Answer:

You missed the specific heat on water, that is 1 calorie/gram °C. This answer is, 0.12°C

Explanation:

The stayment says, that all of the energy from the pancake is transferred into the water, so we have to think that 61 calories are burned in the calorimeter with water. Let's apply on the formula.

Heat added = specific heat x mass x (tfinal - tinitial)

61 cal = 500. g .1 cal/g °C . ΔT

61 cal / 500 g / 1 cal/g °C =ΔT

                             0.12 °C = ΔT

Receptors for hearing are located in the _______.
Inga [223]
Cochlea.

The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.  <span>

These sound waves are then transduced when it reaches the cochlea where hair-like structures interprets the sensory information and is relayed to the brain.</span>
