H2+1/2O2-->H2O
since there are two atoms of hydrogen present in the reactants and in the product you don't need to add any number before H2
we add 1/2 before O2 because only 1 atom is needed for the water molecule
Answer:
It has long been known that static pressure affects middle-ear function and conventional tympanometry uses variations in static pressure for clinical assessment of the middle ear. Middle-ear under-pressures tend to reduce the velocity magnitude more than do middle-ear over pressures.
The effect of middle-ear static pressure on the acoustic response of both structures is similar in that non-zero middle-ear static pressures generally reduce the velocity magnitude of the two membrane components in response to sound stimuli.
This is because direct power has no pulsation (waveform characteristic) that is significant in electromagnetic induction. The gradual increase and decrease of power, at a given frequency, in indirect power is significant in electromagnetic induction. This enables transformers to induce electricity into the secondary coil, from the primary coil, at the core of the transformer.Transformers transform electric power by increasing or decreasing the voltage and current of electricity.
