It is a popping resonating sound generated by a lean condition on deceleration. When you suddenly close the throttle, the incoming air is choked off and the closed throttle also causes the bike to return to idle on the very lean idle circuit.
The reactivity series of metals was deduced by performing several experiments in the lab which enabled scientists to arrange metals according to their reactivity with dilute acid, oxygen (air), and water.xides of iron and copper are insoluble. Metals that are less reactive than copper like silver, gold and platinum do not react with oxygen. Note: When aluminum reacts with oxygen, a layer of aluminum oxide adheres and covers the aluminum.
At room temperature, copper has a resistivity of 16.78 nÎ©m. From the above equation, it can be seen that as the thickness and, thus, the cross-sectional area A of the wire increases (for the same length l) the resistance will decrease because of the reciprocal effect upon the value of R as A increases in size.However, this is not the full picture. '..hat is the relationship between wire thickness affecting resistance and 1/r1+1/r2=1/rTotal? i am confused.?
