hey mate ur ans is first
50 = 5*10^1
= (1/2)* 100 = 50
step1:solve first equation then u will get roots name those as a and b
step2: substitute those a and b in the second equation ,then u will get the roots as 9and 1
Assume the length of resistance wire is 5m to make this circle shape. You have to find out how much length is used from point A to B. i.e. the effective resistance.
Hope it helps you.
Do follow me!
Correct Option is :
( a ). 1 and 9Explanation :
Refer the attached picture.
First the no of mats which has to take out is let be x because x is variable and it value can be change.
10 mens or 20 boys made 260 mats in 20 days. So we can take ten mens or twenty boys are equal to each other or we can say that 1 men is equal to 2 boys.
So how many mats will made in by 20 days by 8 mens and 4 boys.
1 mens is equal to 2 boys.
8 mens is equal to 8 × 2 =16 boys.
16 boys + 4 boys = 20 boys.
20 boys can made 260 mats in 20 days.

Hey mateyou can write 5 headlines each from political,economic,sports,
HOPE THIS IS HELPFUL TO YOU..
because point A and B are out of coil .
we know ,point of a and b in air .
so resistance of pin a and b will be equal.
I hopes its helps u.
sorry i am not know i am follow you please check
please mark as brainlist answer
