A horse has been clocked at 90 km/hr. What is its speed in centimeters per second? USE UNIT CANCELLATIONS AND SHOW ALL WORK.

2502 cm/s

Explanation:

In conversions from one unit to another,we always use a conversion factor. A conversion factor is a number used to change one set of units to another, by multiplying or dividing.  The conversion factor in changing km/hr to cm/s is:

1 km/hr = 27.8 cm/s.

Hence 90 km/hr = 90 * 27.8 = 2502 cm/s

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
