<span>13.2% First, let's calculate the mass of that 355 ml serving. 1.043 g/ml * 355 ml = 370.265 g Now divide the mass of sugar by the mass of the entire drink. 49 g / 370.265 g = 0.13233765 = 13.233765% So the mass percentage of sugar in that drink is 13.2%</span>

List 10 uses of composite​
REY [17]

Aerospace

Thermoset composites are being specified for wings, fuselages, bulkheads, and other applications in commercial, civilian and military aerospace applications.

Appliance/Business

Thermoset composite are being used in frames, equipment panels, handles and trims in appliances, power tools, business equipment and many other applications.

Thermoset composites for the appliance industry are used in washers, dryers, refrigerators, freezers, ranges, ovens, dishwashers for components that include control panels, handles, knobs, vent trims, side trims, motor housings, kick plates and many others.

Automotive/Transportation/Farm/Construction

Composites are now being used in vehicle and equipment applications, including, panels, frames, interior components and other parts.

Civil Infrastructure

Some composite infrastructure applications include buildings, roads, bridges and pilings.

Construction

Thermoset composites are replacing many traditional materials for home and offices architectural components including fixtures, doors, wall panels, roofing, window frames, moulding, vanity sinks, shower stalls and even swimming pools.

Corrosive Environments

Composites are ideal for applications in corrosive environments, such as chemical processing plants, pulp and paper converting, oil and gas refineries and water treatment facilities.  Common applications include fans, grating, tanks, ducts, hoods, pumps and cabinets.

Electrical

With strong dielectric properties including arc and track resistance, Thermoset components include substation equipment, microwave antennas, standoffs and pole line hardware and printed wiring boards. Applications and components include switchgear,  motor controls,  standoff insulators, control system components,  circuit breakers,  arc chutes, arc shields, terminal blocks,  terminal boards,  metering devices,  bus supports and lighting components.

Marine

With their corrosion resistance and light-weighting attributes, Marine composite applications include boat hulls, bulkheads and other components for military, commercial and recreational boats and ships.

Explain why crushed garlic has more flavor when put in food than a whole clove of garlic.
Zigmanuir [339]

A crushed garlic will have a lot of flavor when placed in food due to the surface area that is in contact with the food. When we have a large piece of garlic, only the external part touches the food and its full capacity is not used. When we reduce the size of the year by crushing the internal parts that were not in contact with the food, now they will be, in addition, liquids are also released due to the pressure exerted on the garlic and these liquids mix more easily with the food and they give it more flavor. For better understanding we can see the following figure:

Simply to understand it, in the figure, there is a clove of whole garlic represented by the rectangle that will have a height of 3 and a width of 1, the units do not matter in this case. The area that is in contact will be equal to 8, but if we divide the garlic into three equal parts, it will have a contact area greater than 12. Therefore, the more we divide the garlic, the more area it will be in contact with the food and will give it more flavor.

Given a solution with a hydroxide ion concentration, oh=3.73×10^-5,what is the ph
Stells [14]

Answer:

  • <em><u>pH </u></em><u>= 9.73</u>

<u></u>

Explanation:

<em>pOH</em> is the negative logarithm of the molar <em>concentration</em> of<em> hydroxide ions </em>and pH is the negative logarithm of the concentration of hydronium ions.

The mathematical expression to determine pOH is:

         pOH=-\log [OH^-]

Where [OH⁻] means the molar concentration of hydroxide ions.

Substituting:

        pOH=-\log {(3.73\times 10^{-5})

       pOH=4.43

<em>pH </em>and <em>pOH</em> are related by the equation:

           pH+pOH=14

From which:

           pH=14-pOH\\\\pH=14 - 4.43\\\\pH=9.57\leftarrow answer
