There are two types of mechanical waves:
longitudinal waves : Their displacement is in a direction perpendicular to the vibrations of the wave forming crests and troughs.
Transverse waves : They have the vibrations in the direction of the wave forming compressions and rarefactions.
Explanation:
First of all we calculate the volume which is 20m×10m×8m= 1600m^3 and then multiply the density by the volume to get the mass which will equal to 99200kg therefore the weight will be
<em><u>Weight</u></em>
mass × acceleration due to gravity
=99200kg × 10m^s^2
=992000N
The ultraviolet catastrophe was the prediction of late 19th century/early 20th century classical physics that an ideal black body (also blackbody) at thermal equilibrium will emit radiation in all frequency ranges, emitting more energy as the frequency increases.
Answer:
i would say a) two playlists
hope this helps!
Explanation:
It’s around the g force so it’s gonna be around 54 km/h
