Express (a) 50 km/hour mm/s.
(b) 60 litres in m3 cube if 1 litre = 0.001m3.
you can always multiply by 1 without changing anything
50km/hr * 10^6mm/km * 1hr/3600s = 13888.8mm/s
60L * .001m^3/L = .06m^3
To convert from kilometers per hour to millimeters per second, we need to convert each unit one step at a time. Here's how you can do it:
(a) To convert from km/h to mm/s, you need to convert km to mm and hours to seconds.
1 km = 1000 m (since there are 1000 meters in a kilometer)
1 m = 1000 mm (since there are 1000 millimeters in a meter)
1 hour = 3600 seconds (since there are 3600 seconds in an hour)
Therefore, to convert 50 km/h to mm/s, you would multiply by the conversion factors:
50 km/h * (1000 m/km) * (1000 mm/m) * (1 h/3600 s)
Simplifying this expression:
50 * 1000 * 1000 / 3600 = 13888.88 mm/s (rounded off to 2 decimal places)
So, 50 km/h is approximately equal to 13888.88 mm/s.
(b) To convert from liters to cubic meters, we need to use the given conversion factor:
1 liter = 0.001 cubic meters
To convert 60 liters to cubic meters, you would multiply by the conversion factor:
60 liters * 0.001 m^3/liter
Simplifying this expression:
60 * 0.001 = 0.06 m^3
So, 60 liters is equal to 0.06 cubic meters.
