Question

calculate rank correlation coefficient from the following data



data in the image below



​

Answer 1

P=VI=I2R

36=I2×9

I=2Amp

I1=156×IT

I2=159×IT

I2I1=(96)

62×9=I2=3Amp

Inet=(2+3)=5

V2Ω=I×R=5×2=10Volt

Answer 2

If the angles of a triangle are in the ratio 2 : 3 : 4, find the angles. - Mathematics

First angle = 180 ° × 2 9 = 40°Second angle = 180 ° × 3 9 = 60°Third angle = 180 ° × 4 9 = 80° ∴ Angles are 40°, 60° and 80°.
