<h3><u>Answer;</u></h3>

Deflation

<u>Deflation</u> is the process by which wind removes surface materials.

<h3><u>Explanation</u>;</h3>

Erosion refers to a process in which soil, rock, and other surface material are removed from their location and transported to another by natural agents such as water and wind.
<em><u>The main mechanism of wind erosion is deflation. Deflation involves erosion by wind of loose material from flat areas of dry uncemented sediments such as those in deserts, dry lake beds, flood plains etc. The removed particles are then transported to another region where they may form sand dunes on a beach or in a desert.</u></em>

6. A garden hose attached to a nozzle is used to fill a 15-gal bucket. The inner diameter of the hose is 1.5 cm, and it reduces

Vesna [10]

Answer: 1.135 L/s; 1.35 kg/s, 22.57 m/s

Explanation:

Given

Volume of bucket $V=15\ gal\approx 56.78\ L$

time to fill it $t=50\ s$

Volume flow rate

$\dot{V}=\dfrac{56.78}{50}=1.135\ L/s\approx 1.135\times 10^{-3}\ m^3/s$

The inner diameter of the hose $D=1.5\ cm$

diameter of the nozzle exit $d=0.8\ cm$

we can volume flow rate as

$\Rightarrow \dot{V}=Av\quad \quad \text{v=average velocity through nozzle exit}\\\\\Rightarrow 1.135\times 10^{-3}=\frac{\pi }{4}d^2\times v\\\\\Rightarrow 1.135\times 10^{-3}=\frac{\pi }{4}(0.8\times 10^{-2})^2\times v\\\\\Rightarrow v=\dfrac{4\times 1.135\times 10^{-3}}{\pi \times 64\times 10^{-6}}=22.57\ m/s$

Mass flow rate

$\Rightarrow \dot{m}=\rho \times \dot{V}\\\Rightarrow \dot{m}=1\ kg/L\times 1.135\ L/s=1.35\ kg/s$

Hydrogen/hydronium ion concentration

Valentin [98]

Answer:

Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration. So the pH is the -log of the [hydronium ion].

which of the following locations has the largest electric field? A)0.4 cm from a +3.0 uC point charge B)0.2 cm frm a +1.5 uC poi

JulsSmile [24]

<span>Electric field is proportional to q/d^2, where q is the magnitude of the charge and d is the distance. Since all the given units are identical, we can just compare their relative magnitudes without calculating for the exact values.
A) 3/(0.4)^2 = 18.75
B) 1.5/(0.2)^2 = 37.5
C) 6/(0.4)^2 = 37.5
D) 3/(0.2)^2 = 75
Therefore, choice D has the largest electric field of all.
