Question

(5) 20 meters/second to mph. (6) 1 kilogram/meter3 to grams/cu3 IV. Angular Measurements Sometimes when we look at objects in the sky, we can't tell how far away th than being able to talk about the linear size of an object or its movemer angular size. Remember that a full circle encompasses 360°, so we can dra Earth and divide it up into degrees (and even smaller units). When we sky, or moving across the sky, we can measure its angular extent the time we will deal with angles smaller than a degree. A degree can b smaller units of measurement. There are 60 arcminutes in a degree, a arcminute. Therefore, there are 3600 arcseconds in every degree. Yo units in later labs. based We can also use angular measurements to determine linear distances, trigonometry 90° (a ahel the lengths of

Explanation / Answer

Solution:-

5) 20 meters/Second to mph=?

we know that 1m/s=2.2369mph(approx 2.24mph)

so 20 m/s=?mph

=20*2.2369=44.738 mph (approx 44.8mph)

6) 1kg/meter3 to gram/cm3

1kg=1000gm and 1 meter=100 cm

so 1kg/meter3= 1000 gram / (100)3

= 0.001 gram/cm3
