earnstyle [38]

Answer:

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.

Assuming that 70 percent of the Earth’s surface is covered with water at average depth of 0.95 mi, estimate the mass of the wate
Alla [95]

Answer:

The mass of the water on earth is 5.4537\times10^{20}\ kg

Explanation:

Given that,

Average depth h= 0.95 mi

h=0.95\times1.609

h =1.528\ km

h=1.528\times10^{3}\ m

Radius of earth r= 6.37\times10^{6}\ m

Density = 1000 kg/m³

We need to calculate the area of surface

Using formula of area

A =4\pi r^2

Put the value into the formula

A=4\pi\times(6.37\times10^{6})^2

A=5.099\times10^{14}\ m^2

We need to calculate the volume of earth

V = Area\times height

Put the value into the formula

V=5.099\times10^{14}\times1.528\times10^{3}

V=7.791\times10^{17}\ m^3

Now, 70 % volume of the total volume

V= 7.791\times10^{17}\times\dfrac{70}{100}

V=5.4537\times10^{17}\ m^3

We need to calculate the mass of the water on earth

Using formula of density

\rho = \dfrac{m}{V}

m = \rho\times V

Put the value into the formula

m=1000\times5.4537\times10^{17}

m =5.4537\times10^{20}\ kg

Hence, The mass of the water on earth is 5.4537\times10^{20}\ kg

A solution of baking soda has a pH of 9. Baking soda _______. A. is a base B. is an acid C. is a neutral substance D. could be e
Alex777 [14]
The pH scale goes from 0 to 14. The middle of the scale (7) is neutral. Anything smaller is acidic, and anything larger is basic.

9 is larger than 7, so the solution is basic.

The answer is A.
