EXPLAINING : The raw egg keeps spinning after you touch it briefly because the liquid egg inside remains in motion, it's inertia is greater than that of the solid interior of the hardboiled egg. An object's momentum is its resistance to changing its state of motion; roughly "how hard it is to stop".
Answer : object's momentum

Answer:
For pipes that play low-frequency notes, the advantage of using a tube which is open at both ends is that it produces sound whose wavelength is just twice the length of the tube but a tube which is open at one end and closed at the other produces sound with a wavelength equal to four times the length of the tube.
Therefore the tube which is open at both ends more suitable for low frequency note.

Answer:
water
Explanation:
In 1923, Bronsted and Lowry independently proposed a theory to explain the acid-base behavior of substances, in which acids are proton donors while bases are proton acceptors.
NH3+H2O⇌NH+4+OH−
Water acts as an acid, yielding a proton to ammonia, which in turn acts as a base. Water becomes its conjugate base; the hydroxide ion. While ammonia becomes its conjugated acid; the ammonium ion.
On the other hand, when water reacts with nitric acid, it is water that accepts protons to form the hydronium ion and nitric acid that donates them. In this case the water acts as the Brønsted-Lowry base.
Answer:
Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.
Explanation:
Given:
Speed of sound in air = 320 m/s
Speed of sound in water = 1600 m/s
Time taken to reach certain distance in air = 2.5 sec
a.
We have to find the distance traveled by sound in air.
Distance = Product of speed and time.
⇒
⇒
⇒ meters.
b.
Now we have to find how much time the sound will take to travel in water.
⇒ Time = Ratio of distance and speed
⇒
⇒ <em> ...distance = 800 m and speed = 1600 m/s</em>
⇒
⇒ seconds.
Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.
