Answer:

Explanation:

Equation of photosynthesis:

6CO2(g) + 6H2O(l) --> C6H12O6(s) + 6O2(g)

From the above equation, on the RHS, The oxygen during photosynthesis comes from split water molecules. During photosynthesis, the plant absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled or broken down to extract electrons and protons in the presence of ultraviolet light and converted into simple sugar and oxygen.

Equation of the water breakdown:

2H2O --> O2 + 4H+

Answer:

End product of photosynthesis.

Explanation:

Photosynthesis is a process that plants undergo in the manufacture of their food. This is done in the presence of sunlight which is trapped by their coloring pigment called chlorophyll and reactants such as Carbon dioxide and Water.

6CO2+6H2O= C6H12O6+ 6O2

The oxygen gas which is a waste product of photosynthesis is released into the atmosphere and used by animals in respiration.

A 200-mm lever and a 240-mm-diameter pulley are welded to the axle BE that is supported by bearings at C and D. A 860-N vertical

Pachacha [2.7K]

Answer:

A 200mm lever and a 240 mm diameter pulley are welded to the axle BE that is supported by bearings at C and D. If a 860N vertical load is applied at A when the lever is horizontal, determine (a)the tension in the cord, (b)the reactions at C and D. assume that the bearing at D does not exert axial thrust.

see explanation

Explanation:

Part a

The tension in the cord

$\sum M = 0$

860(200) - T(120) = 0

T(120) = 172000

T =1433.33N

The tension in the cord (T) = 1433.33N

Part b

Apply the moment law of equilibrium at point D about y-axis.

$\sum M_D_y = 0$

$C_x = (120)-T(40)= 0$

sustitute 1433.33N for T

$C_x (120)-(1433.33)(40)\\\\C_x (120)=57333.2\\\\C_x=477.78N$

The reaction at C along x-axis 477.78N

Apply the moment law of equilibrium at point D about x-axis

$\sum M_D_z = 0$

$-C_y (120)+860(80+120)=0\\\\-C_y(120)=-17200\\\\y=1433.33N$

The reaction at C along y-axis is 143.33N

Apply the force law of equilibrium along z direction.

$\sum F_z=0$

$C_z=0$

The reaction at C along z-axis is 0N

Apply the force law of equilibrium along x direction.

$\sum F_x=0$

$C_x+D_x+T=0$

substitute 477.78N for $C_x$ and 143.33N for $D_x$

$477.78N+D_x+1433.33N=0\\\\D_x=-1911.11N$

The reaction at D along x-axis is -1911.11 N

Apply the force law of equilibrium along y direction.

$\sum F_y=0$

$C_y+D_y-860=0$

substitute 1433.33 for $C_y$

$1433.33+D_y-860=0\\\\D_y=573.33$

A cruise ship is moving at constant speed through the water. The vacationers on the ship are eager to arrive at their next desti

MArishka [77]

Answer: 1. higher than it was before they started running

Explanation: As the vacationers run towards the back(stern) of the ship the exerting more pressure against the pressure exerted by the wave supporting the moving ship,the pressure exerted on the moving ship will be increased, leading to a slight increase in the speed of the ship compared to the speed before they started running towards the back(stern) of the ship.

Fill in the blanks about Newton’s First Law of Motion:

Afina-wow [57]

Objects want to continue doing what they’re doing because they are “lazy.” This is called law of inertia.

Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that state unless it is being acted upon by an external force. This law is also called the law of inertia because it depends on mass.

From the given question, we can fill gaps as follows;

Objects want to continue doing what they’re doing because they are “lazy.” This is called law of inertia.
