What answer should be reported, with the correct number of
significant figures, for the following calculation? (249.362 +
41)/63.498 Please explain the significant figures portion.
Please, answer below questions:
Remember units. Use the correct number of significant
figures.
1. A laser produces a beam of light with a
radius of 1.7 mm. Its energy density is 9.17 10-7 J/m3 . a) What is
its power? b) What is the force of its radiation pressure?
2. As light goes from air to an unknown liquid,
an incident angle of 20.0° becomes a refracted angle of 13.1°. If
light goes from the unknown liquid to air, what...

Please answer these questions:
1) What determines the number of significant figures in an
experimental measurement?
2) How do we find experimental uncertainty in measurement?Why is
this important?
3) What is easier to measure, the diameter or the radius of a ball,
and why?
