Answer:

Explanation:

Bulk modulus (B) =  2.3 x 10⁹ N/m²

B = Δp/ (Δv/v)

Δp = B (Δv/v)

density = mass / volume

d = m/ v

ln d = ln m - ln v

Δd/d = -Δv/v

Δp = B (Δd/d)

Δp = 360 - 1 = 359 atom

= 359 x 10⁵ N/m²

359 x 10⁵ =2.3 x 10⁹ x (Δd/d)

Δd = (359 x 10⁵/ 2.3 x 10⁹) x d

= 156.08 x 10⁻⁴ x 1045

= 16.31 kg/m³

increased density

= 1045 +16.31

= 1061.31 kg/m³

Answer:

The density of seawater at a depth is 1061.3 kg/m³.

Explanation:

Given that,

Pressure = 360 atm

Density at the surface = 1045 kg/m³

Bulk modulus B=2.3\times10^{9}\ N/m

We need to calculate the density of seawater at a depth

Using formula of density

B=\rho_{0}\times\dfrac{\Delta P}{\Delta \rho}

\rho=\rho_{0}\times(1+\dfrac{\Delta P}{B})

Put the value into the formula

\rho=\rho_{0}\times(1+\dfrac{\Delta P}{B})

\rho=1045\times(1+\dfrac{(360-1)\times10^{5}}{2.3\times10^{9}})

\rho=1061.3\ kg/m^3

Hence, The density of seawater at a depth is 1061.3 kg/m³.

Leya [2.2K]

A diverging lens is used to permit clear vision of an object placed at infinity. The focal length of the lens is -100 cm.

<h3>What is focal length?</h3>

The focal length is half of the radius of curvature of the focal lens.

By the lens maker formula,

1/f = 1/v +1/u

where, v is the image distance and u is the object distance.

Give, the object is at infinity and the image must form at 100 cm, the the focal length will be

1/f = 1/ -100 + 1/∞

f = -100 cm

The focal length must be -100 cm for the diverging lens.

Learn more about focal length.

In an economy, the demand for labor is given by the equation W = 15 - (1/200) L and the supply of labor is given by the equation
mr_godi [17]

Answer:

the equilibrium wage rate is 10  and the equilibrium quantity of labor is 1000 workers

Explanation:

The equilibrium wage rate and the equilibrium quantity of labor are found as the point where the equation of demand intercepts the equation of supply, so the equilibrium quantity of labor is:

W_{Demand} = W_{Supply}

15 - (1/200) L = 5 + (1/200) L

15 - 5 =  (1/200) L +  (1/200) L

10 = (2/200) L

(10*200)/2 = L

1000 = L

Then, the equilibrium wage rate is calculated using either the equation of demand for labor or the equation of supply of labor. If we use the equation of demand for labor, we get:

W = 15 - (1/200) L

W = 15 - (1/200) 1000

W = 10

Finally, the equilibrium wage rate is 10 and the equilibrium quantity of labor is 1000 workers
