Learn MoreThe maximum amount of charge you can store on the sphere is what we mean by its capacitance. The voltage (V), charge (Q), and capacitance are related by a very simple equation: C = Q/V. So the …
Learn MoreThe process. During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Learn MoreStorage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C. Hydrogen can also be stored on the surfaces of solids (by adsorption) or within ...

Learn MoreSevere stress can limit sperm production. Take steps to relax and reduce stress, if possible. Since it takes around 2.5 months for new sperm to be produced, it''ll take some time for lifestyle changes to have an effect on the health of the sperm in your semen, so don''t expect your sperm health to improve overnight. FAQs about the sperm lifecycle
