?

I have a class using quartus ii software to type system verilog code to program an FPGA.

I am not very familiar with this program, and have been struggling

I had some code that someone e-mailed me to look over and I saved it to the computer and cannot even figure out how to open the project correctly i can get the code but nothing compiles or is useable. I did open project not file and i believe I opend the highest level in the hierarchy

Also is there sources with helpful videos or tips for learning to use quartus? also system verilog or FPGA

Thanks

What does the code

a += 2

do in a program in C?

Floating point

Run the following computations in single-precision (32-bit) floating-point mode:

1000 + 1

11 / 3

100 - 0.25

100 - 0.3

-100 + 0.3

9000 + 0.0001 - 9005

9000 - 9005 + 0.0001

9000 + 0.01

9000 * 0.01

Answer the following questions in lab2.txt:

Why is there an error in the fourth computation, but not the third? (Hint: how do you encode 0.25 and 0.3 in floating point?)

How does the result of the fifth computation compare to the fourth? Explain. (Hint: look at the hex representations of the results. How does the floating point format handle negative numbers?)

Mathematically, would you expect the same results in computations 6 and 7? Do you observe this result experimentally? Explain. (Hint: try stepping through each computation)

What happens if you try computation 6 in double-precision (64-bit) floating-point mode? Why?

Why is there noticeable error in computation 8, but not 9? (Hint: think of multiplying floating point numbers like multiplying two numbers in scientific notation, how do you do it?)

The root cause of the Ariane 5 rocket failure was isolated to the conversion of a floating point number, which stored the horizontal component of the rocket's velocity, to a 16-bit signed integer. What is the most likely cause of the failure? (Hint: this wasn't some small rounding error, the computed velocity was way off, causing the system to go haywire)

Tip: It might be useful to use the IEEE-754 Floating-point Conversion tool to better understand the representation of floating-point numbers.

We are using bin/bincalc f32 program and running it in the command program. Im not sure how to answer these questions,

Thanks for your help

How much U-235 would be consumed in a fission bomb with a 20 kt explosive yield?

Please explain this to me, Thanks

I have a wireless printer, but up until now I have always just plugged it in to my computer. I loaned my cable to a friend that lost theirs, so I don't have the cable anymore.

I noticed that my printer has wireless setting and I turned the wireless setting on and a blue light started flashing. I then pushed print on my computer but nothing happened. I printed the diagnostic page on the printer and found that it said that the Network name (SSID) was not found. I don't know what this means or how to fix the problem

Any help would be appreciated.

Find the Inverse Laplace Transform

(2s + 16)/(s^3 + 4s + 13)

Work out the convolution t*t^3 using the definition and showing the work (I keep getting it so everything cancels to zero which I don't think is correct)

Thanks

I have to write a paper on the practical applications of differential equations. We are supposed to do 2 examples, and we have to use technology also as part of the assignment.

I was wondering, is there any free online graphing calculators that would let me copy and paste the graph into a microsoft word document?

I want to insert the graph of the equation V(t) = -.2083 e^(-2t) + 5.208 e^(-50t)

Im not sure how to do this and any help is appreciated, thanks!

A real gas is more accurately described using the van der Walls equation: [p + a(n/V)^2](V - nb) = nRT, where a and b are constants. Find an expression, corresponding to the equation, Q = -Win = nRT ln (V1/V2) for an isothermic process, for the work done by a van der Waals gas undergoing an isothermal expansion from V1 to V2.

Can you please explain this to me, Thanks!

Given that a population, P, after t months, can be modeled by the logistic model

dP/dt = .3 P (3.5 - P/40).

P(0) = 30

a) Solve the diff eq

b) Find the population after 2.5 months

c) Find lim P(t) as t -> infinity

A helium balloon occupies 8.0 L at 20 degrees C. and 1.0 atm. The balloon rises to an altitude where air pressure is .65 atm and temp is -10 degrees C. What is the volume when it reaches equilibrium at the new altitude?

Please help me solve this, Thanks!

a car wont crank over when the key is turned. the battery is charged and the open circuit voltage is 12 volts. When a 1 ohm resistor is connected across the battery the terminal voltage drops to 8 volts. The battery manufacturer specifies a 0.1 - 0.25 ohm range for the internal resistance. What is the thevenin equivalent resistance of the battery and is this the reason the car wont start?

please explain how i would solve this problem, Thanks

While camping you boil water to make spaghetti. Your pot contains 2.5 kg of water initially at 10 degrees Celsius. You stoke up the campfire, and as a result the water gains energy at an increasing rate: P = a + bt, where a = 1.1 kW, b = 2.3 W/s, and t is the time in seconds. To the nearest minute, how long will it take to bring the water to a boil.

use the method for homogeneous equations to solve

(xy + y^2) dx - x^2 dy = 0

1) Sketch the solution to the initial value problem and show the solution

dy/dt = 2y - 2yt

y(0) = 3

2) Use a calculator to sketch the direction field and soln curve for dP/dt = sin(t) - Pe^(-t), P(0) = 2

A circuit is composed of a 35.0 ohm resistor and a 0.250 Henry inductor in series, powered by an AC source with frequency of 30.0 Hz. The resulting peak current is 0.100 A.

a) What is the peak voltage of the resistor?

b) What is the peak voltage of the inductor?

c) What is the peak voltage of the power source?

Please explain how to solve this to me, Thanks!!

28. Two mirrors with a 75 degree angle between them. A ray enters the mirror system parallel to the axis. a) How many reflections does it make? b) Through what angle is it turned when it exits the system?

38. A triangular prism with n = 1.52 and alpha = 60 degrees is surrounded by air. A light beam is incident at theta = 37 degrees. Find the angle through which the beam is deflected from the incident after it exits the prism.

34. A parallel plate capacitor has circular plates with radius 50 cm and spacing 1.0 mm. A uniform electric field between the plates is changing at the rate of 1.0 MV/ms. Find the magnetic field between the plates (a) on the symmetry axis, (b) 15 cm from the axis, and (c) 150 cm from the axis.

56. A photon rocket emits a beam of light instead of hot gas. How powerful a beam would be needed for a thrust equal to that of a space shuttle (35 MN)? compare your answer with humanity's total electric power-generating capability, about 1 TW.

60. A cylindrical resistor of length L, radius a, and resistance R carries current I. Calculate the electric and magnetic field at the surface of the resistor, assuming the electric field is uniform over the surface. Calculate the Poynting vector (integral of S*da) over the resistors surface to get the rate of electromagnetic energy flow into the resistor, and show that the result is I^2R. Your result shows that the energy heating the resistor comes from the fields surrounding it. These fields are sustained by the source of electric energy that drives the current.

Please show me how to solve these, Thanks!! I know it is a lot of problems, and I appreciate any help
