A larger vehicle has higher kinetic energy so it needs a longer time to release this energy because it has more so therefore increasing its stopping distance
Answer: Jimmy's Peanut Farm has to decrease its prices by 2.5% in order to achieve a 1% increase in the quantity of peanuts it sells.
Jimmy's Peanut Farm can increase the quantity sold by 1% only when the demand for peanuts increases. Demand for peanuts will increase only when the price of peanuts decrease. The Price Elasticity of Demand measures the responsiveness of demand to a percentage change in price.
The formula for Price Elasticity of Demand (PED) is given by the formula:
We have:
Percentage increase in quantity 1% or 0.01
Price Elasticity of Demand (PED) 0.40
Re-arranging the PED formula above we get,
Substituting the values in the equation above we get,
Answer:
The correct answer is (C) Technological changes have increased the efficiency of oil-fired power plants..
Explanation:
Given that the contribution of fossil fuels constitutes the majority of the current energy mix, and taking into account the growing demand for energy and carbon intensity, we are at a crossroads: designing a new intelligent energy model. The energy challenge we face must have a global response, in which all available, conventional and alternative forms of energy coexist; all those forms of energy that can be produced in a balanced, safe way, with universal accessibility, competitive and respectful with the environment.
Much of what has served us in the past will not work in the future, with the great exception of innovation and technology as they will continue to be the fundamental keys to building a new energy model.
