Definitely D. The brakes on a bike rub against the wheel. Not sure about the others.
Answer:
The ocean is 6485.6m deep when measured from the vessel
Explanation:
v=1474m/s
t=8.88s
let d represent distance from the vessel to the ocean bottom.
an echo travels a distance equivalent to 2d, that is to and fro after it reflects from the obstacle.


d= 6485.6m
Answer:
The net force is 500N downwards
Explanation:
When Haley is trying to pull an object upward. The below forces are acting on the object.
Fp = 5500N
Fg = 6000N
because the force of gravity is more than the force of the pull.
Fnet = Fg - Fp = 6000N - 5500N = 500N
And, the direction of the resultant force is the direction of the larger force.
Pretty sure it is clockwise if I am not mistaken
