Question 9 (b) ,, how do u make a solenoid?
i mean without the iron bar inside but you can draw it
ohkay thanks al0t =]
with the magnets sorry * since they produce a current by changing the magnatic flux
yeah got it, thankew
really helpful
... THANKYOU !!!
using the formula s=ut+1/2at^2
what is u ? and a ?
u--> initial velocity & a--> acceleration
what is intial velocity :S ?u--> initial velocity & a--> acceleration
the starting velocity ,in this question as its not given its zero..
well if it is zero then you did wrong calculation :S you used it as one in your calculation there
you said ^ 2 you did ^3 you said +1 you did *1 ? :S can you type the write equation please
no :S try calculatin ur self by subsitutin the values u'll get it thn..i din take anythin for 'u'
oh nvm i got it just use the area under triangle like a graph 0.5 x 0.6 and 1.2 it will give you the distance which is 0.36
Centripetal force is the force acting towards the center of the circle now to get this force you need to changed direction so friction between tyres and track occurs when the friction is not enough to provde enough force to stay in cirular motion you leave the track
oh sorry i subsituted wrong typin mistake :| oki
