Which factors determine the amount of electric current in a circuit? switch ammeter voltage resistance
Weegy: Those are your options you listed? User: The power used by an electric tool can be determined by multiplying the _____. resistance times the current current times the voltage resistance times the voltage Weegy: [Power = watts] The power can be determined by multiplying the voltage and the amps. So for example if you have a 500 watt power inverter in your car. You want to know if your drill will be able to run with it plugged in. Figure it out like this. [ The label on the drill has (rated at 9.5 amps). Calculate volts X amps = watts. 110 volts x9.5 amps - - - 1045 watts So the answer would be no the drill would blow the circuit breaker. It may work up to until it started to draw more than 500 watts. In other words if you just pulled the trigger it would probably turn but when you started drilling and put a heavy load on it that when you would exceed the 500 watt limit and blow the fuse. So in this case you have just figured out what size unit you need. In order to run this drill you would need a power inverter larger than 1045 watts. I would say get a 1200 or better still a 1500 watt unit so it wouldn't run at full capacity and overheat. ] User: The rate at which energy is transferred is called _____. power resistance voltage current User: The function of a circuit breaker is to _____. stop a current that is flowing too fast reduce a current that is flowing too fast speed up a current that is flowing too slow stop a current that is flowing too slow Weegy: The function of a circuit breaker is to stop a current that is flowing too fast (More)

If a 0.200-kilogram ball sits on a shelf 2.00 meters from the floor, how much mechanical energy (ME) does it possess? more than 3.92 J exactly 3.92 J less than 3.92 J cannot be determined because kinetic energy cannot be calculated
Weegy: less than 3.92 J User: Gravity is considered what type of force? conservative non-conservative User: When gases, liquids, or solids are in contact with a moving object, the flow of _____ occurs due to frictional forces. heat current electricity radiation Weegy: d User: Thermal energy produced by friction cannot usually be used to do work. True False Weegy: False, Thermal energy can be used to do work User: A generator converts _____ energy into _____ energy. mechanical; chemical mechanical; electrical electrical; mechanical chemical; mechanical User: A 0.200-kilogram ball sits on a shelf 2.00 meters from the floor and then falls to a point 1.00 meter from the floor. Ignoring any affects due to friction, at this position _____. its mechanical energy is 3.92 J its potential energy is 3.92 J its kinetic energy is 3.92 J its potential energy is 1.96 J its kinetic energy is 1.96 J its mechanical energy is 1.96 J Weegy: its potential energy is 0.2*9.8*2 = 3.92 J no work is being done on the object (normal force of shelf up is counteracting force due to gravity down), [ [ so its mechanical energy is zero. the mechanical energy that was required to lift the ball from the floor to the shelf is the same as its present potential energy, or 3.92 J. ] ] User: A geologist studies _____. the earth, rock forms, and strata the origins of words the lives of early communities by examining artifacts the development of language early human culture and development compared to the present day Weegy: the origins of words User: An etymologist studies _____. the earth, rock forms, and strata the origins of words the lives of early communities by examining artifacts the development of language early human culture and development compared to the present day Weegy: the origins of words User: To properly study the human race's past, all five types of historians should be used.

[ ] User: To improve the conclusions from the analyzed data, the historian should include personal bias in his findings. True False User: The two general areas into which the historian divides his material are _____. archaeological remains written records geological reports business records libraries Weegy: *archaeological remains and *written records are the two general areas into which the historian divides his materia User: What two main types of sources does a historian use? bones and pottery maps and secondary primary and secondary Weegy: primary and secondary - - A primary source is a document or physical object which was written or created during the time under study. These sources were present during an experience or time period and offer an inside view of a particular event. [ Some types of primary sources include: ORIGINAL DOCUMENTS (excerpts or translations acceptable): Diaries, speeches, manuscripts, letters, interviews, news film footage, autobiographies, official records CREATIVE WORKS: Poetry, drama, novels, music, art RELICS OR ARTIFACTS: Pottery, furniture, clothing, buildings Examples of primary sources include: Diary of Anne Frank - Experiences of a Jewish family during WWII The Constitution of Canada - Canadian History A journal article reporting NEW research or findings Weavings and pottery - Native American history Plato's Republic - Women in Ancient Greece What is a secondary source?
