Answer: 3750 m
Explanation:
1) You can find in the literature or internet that the speed of sound in the ocean is about 1500 m/s.
2) Then, you can find the distance travel by the sound wave in 5.0s with the equation distance = speed × time
⇒ distance = 1500m/s × 5.0 s = 7500 m
3) That sound went down until the ocean floor below and cameback all the way until the sailor heard it.
Then, the deep of the ocean fllor is half that distance:
deep = 7500m / 2 = 3750m
Answer:
This can easily be solved using the "range" formula
R = V0^2 * sin 2θ / g
V0^2 = g R / sin 2θ = 9.80 * 43 / sin 144 = 717 m^2/s^2
V0 = 26.8 m/s
N=3,1=2ml,0ms= +1/2 this is your answer
Answer:
A
Explanation:
A tendency to do nothing or to remain unchanged.
A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
An example of an energy conversion that produces an unwanted form of energy is mixing acids with water.
