Question # 1

Differentiate between the following? (a) Light year and year

Ans 1:
1. Light Year:Light year is the unit of distance. It is defined as, " the distance travelled by light in vacuum in one year."
2. Year:Year is the unit of time. It is defined as the time interval in which the earth completes one revolution around the sun"
1 Year = 365.25 days
and
1 year = 365.25*24*3600 sec
1 year = 31557600 sec

Question # 1

Discuss the conventions for using SI units?

Ans 1: The various conventions for using SI are given below.
1. Full name of the unit does not begin with a capital letter even if named after a scientist.
2. symbol of unit name after scientist has initial capital latter for for example N for newton Pa for pascal H3 for hertz etc
3. The prefixes is written before an adjacent to the unit
4. The combination of units is written each with one space a part For example , Torque =55 N m
5. Double, triple etc prefixes are not allowed
6. When a multiple of base unit is raised to a power. The power applies to the whole multiple and not just the base unit
7. Before substituting values in the formula to calculate the final result make sure that all the included physical quantities are expressed in their SI units.
