accelerating to upat
4.9 on/sh what a ni
in the elerator.
what, will
the
pressure in the elevator​

Answer 1

Answer:

When the elevator is going upwards with acceleration a then net acceleration will be the sum of a and g(acceleration due to gravity).=g+a

∴ Pressure=hρ(g+a)dyne/cm  

2

 

=  

76×13.6×g

76×13.6×(g+a)

​  

cm of Hg.

=1+  

g

a

​  

>1cm of Hg.

final pressure should be more than 76cm of hg
