For a complex number written in polar form, its representation is unique as long as the argument is restricted to [0, true or false

False

Step-by-step explanation:

i = (1, π/2) = (-1, 3π/2) . . . . the same complex number written 2 ways in polar form.

The representation is unique if the "radius" is required to be positive.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
