3.20 × 105 gallons of tar (SG = 1.20) is stored in a 20.0-ft tall storage tank. What is the total mass of the liquid in the tank
lilavasa [31]

Answer:

Mass of the liquid in the tank will be 1.45\times 10^8kg

Step-by-step explanation:

We have given volume of tar V=3.20\times 10^5gallon

1 gallon = 3.785 liter

So 3.20\times 10^5gallon=3.20\times 10^{5}\times 3.785=12.112\times 10^5liter

Specific gravity = 1.2

Density of water =1000kg/m^3

We know that specific gravity =\frac{density\ of\ liquid}{density\ of\ water}

1.2=\frac{density\ of\ liquid}{density\ of\ water}

Density of liquid =1200kg/m^3

So mass of liquid = volume × density

= 12.112\times 10^5\times 1200=1.45\times 10^8kg

So mass of the liquid in the tank will be 1.45\times 10^8kg

PLEASE HELP 30 POINTS Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building mater
jarptica [38.1K]

Logarithmic functions and exponential functions are inverse and opposite of one another

The logarithmic function is y = \log_2(x), and the length at 8 pascals is 3 units

<h3>How to determine the logarithmic function</h3>

The exponential function is given as:

f(x) = 2^x

Express f(x) as y

y = 2^x

Swap the positions of x and y

x = 2^y

Take the logarithm of both sides

\log(x) = \log(2^y)

Apply the rule of logarithm

\log(x) = y\log(2)

Divide both sides by log(2)

y = \frac{\log(x)}{\log(2)}

Apply the change of base rule of logarithm

y = \log_2(x)

When the strength is 8 pascals, we have:

y = \log_2(8)

Express 8 as 2^3

y = \log_2(2^3)

So, we have:

y =3 \log_2(2)

Evaluate log 2 base 2

y =3

Hence, the logarithmic function is y = \log_2(x), and the length at 8 pascals is 3 units
