A battery stores ___ energy. A. electrical B. chemical C. thermal 相关知识点: 试题来源: 解析 B。解析:电池储存的是化学能,电池通过化学反应来提供电能。选项A电能是电池释放出来的能量,不是储存的能量,选项C热能不是电池储存的能量形式,所以答案是B。反馈...
learn more what is a battery? a battery is a device that stores electrical energy in chemical form and converts it into electricity. it essentially consists of one or more electrochemical cells that generate an electric current when a chemical reaction occurs. can i recharge all types of ...

The battery provides a potential difference of 96 V. After switch S is closed, how much charge in coulombs A charged particle q=-8.0 mC is released from rest at point A. At point B the kinetic energy of the particle is equal to 4.8 J. What is the electr...
complicated, but this could have been worded better. if it were my show, here's what i would say about batteries. there are two main things to consider with your battery choice. can it produce enough current to drive your motor and does it have enough stored energy to last you enough ...
While there has been real progress in the e-plane industry, the technical challenges that remain are keeping everyone’s feet firmly on the ground. A battery, even a lithium one, only provides 250 watt-hours per kilogram; compare this to liquid fuel, which has a specific energy of 11, 89...
Like most electric cars, the Stella Terra stores energy in a battery(电池).Thanks to its powerful solar panels and its battery, when it’s sunny, the car can run for 710kilometers a day. Stella Terra has a top speed of 145 kph. The car weighs just 1,200kilograms. That’s about two...
Over time, the energy stored in the battery is gradually turned into light (and heat) in the lamp. This is why the battery runs flat.Picture: A battery like this stores electrical potential energy in a chemical form. When the battery is flat, it means you've used up all the stored ...

Why is the chemical energy in a battery a form of potential energy rather than kinetic energy?What Is Energy:Energy is the ability to do work. Energy comes in different forms and can be converted between them, but due to the law of conservation of energy, en...
