Where do we use chemical energy? Chemical batteries: Store chemical energy to be changed into electricity. Biomass: Combustion reaction converts chemical energy into light and heat. Natural gas: Combustion reaction converts chemical energy into light and heat. Food: Digested to convert chemical energy into other forms of energy used by cells. How does the body […]
What is the energy change in storage battery while charging?
What is the energy change in storage battery while charging? By charging a battery, we convert electrical energy into chemical energy. A battery, on the contrary, in use, converts chemical energy into electrical energy. When an electric cell is completely changed we get? In electric cell, chemicals that is electrolyte gets divided into ions and […]
How can charging current be reduced?
How can charging current be reduced? As the battery voltage nears fully charged, current will decrease. If you adjust potentiometer R2 so that the output voltage is 13.6v-13.7v at room temp (25°C/77°F), you can leave the charger on the battery indefinitely. Is 3.1 amp a fast charger? A USB device generally uses very little amps […]
Why Japan is so rich?
Why Japan is so rich? Why is Japan so rich ?? Japan has close economic ties with the United States, European Union, Latin America, Australia, China and many others. The country has developed one of the world’s most powerful economies based entirely on imported raw materials. Who is richest country in world? For example, Iceland […]
What energy transformation happens when a hybrid car slows to a stop?
What energy transformation happens when a hybrid car slows to a stop? Hybrid car includes Regenerative braking technology that cause wheel to slow down and converts mechanical energy produced to electrical energy and stored it back into the battery. How do Hybrid cars use less energy? “Regenerative braking” is another fuel-saving feature. Conventional cars rely […]
Do I live near a nuclear power plant?
Do I live near a nuclear power plant? Quick: where’s the nearest nuclear power plant? Currently, if a radiological emergency occurs, the Nuclear Regulatory Commission recommends that anyone living within 10 miles of a plant to tune in to their local radio or television Emergency Alert System and heed the instructions from state or local […]
Que es el Movimiento rectilineo uniformemente variado ejemplos?
¿Qué es el Movimiento rectilineo uniformemente variado ejemplos? Por ejemplo, si dejas caer una moneda al suelo (caida libre), esta realizará un movimiento rectilíneo uniformemente acelerado (m.r.u.a.) o movimiento rectilíneo uniformemente variado (m.r.u.v.). En este apartado vamos a estudiar las ecuaciones y las gráficas que definen a este movimiento. ¿Cuáles son los tipos de movimiento […]
What is the maritime effect?
What is the maritime effect? The effect of an ocean’s airflow on the climate of the surrounding areas, also known as the maritime effect, is generally milder temperatures and a decreased variation in temperatures. Precipitation is more common in areas with a maritime climate, as moisture levels are higher near the ocean. What are the […]
What is the purpose of units?
What is the purpose of units? For most quantities a unit is necessary to communicate values of that physical quantity. For example, conveying to someone a particular length without using some sort of unit is impossible, because a length cannot be described without a reference used to make sense of the value given. What are […]
What is the center of an atom is called?
What is the center of an atom is called? The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles. […]
