Physics

is inversely proprotional to its centigrade temperature

is inversely proportional to its absolute temperature

is directly proportional to its centigrade temperature

is directly proportional to its absolute temperature

remains constant also

sound is a longitudinal wave

sound can be reflected and refracted like light

sound travels through a vacuum

sound moves faster in a steel wire than in air

sound can ony be produced by vibrating objects

there is only one lens

the objective lens have a shorter focal length than the eyepiece which is convex

the objective lens has a longer focal length than the eyepiece which is convex

the objective lens has a shorter focal length than the eyepiece which is concave

the objective and the eyepiece are both convex and have the same focal length

recieves from our eye

disperses

absorbs

refracts

reflects

to transmit a given amount of power, the tension in the conducting wire must be high

heat is not lost when current is passed through a conductor

heat is gained when a given power is transmitted

a big transformer is required to transmit power

trasmission of power at low current and high voltage
