WILLL GIVE BRAINLIST. For this assignment you'll be making another circuit diagram that is a little more complex and will require a little problem solving. Here is the senario:
The circuit must first turn on a light, then be able to turn on and off a motor with another switch. There must
also be an LED indicator light that turns on when the motor is also on. (remember that an LED is a light but it's
a light emmiting diode, so it is not the same symbol as a typical light)
Must include:
• 2 switches
light
• LED
motor

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
