Question

numeric answers with units
in some problems, you will be required to enter the numerical value of your answer along with the corresponding units. you can enter only numeric values (including scientific notation), as opposed to full - calculations or symbols. significant figure rules apply as below for numeric answers.
unless the instructions explicitly ask you to use a specific unit in your answer, you are free to enter any equivalent unit within the same unit system given in the problem (e.g. if the answer is 1 m, you may also enter 100 cm since 1 m = 100 cm). feel free to use the appropriate abbreviations and prefixes for units (for a list of recognized units in mastering, feel free to reference accessible units).
note that for compound units, you must use explicit multiplication between the units. for instance, newton - meter can be entered as n·m or n - m, but not nm.
part c
the momentum of an object is determined to be 7.2×10³ kg·m/s. express this quantity as provided or use any equivalent unit. (note: 1 kg = 1000 g)

Explanation:

Step1: Convert kg to g

Since \(1\ kg = 1000\ g=1\times10^{3}\ g\), then \(7.2\times 10^{9}\ kg\cdot m/s=(7.2\times 10^{9}\times10^{3})\ g\cdot m/s\).

Step2: Calculate the new value

Using the rule of exponents \(a^{m}\times a^{n}=a^{m + n}\), we have \(7.2\times 10^{9}\times10^{3}=7.2\times10^{9 + 3}=7.2\times 10^{12}\ g\cdot m/s\).

Answer:

\(7.2\times 10^{12}\ g\cdot m/s\)
