Forces that act in equal and opposite directions on an object
Akimi4 [234]
These are known as balanced forces because they will not change the motion of the object, and it will remain at rest unless forces become unbalanced- meaning they would be unequal and not opposing.

Please help!!!
iVinArrow [24]

A).  Her distance traveled was (700m + 500m) = <em>1,200 meters</em>

B).  Her displacement was (700m north + 500m south) = <em>200 meters north</em>

C).  Her average speed = (distance covered) / (time to cover the distance)

Speed = (1,200 meters) / (15 seconds)

<em>Speed = 80 meters/second</em>

(Layne is an incredible walker !  That's about 179 miles per hour.)

(She walks 700m in 10 seconds.  Usain Bolt runs only 100m in 10 seconds.)

D).  Her averge velocity = (displacement) / (time)

Velocity = (200 meters north) / (15 seconds)

<em>Velocity = (13 and 1/3) m/s north</em>

(This is only about 33% faster than Usain Bolt, if he went straight instead of doubling back, and if he could keep it up for 200 meters instead of only 100 meters.)

How did scientists determine the age of the ocean floor
Umnica [9.8K]

the layers of rocks, the ancient treasures that are at the bottom of the sea, how old the coral is. But I don't think they determined how old it is, how would the dinosaurs that lived in water swim or any drink water. I don't know if this helps but hopefully it does. Also scientist have made advanced tech that could help with the age determination of the ocean floor.
