Question # 1

What dose the word "micro" signify in the words "micro wave oven ?

  • Ans 1: Micro means very small. Micro waves have the shortest wavelength of all the shortest wavelengths of all the radio waves, therefore, these are known as microwaves. Now like all electromagnetic waves the microwaves produces heating effect when their energy is absorbed. It is because, due to shorter wave length the micro waves posses high frequency and maximum energy.

Question # 1

Define Base, Derived, supplementary, Units ?

  • Ans 1: Base Units:The units of base quantities are known as base unit.
    Base quantity: Symbol
    Length l
    Mass M
    Time t
    Electric current I
    Temperature T
    Derived Quantity:The unit of derived quantities are known as derived units. The derived units can be derived from base unit and supplementary units
    Supplementary Units:The general conference on weight and measures has not yet classified certain units of the SI under either base units or derived units such SI Units are called supplementary units This class contains only two units of purely geometrical quantities which are place angle and the said angle.
    1. Radian :It is the unit of plane angle. One radian represents a plane angle subtended at the center of a circle by on are of length equal to radius of the circle.
    2. Steradian:Steradian is the unit for a solid angle in a three dimensional space steradian is defined as "the solid angle subtended at the center of a sphere by an area of its surface equal to the square of the radius of that sphere"

Question # 1

Give the drawbacks to use the period of pendulum as a time standard.

  • Ans 1:
    The value of time periods of a simple pendulum depends upon its length and gravitational acceleration. So, the following drawbacks will be observed.
    • The value of g varies with altitudes
    • Length of the pendulum varies due to the increase or decrease in temperature .
    • Air resistance will affect the time period.

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.
