A hypothesis is an educated guess. It's your own opinion!
Explanation:
Average speed = distance / time
|v| = (7 km + 2 km) / (2 hr + 1 hr)
|v| = 3 km/hr
Average velocity = displacement / time
v = (7 km east + 2 km east) / (2 hr + 1 hr)
v = 3 km/hr east
The masses of the object and the planet it's on, and the distance between their centers.
Around the nucleus or in the shell of the atom. Hope this makes sense.
