This means that water will not labour at hundred ?C , but at a lower temperature , devising your water not as het up as on sea-level , making cooking meter longer5-What are the varying factors that affect the pitch (frequency ) of a vibrating draw ? How are these factors coverled in a twineed musical instrument such as a violinThe speed and wavelength of the waves formed by striking an object .

A musician controls the frequency through the string s tension and density , by pr essing some of the strings6-If you destiny ! to see yourself full in a plane mull over , the mirror inescapably to be only half your height .

This is because the light received by the eye traveled in a straight imbibe as if it came from tramp the mirror . The mirror is also laterally inverted , means the figure s right will bet as the mirror image s leftReferencesLeigh , J .R (1988 . Temperature measurement and control .
