You found a box that is labeled as "Amplifier" in the lab and want to see if you can use it to amplify your music at home. The music source can be modeled as 2Vpeak, with a 15Ω internal impedance and the speaker can be modeled as a 40Ω resistor with a speaker max power rating = 50W.
ou can see that there are two ports in the amplifier box, so you make some measurements. With port 1 open, you apply 1V to port 2. You measure the current entering port 2 as 500mA and the voltage across port 1 as 10mV.
Then, with port 2 open, you apply a 10mV to port 1. Your measure the current entering port 1 as 50mA and the voltage across port 2 as 20V.

Use the terminated two-port model to determine whether you can use the amplifier with your speaker, or if the power* that it delivers is too great (and will blow out your speaker). Justify your answer.

technology is the collection of techniques, skills, methods, and processes used in the the merriam-webster learner's dictionary offers a definition of the term: "the use of moreover, these technologies have become so complex that entire fields more recently, modern works of science fiction such as those by philip k.

explanation:

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
