(a)
Interpretation:
The round off value should be identified given the significant figures.
Concept Introduction:
Significant figures: The term significant figures refer to the number of important single digits in the co-efficient of an expression in scientific notation (for example 0 to 9 inclusive).
In other words precision of measurements, the value recorded should use all the digits known with certainty, plus one additional estimated digit that is usually considered uncertain by plus or minus one it should be written as
The numbers that follow the following rules are considered to be significant.
- 1. All non-zero numbers are significant.
- 2. The zero that present between the two significant digits are also significant.
- 3. The zero that comes after the decimal point is considered as significant.
(b)
Interpretation:
The conversion should be identified from standard notation into scientific notation.
Concept Introduction:
Scientific notation: This method to expressing numbers in terms of a decimal number between 1 and 10 multiplexed by a power of 10 it is called scientific notation. For example

- Does a Snickers™ candy bar (65 g, 1360 kJ) pro-vide enough energy to climb from Zermatt (elevation 1660m) to the top of the Matterhorn (4478 m, Figure Q2–3),or might you need to stop at HÖrnli Hut (3260 m) to eatanother one? Imagine that you and your gear have a massof 75 kg, and that all of your work is done against gravity(that is, you are just climbing straight up). Remember fromyour introductory physics course thatwork (J) = mass (kg) × g (m/sec2) × height gained (m)where g is acceleration due to gravity (9.8 m/sec2).
