Asensor is submerged in a silo to detect any bacterial growth in the stored fluid. the stored fluid has a density of 2.3 grams per cubic centimeters. what is the hydrostatic pressure felt by the sensor at a depth of 30 meters in units ofâ atmospheres

The formula for hydrostatic pressure is:

P = ρgh

where ρ is density = 2.3 g / cm^3, g is gravity = 9.81 m/s^2, h is height of water = 30 m

Therefore,

P = (2.3 g / cm^3 * 1 kg/1000g * (100cm/1m)^3) * 9.81 m/s^2 * 30 m

P = 676,890 Pa  = 6.68 atm

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
