Which evidence supports the inference that Nora is afraid of losing her relationship with her husband? 1) ""no idea what a dangerous condition he was in"" 2) ""how I cam to devise a way out of the difficulty"" 3) ""I had meant to let him in on the secret"" 4) ""It would upset our mutual relations altogether

1. “no idea what a dangerous condition he was in”

Explanation:

This is because, the doctor had already told Nora that the husband's life is in great danger except they moves to the southern part. The husband being an opinionated person would not agreee to such request if they wife tell him the exact truth why they should move.

That is why she had to find a way out by convincing him to move while her husband's diginity still remain intact.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
