Answer 1

Having a good working knowledge of English is significant due to its widespread use as a second language, official language in many countries and organizations, influence in international events, and dominance in the digital world.

Having a good working knowledge of English is significant for several reasons:

English is used as a second language by approximately 300 million people worldwide.

More than 60 countries and many international organizations use English as the official or semi-official language, making it essential for communication and collaboration.

The International Olympic Committee conducts meetings only in English, emphasizing its importance in international events and diplomacy.

English is the most widely used language in the world's computers, showcasing its dominance in technology and digital communication.

Having a good command of English allows individuals to effectively communicate and connect with people from different cultures and backgrounds, facilitating business negotiations, enhancing cross-cultural understanding, and enabling participation in global events and opportunities. It also opens up diverse career prospects and fosters a sense of inclusivity in a global society.

Answer 2

In the middle of the roller coaster ride, when it's moving at its fastest, it possesses primarily kinetic energy.

How to explain

At this point, the cart's high speed translates into kinetic energy, which is the energy of motion. As the roller coaster swings to either side (left or right), it gains potential energy.

This occurs because as it ascends the incline, its height increases, converting kinetic energy into potential energy.

This potential energy is due to the cart's position at a higher elevation, resulting in stored energy that can be converted back into kinetic energy when the roller coaster descends.
