2.Sound waves with frequencies beyond 20,000 Hz are called?

3.Pots have wooden handles to minimize heat transfer by?


Put an explanation(optional) (Science about Light, Heat and Electricity)

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

this means that the temperature of both substances will be equal

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
