Answer:
222.5 Gpa
Explanation:
From definition of engineering stress, 
where F is applied force and A is original area
Also, engineering strain, 
where l is original area and 
is elongation
We also know that Hooke's law states that 
Since A=20 mm* 20 mm= 0.02 m*0.02 m
F= 89000 N
l= 100 mm= 0.1 m
By substitution we obtain
Answer:
hi-he = 0
pi-pe = positive
ui-ue = negative
ti-te = negative
Explanation:
we know that fir the sub cool liquid water is
dQ = Tds = du + pdv ............1
and Tds = dh - v dP .............2
so now for process of throhling is irreversible when v is constant
then heat transfer is = 0 in irreversible process
so ds > 0
so here by equation 1 we can say
ds > 0
dv = 0 as v is constant
so that Tds = du .................3
and du > 0
ue - ui > 0
and
now by the equation 2 throttling process
here enthalpy is constant
so dh = 0
and Tds = -vdP
so ds > 0
so that -vdP > 0
as here v is constant
so -dP =P1- P2
so P1-P2 > 0
so pressure is decrease here
Answer:
I know it is C)Virtual reality
Explanation:
Look at the clues
story about putting on a headset ( virtual reality head set!)
seeing a digital world (A virtual reality world)
they could walk around in (Fake walking you are basically jogging in place)
explore in order to see what ancient Benin looked like (Looking at a real place only digitally)
as if they were really there ( they think they are actually there)
The only reason I know all of this is because I have done virtual reality multiple times and I LOVED it SUPER fun ( I was doing archery) :) Hope this helps!
