Subsidy
A price support is a type of subsidy. It seems that this is not given in
the choices. However, subsidy is a form of monetary or financial support which
is provided by a local or state sector. It aims to provide economic and social
stability and development. Hence, subsidy encompasses various types of support
funded by either government or non-government offices. It can be given in form
of either direct (money, incentives and etc.) or indirect (insurance,
write-offs and etc.) in procedures.
The pressure of diver = atmospheric pressure + water pressure
atmospheric pressure = 750 mmHg (as given) = 750 / 760 atm = 0.987 atm
Water pressure is
P = hρg
where
h = height of water = 38 ft
1 ft = 0.3048
38 ft = 11.58 m
ρ = density = 1000 Kg / m³
g = gravitational constant = 9.81 m/s2
P = 11.58 X 1000 X 9.81 = 113599.8 Kg / m s^2 Or N /m^2
1 N / m^2 = 1 pa = 9.869 X 10^-6 atm
P = 113599.8 Pa = 1.12 atm
Total pressure = 1.12 + 0.987 atm = 2.107 atm = 2.1 atm (two significant figures)
