Q. 1.16
What is the weight in newtons of an object that has a mass of: (a) 10 kg, (b) 0.5 g, and (c) 4.50 Mg? Express the result to three significant figures. Use an appropriate prefix.
Step-by-Step
Verified Solution
a) W=\left(9.81 m / s ^2\right)(10 kg )=98.1 N
b) W=\left(9.81 m / s ^2\right)(0.5 g )\left(10^{-3} kg / g \right)=4.90 mN
c) W=\left(9.81 m / s ^2\right)(4.5 Mg )\left(10^3 kg / Mg \right)=44.1 kN
