Question

2. Place the following values in scientific notation:

2020000 m
C. 0.003020 km
9901000 m/s
d. 0.001100 mm

Answer 1

Answer: a.
`2.02*10^6\ m`

b.
`9.901*10^6\ m/s`

c.
`3.02*10 ^(-3)\ km`

d.
`1.1*10^(-3)\ mm`

Explanation:

Scientific notation is a technique to express a very big or a very small number in the product of a decimal form of number ( between 1 and 10) and powers of 10.

a.
`2,020,000 m\ = 2.02*1,000,000=2.02*10^6\ m`

b.
`9,901,000\ m/s =9.901*1000000=9.901*10^6\ m/s`

c.
`0.003020\ km=(3020)/(1000000)`

`=3.02*10 ^(-3)\ km`

d.
`0.001100\ mm=(1100)/(1000000)=(11)/(10000)`

`1.1*10^(-3)\ mm`
