Please clarify what it says in the picture. All I can say right now is to remember Newton's first law of motion; an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.
Answer:
0.932 m/h
Explanation:
Parameters given:
Distance walked by couple, D = 1.5 km
Time spent in walking, t = 60 min
To solve this we simply apply the formula for average peed:
Average Speed = total distance / total time taken
The question asks specifically to put the answer in miles per hour (m/h), hence, we need to convert the distance to miles and the time to hours:
Distance in miles:
1 km = 0.622 miles
1.5 km = 1.5 * 0.622 = 0.932 miles
Time in hours = 60 / 60 = 1 hour
Hence, the speed is:
Speed = 0.932 / 1 = 0.932 m/h
The average speed of the couple is 0.932 m/h
I think the answer is B. All planets rotate on an axis except Venues and Uranus and only Uranus has some what of a core of ice, and they for sure don’t all have rings. So I say the answer is B
Potential energy because of the positions on gravatational field
