Radio signals travel at a rate of 3 × 108 meters per second. how many seconds will it take for a radio signal to travel from a satellite to the surface of the earth if the satellite is orbiting at a height of 3.6 × 107 meters?

0.12 seconds

Step-by-step explanation:

speed = distance / time

so time = distance / speed

time taken =   3.6 * 10^7 / 3 * 10^8

= 1.2 * 10^-1 seconds

=  0.12 seconds answer

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

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.
