Yes, away goals count double in the European Cup. This means that if a team scores more away goals than their opponent over the course of two legs, those goals will carry more weight in determining the winner. This rule is used as a tiebreaker when the aggregate score is level after both legs of the tie. **

Jean-Jacques Rousseau is often criticized for his double standard in his views on gender roles. While he advocated for equality and freedom in his political philosophy, he held traditional and sexist views on the roles of men and women in society. He believed that women should be submissive to men and should focus on domestic duties, which contradicts his ideas of equality and freedom. This double standard has been a point of contention among scholars and critics of Rousseau's work. **

It is a matter of debate whether the German government is playing a double game in climate protection policy. On one hand, Germany has been a leader in promoting renewable energy and setting ambitious climate targets. However, critics argue that the government has not done enough to phase out coal and reduce emissions from sectors like transportation. Some believe that Germany's continued reliance on coal and slow progress in reducing emissions could be seen as contradictory to its climate goals. **

Doubling the height of an object or structure means increasing its vertical measurement by a factor of two. This would result in the object or structure being twice as tall as it was before. For example, if a building is 50 feet tall and its height is doubled, it would then be 100 feet tall. This type of change can have significant impacts on the appearance, functionality, and stability of the object or structure. **

Doubling the radius of a circle means increasing the distance from the center of the circle to any point on its circumference by a factor of 2. This also means that the diameter of the circle will be doubled, as the diameter is equal to twice the radius. As a result, the area of the circle will be quadrupled, and the circumference will be doubled. **

Double-glazed windows have an advantage over double windows because they are specifically designed to provide better insulation and energy efficiency. The two panes of glass in double-glazed windows are separated by a layer of air or gas, which helps to reduce heat transfer and minimize the loss of indoor heat during the winter and the entry of outdoor heat during the summer. This results in lower energy bills and a more comfortable indoor environment. Additionally, double-glazed windows also provide better sound insulation compared to double windows, reducing outside noise and creating a quieter living space. **

To calculate a double sum, you simply add up all the terms in the sum. For example, if you have a double sum of aij, where i ranges from 1 to m and j ranges from 1 to n, you would calculate it by adding up all the terms aij for each combination of i and j. To calculate a double product, you multiply all the terms in the product. For example, if you have a double product of aij, where i ranges from 1 to m and j ranges from 1 to n, you would calculate it by multiplying all the terms aij for each combination of i and j. **
