Can someone tell me everything they know about mechanical waves and ASAP, please!?!?!?

A mechanical wave is a wave that is caused by matter oscillations and thus transfers energy through a medium. Although waves can travel great distances, the medium of transmission—the material—can only go so far. As a result, the oscillating material stays close to its initial equilibrium position.

Hope this helps

A roller coaster is released from the top of a track that is 57 m high. Find the roller coaster speed when it reaches ground lev

Hi there!

Assuming the track is frictionless:

$E_i = E_f\\\\PE = KE\\\\mgh = \frac{1}{2}mv^2$

Cancel out the masses and rearrange to solve for velocity:

$gh = \frac{1}{2}v^{2}\\\\v = \sqrt{2gh}\\\\$

Plug in the given height and let g = 9.8 m/s²:

$v = \sqrt{2(9.8)(57)} = \boxed{33.42 m/s}$

We can use the ideal gas equation which is expressed as PV = nRT. At a constant volume and number of moles of the gas the ratio of T and P is equal to some constant. At another set of condition, the constant is still the same. Calculations are as follows:

T1/P1 = T2/P2

P2 = T2 x P1 / T1

P2 = 273 x 340 / 713
