What is the internal resistance of a 12v battery? 500 ohms What would be the symptoms of a battery with high internal resistance? High resistance, current is restricted, voltage drops on load; battery heats up. Figure 1: Effects of internal battery resistance. A battery with low internal resistance delivers high current on demand. High resistance […]
What is standard fixed point?
What is standard fixed point? Common fixed points: ice point – temperature when pure water ice is in equilibrium with liquid water at standard atmospheric pressure (76mm Hg). steam point – temperature when pure liquid water exists in equilibrium with water vapour at standard atmospheric pressure. Which of the following temperature is the highest? The […]
How long will it take until only 25 percent of the strontium 90 remains?
How long will it take until only 25 percent of the strontium 90 remains? It takes 28.8 years for half of the strontium to decay to 50 grams. This is called one half-life. After 28.8 more years, strontium-90 has decayed to 25 grams. How does half-life work? A medication’s biological half-life refers simply to how […]
Where does the skater have the most kinetic energy?
Where does the skater have the most kinetic energy? AnswerThe skater has the highest amount of kinetic energy when he reaches the lowest point of the track. Potential energy – when he reaches the highest point on the track. What type of energy does the skater have at the 2 m mark? potential energy What […]
What is the movement of energy by waves called?
What is the movement of energy by waves called? In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water […]
What happens when Chlorophyll absorbs light energy?
What happens when Chlorophyll absorbs light energy? what happens when chlorophyll molecule absorbs light: what happens when chlorophyll molecule absorbs light: photosynthesis begins. it becomes excited. This energy passes through other chlorophyll molecules, and into the reaction center of Photosystem II (Electron transport chain). What is the most important function of chlorophyll? Chlorophyll’s job in […]
How much heat does it take to boil water?
How much heat does it take to boil water? The boiling point of water is typically considered to be 100 °C or 212 °F. Pressure and a change in the composition of the liquid may alter the boiling point of the liquid. High elevation cooking generally takes longer since boiling point is a function of […]
What happens at 1.5 degrees warming?
What happens at 1.5 degrees warming? According to the report, with global warming of 1.5 °C there would be increased risks to “health, livelihoods, food security, water supply, human security, and economic growth.” Impact vectors include reduction in crop yields and nutritional quality. What is the cause of climate change Wikipedia? Climate change is caused […]
Is work dependent on angle between force and displacement?
Is work dependent on angle between force and displacement? The acting force on the body : Work is directly proportional to the acting force at constant displacement and constant angle between force and displacement . The displacement of the body : Work is directly proportional to the displacement at constant force and constant angle between […]
Is stored in fossil fuel and released in the form of kinetic energy when burned?
Is stored in fossil fuel and released in the form of kinetic energy when burned? When fossil fuels are burned, chemical energy is released. Does fasting burn muscle? Notably, intermittent fasting is popular among many bodybuilders, who find that it helps maintain muscle alongside a low body fat percentage. SUMMARY There’s no evidence that fasting […]
