Acar is traveling at a speed of 95 mi/h. if there are 0.62137 miles (mi) in a kilometer,
what is the speed of the car in m/s?

42 m/s

Explanation:

To we convert units for speed we can use dimensional analysis. First thing we do is seperate the measurement into a fraction. After this we can multiply by 1km over 0.62137 miles. We do this so that the miles cancel out.

× =

After this we can use a conversion factor and divide by 3.6.

÷ 3.6 = 42 m/s

The particles can arrange in different ways

Explanation:

Physical change is a change in state or phase which does not produce a new substance.  Physical changes include changing the state of a pure substance between solid, liquid, and gas phases of matter, like melting, freezing, vaporization, condensation, sublimation. The following can occur in a physical change:  The particles can arrange in different ways. Correct The particles can arrange in different ways. All other options are characteristics of a chemical change which results in new substance.
