Mercury is added to a cylindrical container to a depth d and then the rest of the cylinder is filled with water. If the cylinder
jonny [76]

Answer:

0.10839 m

Explanation:

P_1 = Atmospheric pressure = 1 atm = 101325 Pa

P = Total pressure at bottom of mecury = 1.2 atm

g = Acceleration due to gravity = 9.81 m/s²

h = d = Depth of mercury

\rho_m = Density of mercury = 1.36\times 10^4\ kg/m^3

\rho_w = Density of water = 1000\ kg/m^3

Pressure at the bottom is of the cylinder is given by

P_2=P_1+\rho_wgh\\\Rightarrow P_2=101325+1000\times 9.81(0.7-d)

Pressure at the bottom of mercury is

P=P_2+\rho_mgh\\\Rightarrow 1.2\times 101325=101325+1000\times 9.81(0.7-d)+1.36\times 10^4\times 9.81\times d\\\Rightarrow 1.2\times 101325=123606d+108192\\\Rightarrow d=\dfrac{1.2\times 101325-108192}{123606}\\\Rightarrow d=0.10839\ m

The depth of the mercury is 0.10839 m

Select all that apply. Sound is a ____ wave. longitudinal transverse pressure circular
elena-s [515]
The following apply:
Sound is a LONGITUDINAL wave.
Sound is a PRESSURE wave.
Longitudinal waves are waves in which the displacement of the medium is in the same direction as or opposite direction to the direction of wave propagation. An example of longitudinal wave is sound wave. Sound wave is also considered as a pressure wave as the result of the presence of repeating patterns of high and low pressure regions moving through a medium.

What is the linear speed of a point on the equator, due to the earth's rotation?
kvv77 [185]
The equatorial radius of the earth is
r = 6378 km = 6378 x 10³ m

The earth makes 1 revolution in 24 hours.
The angular velocity is
ω = (2π rad)/(24*3600 s) = 7.2722 x 10⁻⁵ rad/s

The tangential velocity (linear velocity) at a point on the equator is
v = rω
   = (6378 x 10³ m)*(7.2722 x 10⁻⁵ rad/s)
   = 463.8 m/s

Answer: 463.8 m/s
