Bbarometer
Cmanometer
Dmicrometer

2.) How many miliseconds (ms) are there in 3.5 seconds (s) ?

A35 ms
B350 ms
C3,500 ms
D35,000 ms

Verified Answer :

1) a
2) 1000 milliseconds = 1 second, so 1000 * 3.5= 3500 making your answer C

Answer: Best tool for measuring temperature is thermometer.

              There are 3500 miliseconds in 3.5 seconds.

Explanation:

Thermometer is a device or tool used to determine the temperature.

Thus, when Thomas wants to measure the temperature change that occurs when sodium hydroxide is dissolved in water then the best tool for this purpose is thermometer.

It is known that there are 1000 miliseconds in one second. Therefore, calculate miliseconds in 3.5 seconds as follows.

        \(3.5 second \times 1000\frac{milisecond}{second}\) = 3500 milisecond

Thus, there are 3500 ms in 3.5 seconds.
