A boat crossing a 153.0 m wide river is directed so that it will cross the river as quickly as possible. The boat has a speed of

5.70 m/s in still water and the river flows uniformly at 4.90 m/s. Calculate the total distance the boat will travel to reach the opposite shore.

Answer:

201.76266192 m

Explanation:

Distance traveled in the horizontal direction = 153 m

In the vertical direction the distance traveled

\dfrac{4.9\times 153}{5.7}=131.526315789\ m

Total distance from pythagoras theorem

d=\sqrt{153^2+(\dfrac{4.9\times 153}{5.7})^2}\\\Rightarrow d=201.76266192\ m

The total distance the boat will travel to reach the opposite shore is 201.76266192 m

Answer:

very small solid particles called interstellar dust.

Explanation:

In the space between the stars there is gas and dust, which represent at least 20% of the mass of our galaxy. In the Milky Way it is considered that there is a gas density of approximately 0.2 to 0.5 atoms / cm3 in the surroundings of the Sun; with respect to the dust an average of 1 g / cm3 is estimated.

Gas is about atoms and molecules, mainly hydrogen; In order of abundance, helium, carbon, oxygen, nitrogen and iron follow. On the other hand, the dust is tiny particles, generally smaller than 10 microns; the dust does not shine and therefore it is only distinguished when it is projected on bright regions (nebulae or clusters).

Interstellar matter is mainly concentrated towards the plane of the galaxy, in the strip corresponding to the Milky Way; there you can see bright nebulas of diffuse character called nebulas. These nebulae are classified according to three types: (a) bright or emission nebulae, (b) reflection nebulae and (c) planetary nebulae.

Hydrogen appears both ionized and neutral; The bright nebulae are composed of ionized hydrogen and other ionized elements. Non-ionized (neutral) hydrogen is found in the spiral arms of the Milky Way and can be detected through radio waves.

medium

Explanation:

<em>A sound </em><em>medium</em><em> is defined as channel through which sound can travel or be transmitted. </em>

Sound medium could be in the form gases, liquids, solids or plasmas. Space is made up of vacuum and therefore, has no medium within it. Hence, space cannot transmit sound in any form or allows sound to travel through it.
