This constriction prevents the mercury from falling back all by itself. Question 13. Explain in detail why there was a need to standardize units. All other trademarks and copyrights are the property of their respective owners. (e) A density bottle has a marking 25 mL on it. (f) When a body is immersed in a liquid, the buoyant force experienced by the body is equal to the volume of the liquid displaced by it. Describe in steps how you will use it. How are they related ? This quiz contains practice questions for Measurement Of Physical Quantities (O Level).There are explanations for some of the questions after you submit the quiz. The total surface occupied by an object is called its area. The magnitude of a quantity is expressed as numbers in its unit. The rainfall in a city on each day of a week is recorded below. (c) Volume of a cube = ________ (d) The area of an irregular lamina is measured by using a ______. Its multiples are quintal and metric tonne. , The mass of block will be: (i) A boy travels a distance of 150 m in 1 minutes. Physical Quantities, Measurements Standard and Units GK Physical quantities, Measurements standard and units general knowledge (general science gs) for UPSC, IAS, Banking, Railway SSC and other competitive examinations. Position A =3.4 cm Convert the following quantities as indicated: unit of area? Submultiple of metre = Centimetre, Question 6. You can skip questions if you would like and come (h) 36 km\ h^{-1} = _____ m\ s^{-1}. of complete squares + no. The detailed, step-by-step solutions will help you understand the concepts better and clear your confusions, if any. The standard weight are put on the right pan. (1.10) Explain how you will measure the area of (i) a square (ii) a leaf? (a) 12 inch = ft Q1) Write true or false for each statement. Answer: The mass of the block is 1. The temperature of a healthy person is 37°C. The body whose mass is to be measured is placed on the left pan. The area of a square can be calculated by using the following formula – They distinguish our numbers as measurements instead of pure numbers. (e) The thermometer used to measure the human body temperature is called the clinical thermometer. How is it related to (i) minute (ii) hour, (iii) day and (iv) year ? Name four basic measurements in our daily life. metric tonne. How many grams are in 9.0 moles of aluminum? 20 one – rupee coins are placed one above the other. Four basic measurements in our daily life are: measurement of length, measurement of mass, measurement of time, and measurement of temperature. T =36.6 C m =78kg fl =1.05 g m3. Answer: What are the S.I. Two devices used to measure the time interval of an event are. Write the correct length of the stick. Question 19. Correct the statement if it is false.
