How does wind energy combined with machines cause a sailboat to move? marking as brainliest

Chemistry

Bess [88]3 years ago

Answer:

Wind energy obtained by the machine is converted into kinetic energy as it functions and thus enabling the boat to move.

Together, the forces of drag, from the water, and the pressure from the wind against the sail itself push the craft forward. Angling too sharply into the wind causes the forces on the boat to become unbalanced, and moves the boat sideways in the water.

How many moles are there in 1.2 x 10^2 atoms of sulfur
Mariulka [41]
Avogadro's number tells you that in one mol of element (sulfur) there are 6.022x10^23 atoms...

So,

1 mol : 6.022x10^23 = x mol : 1.2x10^2

x = 1.99 x 10^-22 mol

*Although this should be correct, you might want to check your question again. You probably misinterpret the question... you want 1.2x10^23 !! :) check it.

A 5-gal, cylindrical open container with a bottom area of 120 square inches is filled with glycerin and rests on the floor of an
aleksandrvk [35]

Answer:

a)  68.9 b/ ft²

b)  57.416

Explanation:

Volume of the cylindrical open container V = 5 gal

= (5)(231)

= 11155 in³

different diagrammatic expression has been shown in the attached file below for clear understanding.

Area A = 120 in²

V = hA

    = \frac{1155}{120}

    =  9.625 in

Upward acceleration , a_z= 3ft/s^2

\frac{dp}{dz} = \rho (g + a_z)

dp= -\rho (g + a_z)dz

\int\limits^P}_0 \,dp= -\rho (g + a_z)  \int\limits^0_h \,   dz

P_b = -\rho (g + a_z) h

= (2.4)*(32.2+3) (\frac{9.625}{12})

= 68.9 b/ ft²

b) The flowchart for the resultant force is shown in the  diagram below:

with that:

F_f = P_bA

F_f =\frac{(68.9)(120)}{(144)}

F_f =57.416

Thus,  the resultant force that the container exert on the floor of the elevator during this acceleration = 57.416

How many sodium ions are in the initial 50.00-mL solution of Na2CO3
tresset_1 [31]
From other sources, the given mass of the solute that is being dissolved here is 7.15 g Na2CO3 - 10H2O. We use this amount to convert it to moles of Na2CO3 by converting it to moles using the molar mass then relating the ratio of the unhydrated salt with the number of water molecules. And by the dissociation of the unhydrated salt in the solution, we can calculate the moles of Na+ ions that are present in the solution.

Na2CO3 = 2Na+ + CO3^2-

7.15 g Na2CO3 - 10H2O (1 mol / 402.9319 g) (1 mol Na2CO3 / 1 mol Na2CO3 - 10H2O) ( 1 mol Na2CO3 / 1 mol Na2CO3-10H2O ) ( 2 mol Na+ / 1 mol Na2CO3) = 0.04 mol Na+ ions present
