A car travels at a speed of 20.5 miles per hour. What is this speed in Km/sec and inches/min

0.00916432 km/s

21648 inches/minute

Explanation:

1 kilometre / second =

2236.936 miles per hour

20.5/2236.9=0.00916432km/s

1 mile per hour =

1056 inches / minute

20.5×1056=21648 inches/minute

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
