AysviL [449]

Answer:

B. The elasticity of demand is -0.126

Explanation:

% Change in Quality demand = -2.65% (negative because of drop)

% Change in price = 21%

Elasticity of demand is given by

\text{Elasticity of demand}=\dfrac{\text{\% Change in Quality demand}}{\text{\% Change in price}}\\\Rightarrow \text{Elasticity of demand}=\dfrac{-2.65}{21}\\\Rightarrow \text{Elasticity of demand}=-0.12619

The Elasticity of demand is -0.12619

How does acceleration due to gravity changes wit depth?
ivann1987 [24]

Decreases

Explanation:

The acceleration due to gravity on a body decreases with depth.

Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.

  • The acceleration due to gravity tend to pull all bodies to the center of the earth.
  • As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
  • But when a body approaches the center of the earth, the acceleration reduces.
  • At depth, the acceleration due to body of a body begins to decrease.
