Answer:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

80 (km / hour) * (1,000 meters/ km) * (1 hour/ 60 minutes) * (1 minute / 60 seconds) = 22.2 meters / second
Answer:
a. You should use the thin cooking twine.
Explanation:
The velocity of wave on a rope is:
(1)
with T the tension and μ the linear density of the rope that is defined as , so (1) is:
with M the mass and L the length
Note that if L and T remain constant for bigger M velocity is going to be smaller and vice versa. So, we should chose the lighter rope that is the thin cooking twine to have the fastest wave speed.
Answer:
Their working speed = 5 km/ hour and 3 km/ hour
Explanation:
Let their speeds be x and y
2 ( x+y) =16
x+y = 8 .....................(A)
Assuming x is > y
8x- 8y = 16
x- y = 2 ................(B)
(A) + (B) 2x = 10
x = 5 km/ hour y = 3 km/ hour
Answer:
The second answer from the top, no the energy in the wave pushed the water particles from above the earthquake in the opposite direction.
Explanation:
I believe this is the correct answer. Hope you do well
