Answer:

The distance between the tank and the upstairs tap is lesser than the distance between the tank and the downstairs tap so water comes out with more force in the downstairs tap than from the upstairs one.

The pressure exerted by water. As the depth of water increases, the pressure also increases.The distance between the tank and the upstairs tap is lesser than the distance between the tank and the downstairs tap so water comes out with more force in the downstairs tap than from the upstairs one.

Suppose a 10.0 mL sample of an unknown

mote1985 [20]

The concentration of HCl is equal to 2.54mol/L.

<h3>Mole calculation</h3>

To solve this question, one must use the molarity calculation, which corresponds to the following expression:

$M = \frac{mol}{v}$

Thus, to find the molarity of the sample, the following calculations must be performed:

$V_f = 10ml + 625ml = > 635ml$

$\frac{0.004mol}{xmol} =\frac{1000ml}{635ml}$

$x = 0.00254 mol$

So, 0.00254 moles were added per 10ml, so we can do:

$\frac{0.00254mol}{xmol}= \frac{10ml}{1000ml} \\x = 2.54mol/L$

So, the concentration of HCl is equal to 2.54mol/L.

What do we need to learn about inclined planes

Troyanec [42]

Answer: Inclined plane, simple machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the incline is less than the weight being raised, discounting friction. The steeper the slope, or incline, the more nearly the required force approaches the actual weight.
