Question

Represent 8953 ms with Sl units having an appropriate prefix Express your answer to four significant figures and include the appropriate units. PÅ ROS? 8953 ms = 8.953 . 10 ms

Answer 1

Answer:

8.953 s

Explanation:

Here a time of 8953 ms is given.

Some of the prefixes of the SI units are

mili = 10⁻³

micro = 10⁻⁶

nano = 10⁻⁹

kilo = 10³

Mega = 10⁶

Each prefix increases or decreases by a factor of 10³

The number is 8953.0

Here, the only solution where the number of significant figures is mili.  If any other prefix is chosen then the significant figures will increase.

$1 milisecond = 1000 second$

$1\ second=\frac{1}{1000}\ milisecond$

$\\\Rightarrow 8953\ milisecond=\frac{8953}{1000}\ second\\ =8.953\ second$

So, 8953 ms = 8.953 s
