BEIJING, Feb. 21 (Xinhua) -- Ever since Chinese President Xi Jinping introduced the term "new productive forces" in September last year, foreign think tanks and media outlets have widely discussed the concept. In a recent high-level meeting, new productive forces were again the focus of discu...
When an electric current is passed through two parallel conductors then due to mutual forces between them, do they move toward each other? If yes, what is the reason behind this? What is electric flux in physics? What causes electric shock - current or voltage? What is electromagnetism and ...
An electric charge, which can be either positive or negative, is a property of matter that causes two objects to attract or repel. If the objects are oppositely charged (positive-negative), they will attract; if they are similarly charged (positive-positive or negative-negative), they will re...
What is electric current? Describe the properties of electric currents. What causes electric shock - current or voltage? Define electric potential. What forces are there in a vacuum? What is the difference between Electro-Motive-Force and Potential-Difference? What is strain energy? What are non-...
"There are many notable signs that China is switching its economy from high-speed growth to high-quality growth, and it is encouraging new quality productive forces to boost and transform into a more innovation-driven, balanced, inclusive, green and open development," Ban Ki-moon, former UN ...
