3. Now use the brown knob at the opening of the hose to adjust the angle at which water comes out. When water comes out at an an
Alenkasestr [34]

Answer:

Due to brown knob which controls its angle.

Explanation:

When water comes out at an angle instead of going straight up, water does not shoot as high as before because its speed is controlled by the brown knob in order to throw water in another angle. If we adjust the brown knob present at the opening of hose pipe in a straight angle the water shoot very high because water moves with high pressure and no barrier is present between its way.

lozanna [386]

Answer:

The answer is below

Explanation:

Charlee's law states that the volume of a gas is directly proportion to the temperature of the gas at constant pressure. That is:

V = kT, where V = volume and T = temperature, k = constant. Therefore:

V / T = k

\frac{V_1}{T_1}=\frac{V_2}{T_2}

Given that: V_1=3\ m^3, T_1=20^oC=(20 + 273)K=293\ k,T_2=60^oC=(60 + 273)K=333\ k.\\\\\frac{V_1}{T_1}=\frac{V_2}{T_2}\\\\\frac{3}{293}=\frac{V_2}{333}    \\\\V_2=\frac{3}{293}*333\\\\V_2=3.41\ m^3\\

The new volume is 3.41 m³. That is it expands by 0.41 m³

What’s the first step you would take to build a voltaic cell?
TiliK225 [7]

Answer:

In a voltaic cell, current is produced by connecting an oxidation reaction half cell to a reduction reaction half cell in an electrolyte solution. Oxidation and reduction reactions (redox reactions) are chemical reactions involving a transfer of electrons from one atom in the reaction to another. When two different oxidation or reduction reactions are connected electrically by connecting the cathode to the anode, a current is formed. The direction depends on the type of reaction taking place at the terminal.

The first step would be to determine metals to be used as the cathode and the anode.
