What is Elasticity? (best answer will get marked brainliest)

Firdavs [7]

Answer:

In economics, elasticity is the measurement of the percentage change of one economic variable in response to a change in another.

An elastic variable (with an absolute elasticity value greater than 1) is one which responds more than proportionally to changes in other variables. In contrast, an inelastic variable (with an absolute elasticity value less than 1) is one which changes less than proportionally in response to changes in other variables. A variable can have different values of its elasticity at different starting points: for example, the quantity of a good supplied by producers might be elastic at low prices but inelastic at higher prices, so that a rise from an initially low price might bring on a more-than-proportionate increase in quantity supplied while a rise from an initially high price might bring on a less-than-proportionate rise in quantity supplied.

Elasticity can be quantified as the ratio of the percentage change in one variable to the percentage change in another variable, when the latter variable has a causal influence on the former. A more precise definition is given in terms of differential calculus. It is a tool for measuring the responsiveness of one variable to changes in another, causative variable. Elasticity has the advantage of being a unitless ratio, independent of the type of quantities being varied. Frequently used elasticities include price elasticity of demand, price elasticity of supply, income elasticity of demand, elasticity of substitution between factors of production and elasticity of intertemporal substitution.

Elasticity is one of the most important concepts in neoclassical economic theory. It is useful in understanding the incidence of indirect taxation, marginal concepts as they relate to the theory of the firm, and distribution of wealth and different types of goods as they relate to the theory of consumer choice. Elasticity is also crucially important in any discussion of welfare distribution, in particular consumer surplus, producer surplus, or government surplus.

In empirical work an elasticity is the estimated coefficient in a linear regression equation where both the dependent variable and the independent variable are in natural logs. Elasticity is a popular tool among empiricists because it is independent of units and thus simplifies data analysis.

A major study of the price elasticity of supply and the price elasticity of demand for US products was undertaken by Joshua Levy and Trevor Pollock in the late 1960s..

Which pair of chromosomes is the s3x chromosomes? Why?

d1i1m1o1n [39]

Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The chromosomes of the 23rd pair are called allosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males.

What type of heat transfer is used to fry an egg in a pan and how can you tell?

Deffense [45]

Answer: Option (B) is the correct answer.

Explanation:

A process in which transfer of heat occurring when one object touches another object is known as conduction.

For example, when a pan is heated and then an egg is placed over the pan. Then there will be transfer of heat from pan towards the egg.

As a result, the egg gets cooked because the egg was touching the pan.

Hence, we can conclude that it is conduction because the egg is touching the pan.

The charge of most alkaline earth metals.

frutty [35]

Answer:

2+ charge

Explanation: The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have higher ionization energies. In most cases, the alkaline earth metals are ionized to form a 2+ charge

Hope this helps, have a great day :)

Block A of mass M is at rest and attached to the top of a spring. The block compresses the spring a distance d from its uncompre

Anni [7]

Answer:

a) k = Mg / d , b) v = √2gh , c) v_{f} = $\frac{2}{3} \ \sqrt{2gh}$ , d) x² + 6d x - $\frac{8}{3}$ dh = 0

e)the spring must compress a greater distance.

Explanation:

a) when the block of mass M is placed on the spring, we have an equilibrium condition,

∑ F = 0

$F_{e}$ - W = 0

k d = Mg

k = Mg / d

b) let's use the concepts of energy to find the velocity of the block just before the collision

starting point. Position when released

Em₀ = U = m g h

lowest point. Right at the point of shock

$Em_{f}$ = K = ½ m v²2

as there is no friction, energy is conserved

Em₀ = Em_{f}

mg h = ½ m v²

v = √2gh

c) The velocity of the two blocks after the collision, we define a system formed by the two blocks, in such a way that the forces during the collision are internal and the moment is conserved

initial instant. Just before the crash

p₀ = 2M v + M 0

final instant. Just after the shock, before the spring compression begins

p_{f} = (2M + M) v_{f}

the moment is preserved

p₀ = p_{f}

2M v = 3M v_{f}

v_{f} = ⅔ v

v_{f} = $\frac{2}{3} \ \sqrt{2gh}$

d) now we work with the joined system after the collision, let's use the concepts of energy

starting point. After shock, before beginning spring compression

Em₀ = K = ½ (3M) $v_{f}^2$

Em₀ = 3/2 M (\frac{2}{3} \ \sqrt{2gh})²

Em₀ = 4/3 M gh

final point. With the spring fully compressed

Em_f = K_e + U = ½ k x² + (3M) g x

in this case we have taken the zero of gravitational potential energy at the point where the blocks collide, as there is no friction, the energy is conserved

Em₀ = Em_f

4/3 M g h = ½ k x² + 3M g x

½ k x² + 3Mg x - 4/3 Mgh = 0

we substitute the expression for k

$\frac{1}{2}$ ( $\frac{Mg}{d}$ ) x² + 3Mg x - $\frac{4}{3}$ Mgh = 0

$\frac{x^{2} }{2d}$ + 3 x - $\frac{4}{3}$ h = 0

to find the value of the spring compression, the second degree equation must be solved

x² + 6d x - $\frac{8}{3}$ dh = 0

x = [-6d ± $\sqrt{(36 d^{2} - 4 \frac{8}{3} dh) }$ ] / 2

x = [-6d ± 6d $\sqrt{ 1 - \frac{32}{3 \ 36} \ \frac{h}{d} }$ ]/2

x = 3d ( -1± $\sqrt{ 1 - 0.296 \frac{h}{d} }$ )

e) If the collision elastic force would not lose any part of the kinetic energy during the collision, therefore the speed of the block of mass M would be much higher and therefore the spring must compress a greater distance.
