Answered: A Harvest Mouse Can Detect Sounds Below…

The western harvest mouse is an herbivore with a diet consisting of mainly seeds and grains from various plants. These plants include: fruits, vetch, blue grass, fescue, oats, and brome grass. [5] In preparation for autumn and winter, the western harvest mouse stores its food along runways created throughout fields that it occupies and inThe tiny harvest mouse lives in long tussocky grassland, reedbeds, hedgerows, farmland and around woodland edges. It is mainly vegetarian, eating seeds and fruits, but will also eat invertebrates. Harvest mice build a spherical nest of tightly woven grass, high-up in the tall grasses, in which the female will give birth to around six young.Harvest Mouse - Micromys minutus Taxon: Rodentia Harvest Mouse Red List Classification: GB: Near Threatened England: Least Concern Scotland: Critical Wales: Vulnerable Global: Least Concern General fact sheet (click to download) Habitat: Grassland, arable land. Description: Blunt nose, small eyes, and small hairy ears in contrast to other British species of mice and also much smallerA harvest mouse can detect sounds as quiet as -10 dB. Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby. A very gentle breeze causes a leaf 1.3 m from your head to rustle, generating a faint sound right at the limit of your ability to hear it.The harvest mouse (Micromys minutus) is a small rodent native to Europe and Asia.It is typically found in fields of cereal crops, such as wheat and oats, in reed beds and in other tall ground vegetation, such as long grass and hedgerows.It has reddish-brown fur with white underparts and a naked, highly prehensile tail, which it uses for climbing.It is the smallest European rodent; an adult may

How far is the harvest mouse from the leaf? Solution: If the leaf is generating a sound that is right at the limit of our ability to hear it, then the intensity of the sound is the same as the reference intensity I 0 = 10-12 W / m 2. We can use this to determine the power emitted from the rustling of the leaves.Constants Part A A harvest mouse can detect sounds as quiet as -10 dB. Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby. A very gentle breeze causes a leaf 2.0 m from your head to rustle, generating a faint sound right at the limit of your ability to hear it.A harvest mouse can detect sounds as quiet as -10. Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby at the entrance to its nest. A very gentle breeze causes...A harvest mouse can detect sounds below the threshold of human hearing, as quiet as -10 dB. Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby. A very gentle breeze causes a leaf 1.5 m from your head to rustle, generating a faint sound right at the limit of your ability to hear it.

Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby at the entrance to its nest. A very gentle breeze causes a leaf 2.0 from your head to rustle, generating a faint sound right at the limit of your ability to hear it. The sound of the rustling leaf is also right at the threshold of hearing of the harvestA very gentle breeze causes a leaf 1.4 m from your head to rustle, generating a faint sound right at the limit of your ability to hear it. The sound of the rustling leaf is also right at the...The western harvest mouse appears to be strictly nocturnal. The initial census of this species on the islands thought the numbers to be very small, which subsequently proved inaccurate. Appearance The western harvest mouse is a slim, medium sized mouse with adult lengths ranging from 4 ½ to 6 ½ inches in length and weight from 3 to 8 ounces.Western Harvest Mouse (Reithrodontomys megalotis)Species Code: REME Description: The Western Harvest Mouse is a slim, long-tailed mouse that has prominent, naked ears, a slender sparsely haired tail, grey above and whitish below. The coat is a reddish yellow color with some white on the underside of its belly. They can actually come in a range of colors and depending on the weather and season

Iₒ = 10 ̄ ¹² watts/m²

sound level measurements in decibels are typically referenced to a normal threshold of hearing at 1000 Hz for the human ear which can also be stated in the case of sound intensity: Iₒ

this worth has wide acceptance as a nominal same old threshold and corresponds to Zero decibels.

the sound depth I may be expressed in decibels above the standard threshold of listening to Iₒ . The expression is:

I(dB) = 10logᵢₒ(I/Iₒ)

sound energy / (4πr²) = intensity

=> P = (4πr²)Iₒ = 4π(1.4)² [10 ̄ ¹² watts/m² ] = 6.4π x 10 ̄ ¹¹ watts

=> -10 dB = 10logᵢₒ(I/Iₒ)

=> 1/10 = (I/Iₒ)

or I = Iₒ(0.1)

subsequently 6.4π x 10 ̄ ¹¹ / (4πr²) = Iₒ(0.1) = 10 ̄ ¹³

=> r² = 1.6 x 100 = 160

=> r = √160 ~= 12.65 m away

hope this is helping
