:) help plz

33--> as simple as that! strain increases means length increases increasing resistance as well.. no need to even think about the cross sectional area..
34--> Sorry I am not sure about this. h4rriet please help! :D
17--> they said 93% is heat while 7% is light... so 93+7=100... answer is simple 7% ((7/100)*100) - I guess, thats how i understood it..

U have to find R first. R=V/I
At point A B and D, ratio of V:I will be higher as V is more than I so ratio will be higher than 1. At C they are almost equal so ratio will almost be 1 so its the smallest value of R

no datas given . how to find r ? > :sneaky:

mcq22...first calculate density =mass/volume, then use density= cuberoot volume to calculate the distance u will get C...
mcq 8...using v1= a*t1
v2 = a*t2
then use 2as= (v2)^2 - (v1)^2
or else use this method , in vertical case lyk this one u need to knw that s= 1/2 at^2 is used...
put values in this eq nd u vl get 2h/(t2^2 - t1^2)
hope u get these...:)

Q .. if ratio of power of x / power of y is 2 ...
what will be the ratio of resistance of x /resistance of y ...
ans is 4 .. but i couldnt get the hint using p=I^2R

A double slit experiment, using light of wavelength 600nm, results in fringes being produced on a ​
screen. The fringe separation is found to be 1.0mm. ​
When the distance between the double slits and the viewing screen is increased by 2.0 m, the ​
fringe separation increases to 3.0mm. ​
What is the separation of the double slits producing the fringes? ​
pls can anyone help?​
