Answer:

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.

A typical raindrop is much more massive than a mosquito and falling much faster than a mosquito flies. how does a mos quito surv
Svetradugi [14.3K]
Below are the questions:

A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic? 

<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g. 
</span>
Below are the answers:

a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s 
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>

Do the properties of adhesion, cohesion, and surface tension behave different in salt water vs fresh water
Elanso [62]

Answer:

The water has a dipole that causes it to act like a magnet, attracting other water molecules to it. Adhesion is the attractive forces that cause water to "stick" to a surface other than its own. ... The salt water has a much lower cohesion than plain water so it's attractive forces are less than plain water.
