# What frequency is heard by the moth?

## What frequency is heard by the moth?

The researchers determined that the moth, which is brown and feeds on honeycomb, is capable of sensing sound frequencies of up to 300 kilohertz. Humans can hear sounds up to 20 kilohertz. The figure drops to about 15 kilohertz in adults.

## What is a 0.12 kg ball moving at 6m s when it is hit by a bat?

Final answer: The magnitude of the change in momentum of a 0.12-kg ball that is hit by a bat and reverses direction from 6 m/s to 14 m/s, is 2.4 kg m/s.

## How high can bats hear?

Species Approximate Range (Hz)
bat 2,000-110,000
beluga whale 1,000-123,000
elephant 16-12,000
porpoise 75-150,000

## Can moths hear us?

Most of the moths heard noises as high as 300 kHz, giving them the most sensitive ears in the insect world, the scientists report online today in Biology Letters. In comparison, humans’ ears give up by 23 kHz or so and cats top out at about 64 kHz; the highest known bat calls are about 212 kHz.

## What is the velocity of the 3 kg ball after the collision?

The velocity of the 3 kg ball is 4 m/s after the collision.

## What is the KE of a 3kg ball that is rolling at 2m s?

KE= ½ m v2 = ½ (3kg) (2 m/s)2 = 6 Joules 8.

## What do bats smell?

Their unique fur coloring helps to camouflage them and keep them safe by making them appear as pine cones, dried leaves or even tree bark. These insect-eating bats are among the most beautiful in the US but have the unfortunate (albeit very faint) odor of fish combined with urine.

## Can dogs hear bats?

Science Behind Dogs Hearing Bats Scientifically, bats use sonar to communicate and to fly safely, but they make a variety of sounds. Online, the general consensus among dog owners is that dogs probably can hear some of the sounds bats make, just like humans can. Dogs can typically hear sounds between 67-45,000 Hz.

## How do dogs hear?

After being funnelled into the ear by the pinna, sound waves travel through the ear canal and vibrate through the eardrum. The vibrations are then amplified by tiny bones through to the inner ear. In dogs, these bones are shaped to amplify sounds better than in humans, giving dogs greater sound sensitivity.

## What sounds do moths make?

Typically, anti-bat sounds are produced by structures called tymbals, small areas of thin cuticle on a moth’s body, which are connected to a muscle. As the muscle contracts, the tymbal buckles and produces a click, then as the muscle relaxes, the tymbal snaps back to its resting state and produces another click.
