Document Summary

For hegel, language, if it is simply private opinion, then it is random, idiosyncratic, not really evolved. Language fully comes into its own is language when it is universal and public, when it articulates universal concepts, when it reveals reality in an objective manner. Kierkegaard is critical of this (and nietzsche as well. ) Kierkegaard does not suggest that abraham disregard the universal completely. Abraham was in the universal (not a moral nihilist. ) Abraham = the absolute who stands in absolute relation with the absolute. This is an absolute relation because it is not a mediated relation, it is immediate. This means that he stands before his god in a way that is not mediated by the universal. This relation is not one that can be grasped conceptually, grasped by, say, ethics. His divine commands is not one that can be grasped conceptually either. In his view, the absolute relation established transcends even beyond divine command ethics.

A moth of length 1.0 cm is flying about 1.0 m from a bat when the bat emits a sound wave at 80.0 kHz. The temperature of the air is about 10.0 C. To sense the presence of the moth using echolocation, the bat must emit a sound with a wavelength equal to or less than the length of the insect.

where the ratio of heat capacities ( 1.4 for air), T is the absolute temperature in kelvins (which is equal to the Celsius temperature plus 273.15 C), is the molar mass of the gas (for air, the average molar mass is M=28.8*10^-3 kg/mol), and R is the universal gas constant (R=8.314J*mol^-1*K^-1).

(a) Find the wavelength of the 80.0-kHz wave emitted by the bat.

(b) How long after the bat emits the wave will it hear the echo from the moth?

A moth of length 1.0 cm is flying about 1.0 m from a bat when the bat emits a sound wave at 80.0 kHz. The temperature of the air is about 10.0∘C. To sense the presence of the moth using echolocation, the bat must emit a sound with a wavelength equal to or less than the length of the insect. The speed of sound that propagates in an ideal gas is given by v= sqrt (γRTM), where γ is the ratio of heat capacities (γ=1.4 for air), T is the absolute temperature in kelvins (which is equal to the Celsius temperature plus 273.15∘C), M is the molar mass of the gas (for air, the average molar mass is M=28.8×10−3kg/mol), and R is the universal gas constant (R=8.314J⋅mol−1⋅K−1).

Find the wavelength λ of the 80.0-kHz wave emitted by the bat.

Express your answer in millimeters.

How long after the bat emits the wave will it hear the echo from the moth?

Express your answer in milliseconds to two significant figures.
