What is the best type of energy storage? Lithium-ion batteries What are the main methods of energy storage? Energy can be stored in a variety of ways, including: Pumped hydroelectric. Electricity is used to pump water up to a reservoir. Compressed air. Electricity is used to compress air at up to 1,000 pounds per square […]
What is the direction of average velocity?
What is the direction of average velocity? Average velocity is the ratio of total displacement to total time. Its direction is the same as the direction of the moving object. Even if the object is slowing down, and the magnitude of the velocity is decreasing, its direction would be still the same as the direction […]
What is a good U value for insulation?
What is a good U value for insulation? The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k. What is the most energy efficient […]
What does a changing magnetic field causes?
What is the main reason for acid mine drainage?
What is the main reason for acid mine drainage? Acid mine drainage (AMD) is the runoff produced when water comes in contact with exposed rocks containing sulfur-bearing minerals that react with water and air to form sulfuric acid and dissolved iron. This acidic run-off dissolves heavy metals including copper, lead, and mercury which pollute ground […]
What animals eat seagrasses?
What animals eat seagrasses? Expand/Collapse What animals eat seagrasses? Sea turtles, manatees, parrotfish, surgeonfish, sea urchins and pinfish feed on Florida seagrasses. Many other smaller animals feed on the epiphytes and invertebrates that live on and among seagrass blades. How do seagrasses get their energy? Seagrasses have roots, veins, and leaves. Seagrasses, like other plants, […]
What is effective overburden pressure?
What is effective overburden pressure? When the soil is subjected to some load, it transfers the load to water in the pores and soil grains. This is defined as effective overburden pressure and otherwise will be called as inter-granular stress or effective stress. It increases with increasing depth of soil. What is Geostatic pressure? 1. […]
What can be separated into several elements?
What can be separated into several elements? Compounds Can two elements form more than one compound? Law of multiple proportions, statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small […]
What do frogs do to protect themselves?
What do frogs do to protect themselves? The frog has enemies that will eat them. The skin will secret and cover the body with the poison and this will deter the enemy from eating them. Some use colors to protect themselves. Some will be very brightly colored body (especially red and yellow) to warn enemies […]
What is voltage in a series circuit?
What is voltage in a series circuit? Voltage. In a series circuit, the voltage is the sum of the voltage drops of the individual components (resistance units). Is voltage the same in series capacitors? When capacitors are connected in series and a voltage is applied across this connection, the voltages across each capacitor are generally […]
