4) PRACTICE SOME CONVERSION PROBLEM

Answer 1

This question is about metric prefixes, scientific notation, and unit conversions in the metric system.

Step-by-step explanation:

Metric Prefixes and Scientific Notation

The metric system uses prefixes to represent different sizes of units. The most common metric prefixes are kilo, centi, and milli. Scientific notation is a way to express large or small numbers using powers of ten.

(a) 89 Tm = 89 x 10^12 m

(b) 89 pm = 89 x 10^-12 m

(c) 711 mm = 711 x 10^-3 m

(d) 0.45 μm = 0.45 x 10^-6 m

Metric Prefixes and Unit Conversions

To convert between different metric units, you can use the metric prefixes. Here are some examples:

(a) 7.59 x 10^7 m = 759 km

(b) 0.0074 m = 7.4 cm

(c) 8.8 x 10^-11 m = 88 pm

(d) 1.63 x 10^13 m = 16.3 Mm
