What is the fundamental frequency of a particular medium? . a.the lowest frequency at which a standing wave is possible. b. the highest frequency at which s standing wave is possible

The correct answer is definitely A) the lowest frequency at which a standing wave is possible. I choose this option because standing can occur only at a fundamental frequency and at odd harmonics --> the lowest frequence.

Raising its temperature by

Explanation:

The specific heat capacity of a substance is defined as the amount of energy needed to raise the temperature of 1 kg of a substance by .

The specific heat capacity of a substance essentially tells us how much energy is needed to heat the substance: the larger it is, the more energy is needed. The amount of energy needed to increase the temperature of a substance is given by

where

m is the mass of the substance

Cs is the specific heat capacity

is the temperature variation of the substance
