Hydrogen is compressible fluid

the simplest pressure gauge is the sphygmomanometer

surface tension is the force in the surface acting normally per unit length across any line in the surface of a liquid

according to Archimedes' Principle the buoyant upward force can be greater than the weight of floating body

the inside pressure is less than the outside pressure of a soup bubble

To neglect the energy dissipated in friction

To supply more output energy than it is given as input energy

To exert a large force by application of relatively small one

To convert a rapid movement into a slow one

To transmit force or torque for accomplishes a definite purpose

to measure threshold of hearing

to determine the quality of a sound

to measure heart beat

to detect the movement of the chest of a young fetus

to determine the velocity of blood flow

Defibrillator is the standard items of emergency equipment

An artificial pacemaker can produce repetition rate of 60 to 70 per minute

Electrocautery is performed by a hand piece

ECG is a recording of electrical signals produced by the brain

EEG is most widely used of the bioelectric measurements

lower fundamental frequency

smaller velocity

the same fundamental frequency

greater velocity

higher fundamental frequency

The red and orange focus nearer the lens

The refractive index of the lens is different for the color of light

Various colors in white light do not all focus at the same point

The lens surface is not perfectly smooth

Violet and blue focus farthest away from the lens
