Answer:
A or B you choose
Explanation:
This is called current electricity or an electric current. A lightning bolt is one example of an electric current, although it does not last very long. Electric currents are also involved in powering all the electrical appliances that you use, from washing machines to flashlights and from telephones to MP3 players.
what is an electrical current, amp, ampere Current is the flow of electrons. When a circuit is closed then a current of electrons can flow and when a circuit is open then no current can flow. We can measure the flow of electrons just like you can measure the flow of water through a pipe.
The amount or cost that the user of the energy-efficient bulb save during 100h of use will be $0.319.
<h3>How to calculate the cost?</h3>
For the 11.0W bulb, it should be noted that the value will be:
= 11.0 × 100 × (1/1000) × 0.110
= $0.121
The 40W bulb will be:
= 40 × 100 × (1/1000) × 0.110
= $0.44
Therefore, the amount that will be saved will be:
= $0.44 - $0.121
= $0.319

Answer:
Faya vei Abhikesh brass hahahahahaha
Explanation:
The correct answer should be kinetic molecular velocity. Which is a
complex term for the speed of molecules. The faster the molecules move
the more liquid the chemical will be, with the fastest being gaseous
molecules. The slowest ones are things that are solid. This is easily
observed on water that is slowest when ice and fastest when water vapor.
Answer:
The specific heat of liquid water is about 4184 J/kg at 20 °C.
So, <u>Correct choice</u> - [C] 4186 J / kg ° C
