The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If the energy stored by the spring is 12 joules, what is the approximate weight of the spring in pounds?

Answered by answersmine AT 22/10/2019 – 02:34 AM The is the concept of algebra, the weight of the spring can be modeled by the equation;w=0.9sqrt Ewhere;=energy in joules;thus the weight of the spring when the energy is 12 j will be:w=0.9sqrt12w=3.18 g

Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of using this energy to power homes and businesses? Can you think of any consequences to communities or the surrounding environment?

Answer: Yes, Geothermal energy is a renewable source. Explanation: Geothermal energy is a renewable source because its source is generated unlimited amount of heat by the earth core. It is a sustainable energy source. It is also a non-renewable source because it can be re-used multiple times again and again …

How is energy converted in a hydroelectric plant? A) The kinetic energy of water is converted to electrical energy when water flows down the dam's channel and into the transformer. B) The potential energy of water is converted to electrical energy when water flows past a generator. C) The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy. D) The potential energy of water turns the generator's turbines, which results in the production of electrical energy.

Why is water an excellent solvent for most ionic compounds and polar covalent molecules but not for non-polar compounds? A) Water is a polar molecule. B) Water has a charge like an ion. C) Water is a deionizing substance. D) Water molecules have an unusually high kinetic energy in the liquid state.

A)Water is a polar molecule. When talking about solubility, the rule that “like dissolves like” is usually correct. This means that polar substances are soluble in other polar substances. This occurs because the opposite partially charged ends of different polar molecules are attracted to each other. Similarly, the partially charged ends …

How does cellular respiration explain why animals breathe rapidly when they are running? Energy is used up while running, and cellular respiration needs oxygen to produce more energy. Energy is used up while running, and cellular respiration needs carbon dioxide to produce more energy. Glucose is used up while running, and cellular respiration needs oxygen to make glucose. Glucose is used up while running, and cellular respiration needs carbon dioxide to make glucose.

Answer is: Energy is used up while running, and cellular respiration needs oxygen to produce more energy. Cellular respiration creates an energy molecule when glucose is broken down. Balanced chemical reaction for cellular respiration (convert biochemical energy):   C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy, or: glucose + …

What is an example of how you can be proactive about your personal health and wellness? Know your family health history and use reliable resources to research any family illnesses, because this will help you understand risks and available treatments Schedule regular doctor appointments, because getting checked by the doctor ensures that you will not get sick or contract communicable diseases Get extra sleep on days you don’t exercise, because this will help you keep your body composition in a healthy range and avoid changes in weight Use vitamins and performance-enhancing supplements, because they increase energy levels and help build muscles to keep your body physically fit Question 4(Multiple Choice Worth 1 points)

Answered by answersmine AT 22/10/2019 – 04:31 AM Your answer is: Know your family health history and use reliable resources to research any family.illnesses because this will help you understand risks and available treatments.
