mass.
b. (ii) Define one dyne in similar words.
c. (iii) Explain why the numerical value of a given force is 105 times larger when expressed in dynes rather than in newtons.
d. (iv) A student notes a force reading of 2.5×104 dynes on a spring balance. Without actually performing the numerical calculation, describe step-by-step how you would convert this reading into the SI unit.
