LETRS Unit 2 Session 1-8 Check For Understanding Answers (VERIFIED, 100% CORRECT) LETRS Unit 2 Session 1 Check For Understanding Answers A student with general phonological awareness can learn to read fluently, even if the student has not yet developed awareness of speech sounds at the phoneme level. False. If a student analyzes the sounds and syllables in a word, it is easier for the student to store the word in semantic memory. True Read the following list of classroom activities....

Magnetic pulse generators are commonly used to send data to the computer about: The speed of the monitored component. Technician A says pulse width modulation (PWM) is measured in a length of time, not a percentage of a cycle. Technician B says that the cooling fan relay is usually controlled by the PCM through PWM. Who is correct? Both A and B When the pressure in the intake manifold increases the fuel pressure regulator on a port fuel injection system: Increases fuel pressure. Tec...

Three reasons for using a vfd - ANS Energy savings Accurate process control Extended equipment life Variable torque loads - ANS Require 1/8 of the power and 1/4 of torque at half speed Constant torque loads - ANS Power is 1/2 if the speed is half Open loop - ANS Vfd runs according to preset values in program Closed loop - ANS Respond to feed back from the system, may be from a plc How do vfds extend equipment life - ANS Reduce elec...

For control purposes, the SCR is a regulated rectifier made from a silicon semiconductor material with a third terminal. Thanks to its high temperature and control capability, Silicon was chosen. In that a 3rd terminal called a gate decides whether the corrective transfer from open circuit, the basic feature of SCR vary from the usual 2-layer semi-circuit diode. b) 1. solid state relay can protect Control circuit From Electro motive Force Emf rather than EMR. 2. Solid state relay is faster th...
