Question

who will answer first and correct I will mark him/her brainliest​

Answer 1

Answer:

asI is directly proportional to N

so I1/I2=N1/N2-equation1

I1=350,N1=4

Case1

I2=?,N2=9

put value of this in equation1

350/I2=4/9

4I2=350×9

I2=787.5

case2

I1=350,N1=4

I2=525,N2=?

350/525=4/N2

350N2=4×525

N2=6
