The annual number of cigarettes that are sold continues to decline. For the years 2009dash–2018, the equation y equals negative 9.45 x plus 294.3y=−9.45x+294.3 approximates this data. Here, x is the number of years after 2009 and y is the annual number of cigarettes sold in billions. If this trend continues, find the year in which the annual number of cigarettes sold is zero. To do this, let y = 0 and solve for x.

A block which is 4 kg is dropped from a height of 10 meters along an incline where the coefficient of kinetic friction is .40 and the angle of inclination is 50 degrees. Then the block slides along a horizontal surface where the coefficient of kinetic friction is .30 and after 10 meters it attaches onto a spring of spring constant 500 N/m. a) What is the total work done by gravity? By the Normal force? b) What is the work done by friction along the incline? c) What is the work done by friction across the flat surface? d) What is the velocity of the block at the bottom of the incline? e) How much does the block compress the spring? f) What is the initial potential energy stored in gravity and the final PE stored in the spring? g) If the block were to go back after being compressed by the spring, where does it come to a stop? b) What is the work done by this force if F = (y + 3)i – (x – 6)j Newtons? What is the final velocity?

Coursework of Environmental Chemical Engineering 1. Comprehensive case study of air pollution prevention in power plant: a power plant uses a fuel with mass composition of 85% carbon, 1% sulfur, 9% hydrogen, 3% ash, and 2% moisture, the air excess coefficient in the combustion is 1.5, 0.5% nitrogen in air is oxidized to NO. Calculate the gaseous composition of flue gas, explain how these pollutants are formed and their hazards to environment, select technology to reduce the formation of these pollutants during combustion, and design a complete route to purify the flue gas and describe it in details. Not: (1) List necessary reaction equations (2) List necessary equipment (3) Discuss it comprehensively using the course content.

The figure shows an LCR circuit where the input is the voltage $v_i$ and the output is the voltage $v_o$. By consideration of the voltage drops around the circuit: $v_i = L \frac{di}{dt} + Ri + v_o$ (1) Where, $L$ = inductance in the circuit, $R$=resistance in the circuit and $i$ = current around the circuit. $v_o$ is related to the current $i$ by equation (2): $i = C \frac{dv_o}{dt}$ (2) If the parameters are $L$=0.2 H, $R$=1.2 W and $C$=1 F (a) Derive a Transfer Function Model of the System (10 Marks) (b) Determine the locations of the system poles and describe the expected transient response of $v_o$ to a step input to $v_i$ (10 Marks) UPLOAD YOUR SOLUTION AS A SINGLE PDF FILE
