B. Liquids
Explanation:
Just had this question on my test.
Hope this helps :)
Let u = upward initial speed of the flea.
At the maximum height of h = 0.550 m, the vertical velocity is v = 0.
Therefore, from the formula
v² = u² - 2gh,
obtain
0 = u² - 2*(9.8 m/s²)*(0.55 m)
u² = 10.78 m²/s²
u = 3.283 m/s
Answer: The initial upward speed is 3.28 m/s (nearest thousandth)
D.sound insulators prevent from being transmitted better than elastic solids
Explanation:
The correct option from the given choices is that, sound insulators prevent sound from being transmitted better than elastic solids.
Sound is a form of wave that transmits energy from one point to another.
This wave form is a longitudinal wave in nature.
During the propagation of sound, it requires a material medium to move.
Sound insulators are special materials designed not to transmit sound energy.
Such materials cuts off sound. They are better than elastic solids in preventing sound transmission.
