Question

PLZZ fast...I have testttt​

Answer 1

Answer:

Explanation:

By this , we mean that to balance the atmospheric pressure at that certain place , 76 cm of Hg ( mercury ) is needed .

•• The SI unit of pressure is Pa .

1 Pa = 100000 dyne .

It means atmospheric pressure at that place is equal to pressure exerted by base of tube filled with 76 cm of mercury column.

Answer 2

conversion factor used:  1cm Hg=1330 Pa

since the question is asking to convert to SI unit, SI unit of pressure is Pascal(Pa)

so using conversion factor,76 cm Hg=76*1330 Pa

= 1.0108 * 10⁵
