Can light be converted to energy? Solar panels use a curious bit of science called the photovoltaic effect to convert one form of energy into another. Here’s how solar panels harvest light, converting it into electricity. They can do this because of something called the photovoltaic effect, which converts solar energy into electrical energy. Does […]

How do you know if a compound is solid? If the melting and boiling points are both below room temp, you have a solid. If they’re both above room temp, the compound is a gas. If the boiling point is above room temp and the melting point is below, the compound is a liquid. Is […]

What is the dimensionally wrong equation? The dimensionally wrong equations cannot be correct physically because the number of physical quantities themselves willnot be matched regardless of numerical value. 2. A physical quantity has both magnitude and direction. Which formula is dimensionally correct? Pressure = Momentum per unit volume per unit time. Is there an 8th […]

What must you operate the exhaust blower? You must operate the exhaust blower before starting a boats inboard gasoline engine to remove fuel vapors. So you must look for the engine, fuel etc. these are all the precautionary steps for our safety. How long should a ventilation blower be operated after fueling? four minutes What […]

What is KCL formula? According to Kirchoff’s Current Law (KCL), the sum of all currents entering a node equals to the sum of all currents leaving it. The current IR1 in this simulation divides into two – IR2 and IR3 – and is, thus, equal to their sum: IR1 – IR2 – IR3 = 0. […]

Can all physical changes be reversed? Physical changes can further be classified as reversible or irreversible. Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas),freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change. What are 3 physical […]

Is carbon used in batteries? The type of carbon plays a major role in improving the performance of electrodes used in batteries and fuel cells. Clearly, carbon is an important material for batteries and fuel cells. Which battery is better lithium or alkaline? Lithium, an exceptionally light metal, gives lithium batteries the highest energy density […]

Is nerve damage in the ear permanent? Sensorineural hearing loss is permanent. No surgery can repair damage to the sensory hair cells themselves, but there is a surgery that can bypass the damaged cells. How do you treat hearing loss in one ear? How is hearing loss in one ear treated? surgery to repair the […]
