The correct field line would be A.
Answer: energy source, path, and load
Explanation:
To solve this problem we will make a graph that allows us to understand the components acting on the body. In this way we will have the centripetal Force and the Force by gravity generating a total component. If we take both forces and get the trigonometric ratio of the tangent we would have the angle is,
Dividing both.
Therefore the angle that should the curve be banked is 15.608°
Answer:
0.0804 m / h
Explanation:
r = 1 m, dr / dt = 8 cm/h = 0.08 m/h
the volume of sphere is given by
V = 4/3 x π x r^3
Differentiate with respect to r.
dV / dr = 4 / 3 x π x 3 r^2 x dr/dt
dV/dt = 4 x π x r^2 x dr/dt
dV/dt = 4 x 3.14 x 1 x 1 x 0.08
dv/dt = 0.0804 m / h
Answer:
The air-water interface is an example of<em> </em>boundary. The <u><em>transmitted</em></u><em> </em> portion of the initial wave energy is way smaller than the <u><em>reflected</em></u><em> </em> portion. This makes the <u><em>boundary</em></u> wave hard to hear.
When both the source of the sound and your ears are located underwater, the sound is louder because the sound waves can <u><em>travel directly to your ear</em></u>.
Explanation:
The air-to-water sound wave transmission is inhibited because more of reflection than transmission of the wave occurs at the boundary. In the end, only about 30% of the sound wave eventually reaches underwater. For sound generated underwater, all the wave energy is transmitted directly to the observer. Sound wave travel faster in water than in air because, the molecules of water are more densely packed together, and hence can easily transmit their vibration to their neighboring molecules, when compared to air.
