Question DC Motor is interfaced with Arduino UNO through L293D IC, which is connected on pins 8, 9 and temperature sensor LM35 is connected on pin A4. LCD is connected on pins 2,3,4,5,11, 12. Write a program to: • Rotate the Motor in Clockwise direction, if Temperature in Fahrenheit is more than 100. LCD should display "AIR Fan ON". • If Temperature in Fahrenheit is less than 100 then LCD should display "EXHAUST Fan ON ". Motor should start rotating in anti-clockwise direction. Formula: Temperature in Fahrenheit = ( Input Value from Sensor * 0.48818125)*1.8/32 DO UNO 0 ELE

Given R1=13 kΩ, R2=26 kΩ, R3=39 kΩ, R4=52 kΩ, R5=65 kΩ, V1=250 mV, determine the value of ia. RA RE R + + R 150 mV

11. You are asked to estimate the market value of Ms Mini's house, which has two floors. The first floor is rectangular, 35 feet wide and 45 feet deep. The area of the 335 second floor is about 70% of that of the first floor. The lot size is 45 feet by 100 feet. The lots in the area sell for $6,000 per front foot. The present construction cost for this type and quality of house is $160 per square foot. A personal inspection of the house reveals the following information: (i) The house needs external painting that will cost $2,000. (ii) The house needs minor roof repair that will cost $1,000. (iii) A recent flooding in the basement has caused a damage of $1,500. (iv) A storm door has to be replaced at a cost of $1,300. (v) Fireplace costs $5,000. (vi) Tthe broadloom of the master bedroom has to be replaced at a cost of $1,800. There is no other observable depreciation. Required: What is the value of Ms Mini's house by the Cost Approach?

A 181 ‑turn circular coil of radius 2.03 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 16.5 Ω resistor to create a closed circuit. During a time interval of 0.135 s, the magnetic field strength decreases uniformly from 0.627 T to zero. Find the energy 𝐸 in millijoules that is dissipated in the resistor during this time interval.

The following equations describe the variation of pressure p with veloci 0 p + A og V-2 = X (i) p + B g pv = Y (iii) p + CPV 2 = Z where, A, B, and C are dimensionless constants. X, Y, and Z are values with the same dimensions as pressure, g is the acceleration due to gravity, p is the density of the liquid, and o is the surface tension of the liquid. Which equations are dimensionally homogeneous? 2:33 PM
