okk..i have attached it...1c...
u have to draw a tangent to the point (where the dent lies)
this way u get the point on the x-axis near 24

24-20 = 4 --> 4/2 = 2

2*12 = 24m!
hope this helped



if u see carefully...the curve touches the x-axis at 25..
but u dont have to take the curve...its the tangent to the curve
therefore the answer lies between    24<= ans <= 28

uh wat r the four equations of motion again :D

s= ut + 0.5a(t^2)
s = (u+v)/2
v = u + at
v^2 = u^2 + 2as

alright let see hopw can i expalin

16.3 (heat from heater +heat from surrounding)  -  2.1(heat from surrounding)  = 14.2 (heat from hetaer)

is tht easier...

wow!...great explanation shogun
tks a lot
u will surely do well in ur physics
best of luck

After all is said and done, more is said than done.

By the time a man realizes that maybe his father was right, he usually has a son who thinks he’s wrong.

u need to knw the value of voltage per square in the CRO when u knw that note down how many squares the crest of the wave goes to n then multiply it with the voltage per square n that gives u the total voltage
