A car slows down from a velocity of 25 m/s to 5. 0 m/s in 8. 0 seconds. What is the acceleration of the car?

the volumes of two similar solids are 210 m3 and 1,680 m3. the surface area of the larger solid is 856 m2. what is the surface a

kolezko [41]

The surface area of the smaller solid is found to be 214 square meters.

<h3>What is Surface area?</h3>

The surface area is given as the sum of the area of all the faces of a three-dimensional object.

The same shape has equivalent ratio of the surface area to volume. It is given as:

$\rm \dfrac{\sqrt{area_1}}{\sqrt{area_2}}=\dfrac{\sqrt[3]{Volume_1} }{\sqrt[3]{Volume_2} }$

On considering the power of 6 at both the sides of the equation:

$\rm \dfrac{area_1^2}{area_2^2}=\dfrac{volume_1}{volume_2}$

Considering area 1 and volume 1 for the larger solid, and area 2 and volume 2 for the smaller solid, substituting the values give:

$\rm\dfrac{(856\;m^2)^3}{(area_^2)^3}=\dfrac{(1680\;m^3)^2}{(210\;m^3)^2}$

By solving the above equation, the area of the smaller solid is found as 214 square meters. Thus, option B is correct.

ladessa [460]

The matching of the demand as relatively elastic or relatively inelastic can be done as;

Klaus' demand for orange juice (Relatively elastic)

Amanda's annual demand for coffee(Relatively elastic)

Jackson's demand for mystery novels(Relatively inelastic)

Hermy's demand for Minute Maid orange juice(Relatively inelastic)

Olivia's daily demand for Starbucks latte(Relatively inelastic)

Stephen spends a very little part of his income on soda(Relatively elastic)

Xavier's demand for his economics textbook(Relatively inelastic)

<h3>What is Elasticity of demand?</h3>

Elasticity of demand can be regarded as the variation on the concept of demand.

It should be noted that elastic demand involves change in quantity demanded as a result of change in price.
