Any Type of Doubts in ENg Phy Chem Bio or Math....Ask me here!!!

[Fatima18]

there is one that finds the nth term of a sequence in AP --> l=a+(n-1)d............ l=last term , a=first term, n=number of terms, d=common difference between terms.

there's one more that finds the sum of terms in AP --> 1/2n(2a+(n-1)d) OR 1/2n(a+l)

Im confused..Is it a+ or a- for the first formula?

Thanks for always being a great help.

Can you explain this please? Why is there an opposing emf?

Question 8c.

The induced current i e AC increases when the motor rotates faster.....The motor extracts power from the battery for the motion....the motion causes an induced current which does not flow as the circuit for it is incomplete so it gets wasted......Hope it helped you again

it is a+

 

[Fatima18]

it is a+

Thank u!

A strong beam of α-particles is brought closed to, but not touching, a positively charged metal plate.

Explain why the plate rapidly loses charge (2)

plzz reply asap!!!!

for physics i guess the most imp topics are forces, magnetism, electricity and radioactivity!
which chapta r yuh talkin about??
