Question

An exposure time of 0.02 seconds is equal to how many milliseconds?

a) 2 milliseconds
b) 20 milliseconds
c) 200 milliseconds
d) 2000 milliseconds

Answer 1

An exposure time of 0.02 seconds is equal to 20 milliseconds, which is obtained by multiplying the time in seconds by the conversion factor of 1,000 milliseconds per second.

Step-by-step explanation:

Converting seconds to milliseconds involves multiplying the time by 1000 since there are 1000 milliseconds in one second.

Given an exposure time of 0.02 seconds:

Step 1: Convert seconds to milliseconds using the conversion factor (1 second = 1000 milliseconds).

0.02 seconds×1000

milliseconds/second=20 milliseconds.

0.02seconds×1000milliseconds/second=20milliseconds.

Step 2: Therefore, an exposure time of 0.02 seconds is equivalent to 20 milliseconds when converted.

This conversion occurs by multiplying the time in seconds by 1000 to obtain the time in milliseconds. Thus, the correct answer is b) 20 milliseconds.
