Water at 4^oC (for solids and liquids), Hydrogen (H₂) [ for gases]

19. The specific gravity of an empty bottle weighs ‘A’ gram. While, ‘B’ when it (bottle) filled with water and so ‘C’ grams when filled a liquid than the relative density of the liquid is

RD of the liquid = B-A/C-A [ dimensionless quantity and no units]

20. The density of all substances decreases with rising in temperature, why?

Because temperature is proportional to volume and volume is the inversely proportional density.

21.The decrease in density with the rise in temperature in the matter are

Highest for gases, then for liquids, and the lowest for solids.

22. Why convection currents are set in a gas or a liquid?

33. What is rotatory motion?

The motion of a body in which (all particles on it) moves along a circular path w.r.t fixed axis. As a result, it called rotatory motion (e.g., merry-go-round).

34. If a body undergoes both translatory motions and rotatory motions then the body called in

Rolling motion (e.g., the motion of a bicycle wheel)

How Does a Popular Pendulum Help People Judge Sure?

35. If the motion of the body repeats itself at a regular interval of time, then the body in

Periodic motion (e.g., the motion of the earth around the sun)

Oscillatory Motion

The to and fro motion of objects along the same path

36. The to and fro motion of an object along the same path termed as

Oscillatory motion (e.g., the motion of a clock pendulum)

37. Sometimes it seen a body maintain two or more kinds of motions at the same time then the body is in

Many motions (e.g., drawing water from the well-the bucket is in upwards translatory motion. But the pully is in rotatory motion)

38. The position of bob in a simple pendulum when it is at rest called

Equilibrium position (or mean position) [in this position string is in vertical]

39. The pendulum’s bob position where the greatest distance from the mean position travelled is in

Extreme positions

40. The largest displacement of the bob from its mean position termed as

Amplitude of pendulum

41. The time spared by the bob of a pendulum (or, watch pendulum) to complete one oscillation called

44. The time-period (T) of a simple pendulum depends on its

The numbers of oscillations made by swinging pendulum

45. The pendulum having a time-period of 2s is called

Second pendulum

FAQs

What are the units of measure?

The standard of measurement used while calculating the stock of any item. This called the Units of Measure. These are expressed in measurements. Examples of units of measurement are feet, pounds, and gallons.

Mention some basic units of measurement?

Following are some SI base units, which have special importance:

For measuring length – meter (m)
To calculate time – second(s)
To measure the amount of substance – mole (mol)
Thus, to know the magnitude of electric current – ampere (A)
Temperature – Kelvin (K)
Luminous Intensity – Candela (cd) and for
Mass – Kilograms (kg)

What are the benefits of using SI units?

SI is the System of International Units. And the biggest advantage is that one unit is used for each measurement. As a result, no need to change from one unit to another. Thus, it is convenient for everyone.
