What is no work force? The force exerted by the person is an upward force equal to the weight of the box, and that force is perpendicular to the motion. If there is no motion in the direction of the force, then no work is done by that force. What is no work force give […]
Why do I feel sick during a storm?
Why do I feel sick during a storm? Approaching storms lower the air pressure. When atmospheric pressure decreases body tissues swell slightly. This can put increased pressure on joints and sinuses. Low temperatures also causes blood viscosity, or thickness. Does thunder affect mood? Thunderstorms are dramatic events, so it’s not surprising that they often bring […]
Can a bad fuel pump cause vapor lock?
Can a bad fuel pump cause vapor lock? Still, a modern fuel-injected system can suffer from vapor lock, not only if pressure in the fuel line drops (faulty fuel pressure regulator or fuel pump, for example) and the fuel line is subjected to high temperatures, but also modern engines that may reach between 248 and […]
What is the most important force driving erosion?
What is the most important force driving erosion? Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. What is the biggest driver for soil […]
What is the major source of energy for the body?
What is the major source of energy for the body? Carbohydrates are the body’s main source of energy. The fruit, vegetables, dairy, and grain food groups all contain carbohydrates. What are the 3 most important vitamins? 10 Essential Vitamins Your Body Needs – Comvita Magnesium – This mineral plays an important role in muscle contractions. […]
What do the four elements symbolize?
What do the four elements symbolize? Ultimately what you manifest in the physical world can be attributed to a characteristic of earth, air, fire and water. Symbolically the four elements represent patterns of energy that transform life and by understanding their influences can be used as a tool for self-development. Whats is my soul? Your […]
What happens when you reverse the current in a coil?
What happens when you reverse the current in a coil? When a coil drains a charged capacitor, the flow of charge in the coil does not stop, and the coil will “charge up” the capacitor again, but with reversed voltage. The voltage across the capacitor reverses, and the energy flow reverses, yet the direction of […]
Why does binding energy decrease?
Why does binding energy decrease? The above figure illustrates that as the atomic mass number increases, the binding energy per nucleon decreases for A > 60. As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus. In other words, the BE/A has decreased. What […]
What are insulators short answer?
What are insulators short answer? Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good insulators. What are the uses of insulators? A thermos is an insulator used to keep liquids warm. Insulators work as protectors. They may protect heat, […]
Why is shale gas bad?
Why is shale gas bad? But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas. This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well. Is shale gas a renewable resource? Shale gas is non-renewable, and also polluting but […]
