Question

solve this question so I make brainliest​

Answer 1

Answer:

Here, pitch = 0.5 mm

Least count `= (0.5 mm)/(50) = 0.01mm`

Zero error = `-(50 -45)xx0.01 = - 0.05mm`

Zero correction `= + 0.05 mm`

Thickness of sheet `= 0.5 mm + 25 xx 0.01 mm`

+ `0.05mm

0.80 mm`

please mark my answer as brainliest please

Answer 2

Answer:

Least count : 0.001cm

Actually reading : 0.529cm

Explanation:

Least count =0.001cm

M& R =5mm and 25 divisions

error =−0.004cm

Observed reading =0.5+25×0.001

                            =0.5+0.025

                          =.525cm

Actual reading =.525+0.004

                   =0.529cm
