Answer:
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
Explanation:
Given ;
Average speed = 3.5cm/year
Time= 1 s
Distance = speed × time
Number of seconds in a year = 31536000 sec/year
Distance = 3.5 cm/year × 1/31536000sec/year × 1 s
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm

Answer:
124.88 km/h
34.69 m/s
Explanation:
1633.8 km = 1633800 m
13 hours 4 minutes 58 seconds = 13 + 4/60 + 58/3600 = 13.083 hours
13 hours 4 minutes 58 seconds = 13*3600 + 4*60 + 58 = 47098 seconds
So the average speed in km/h is
1633.8 / 13.083 = 124.88 km/h
The average speed in m/s is
1633800 / 47098 = 34.69 m/s
-is made mostly of hydrogen and helium.
-will eventually run out of fuel and die.
-creates energy through nuclear reactions
