Can hydrogen be used as cooking fuel? In addition to these applications, hydrogen can also be used as a cooking fuel. In many developing economies, a high percentage of domestic energy demand is related to cooking, which primarily relies on fossil and biomass fuels. What are the advantages and disadvantages of hydrogen? Hydrogen Fuel Cell […]
How the nervous system works with the circulatory system?
How the nervous system works with the circulatory system? The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate […]
How is energy converted in a hydraulic plant?
How is energy converted in a hydraulic plant? Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. What is the proper sequence of energy changes that occur in […]
Which type of cell would bacteria be?
Which type of cell would bacteria be? prokaryotic cells Is bacteria considered a cell? Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA. Why […]
What happens when chlorine gas is treated with cold and dilute caustic soda?
What happens when chlorine gas is treated with cold and dilute caustic soda? Solution. When chlorine is passed through cold and dilute caustic soda solution, a mixture of sodium hypochlorite and sodium chloride is formed. How does sodium react with water? When sodium is added to water, the sodium melts to form a ball that […]
What is a plants main source of energy?
What is a plants main source of energy? 3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy […]
Why is B used for Y-intercept?
What are the two categories of self-concept?
What are the two categories of self-concept? The self-categorization theory developed by John Turner states that the self-concept consists of at least two “levels”: a personal identity and a social one. In other words, one’s self-evaluation relies on self-perceptions and how others perceive them. What are the three parts of self-concept? Self-concept is an individual’s […]
How are charges for ions written?
How are charges for ions written? The charge numbers for ions (and also subatomic particles) are written in superscript, e.g. Na+ is a sodium ion with charge number positive one (an electric charge of one elementary charge). Which type of charges are present in ions give one example? A positively charged ion is known as […]
Can change in potential energy be negative?
Can change in potential energy be negative? potential energy is scalar quantity and a change in scalar can be either positive or negative but force is a vector and the negative rate of change of potential provides you force -its magnitude as well as its direction. gravitational potential energy is taken to be zero at […]
