Why can we hear sounds better in air than underwater?
Explain why we can hear sounds better in air than we can underwater.
comparison to liquids, so when a sound travels through air is vibrates the air very easily Without much distortion (changes).
So, although sound travels better in water, it is harder to hear properly..
What are things that move slow?
A very slow-moving shark. Human: Compared to other mammals, humans are very slow movers and have a top speed of almost 28 miles per hour….Here’s a visual list of things that are slow:Tectonic Plate.Tortoise.Sloth.Turtle.Loris.Giant Galapagos Tortoise.Sea Anemone.Jellyfish.More items…•
Why do heavier things move slower?
INERTIA. … The greater the weight (or mass) of an object, the more inertia it has. Heavy objects are harder to move than light ones because they have more inertia. Inertia also makes it harder to stop heavy things once they are moving.
Would a giant move slower?
A giant has long arms and legs. It’s limbs will have to move on a slower period to feel real. Massive objects also seem to just move slower because of the scale involved. We see this effect with mechanical objects.
Why does light travel slower in glass?
The “phase velocity” of light is slowed because it interacts with atoms of the glass as it makes its way through it. … Because the refractive index of glass is more than the air or vacuum . when the rays of light comes from the air or vacuum and enters into the glass then it bands from its original direction.
Is sound louder in water?
Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster. This should make the sound appear louder.
What helps us to decide which body is moving faster than the other?
Answer. We can decide whether an object is moving faster than the object by calculating it’s speed with the formula Speed = Distance/Time.
What are things that are fast?
From cheetahs to airplanes: 11 of the fastest things out thereLand animal: the cheetah. … Air animal: the peregrine falcon. … Sea animal: the black marlin. … Automotive: Bugatti Veyron EB 16.4. … Airplane: Lockheed SR-71 Blackbird. … Train: JR-Maglev. … Rapper: Twista. … Painter: Morris Katz.More items…•
How do you decide which object moves faster or slower?
In simple words, the distance covered by an object in a fixed interval of time helps you know whether the object is moving fast or slow. The object that shows fast motion is said to have a higher speed while the one with slow motion is said to have a slow speed.
Why do you move slower in water?
Objects move slower in water than air because of the increased density of the medium and the water molecules are tightly packed as compared to those in air which inturn increases the surface tension of every layer of water the object penetrates, thereby reducing the kinetic energy of the object to some more extent than …
Why does a feather fall slower than a brick?
Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls. … Air resistance causes the feather to fall more slowly.
Do Heavier Things move faster?
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
