b. Write 2 – 3 sentences explaining redshift and what it led scientists to conclude about the universe.

c. Scientists have proposed three models of the universe that describe three different futures for the universe. Write 2 – 3 sentences comparing the future of the universe according to the closed and open models.

Despite the movement control order MCO (lockdown) in place, many Malaysians continued with their favorite past time - eating and hanging out at food courts and restaurants on the first day. Many even took public parks to exercise despite those having been closed for two weeks as part of a move curb the infection of Covid-19. How can you influence these people to take this MCO (lockdown) seriously?

In the midst of COVID-19, it is reported that over 195 million people will lose their jobs and many small businesses have already closed around the world as a result. Central Banks across the world have been advised to institute policies to help stabilize their economies. Discuss whether central banks should implement expansionary or contractionary monetary policies to achieve stabilization. Discuss arguments for and against each policy direction. Discuss tools that can be used.

Often, branches or divisions are allocated a share of corporate-office costs. If a branch or division is closed then:

Can you give me any information and equations/pictures you can for:

1.Op amp bandwidth limitations/ gain bandwidth product

2.negative feedback

3.closed loop gain

4.input bias current

I have a test tomorrow and those are the four things I forgot all about so please explain them and any information I may need on those topics.

Thank you

The shape of a limacon can be defined parametrically as

                                   r = r0 + cos θ,

                                   x = r cos θ,

                                   y = r sin θ.

When r0 = 1, this curve is called a cardioid. Use this definition to plot the shape of a limacon for r0 = 0.8, r0 = 1.0, and r0 = 1.2. Be sure to use enough points that the curve is closed and appears smooth (except for the cusp in the cardioid). Use a legend to identify which curve is which. This is python programming

Calculate the relative (sub-space) topology with respect to the usual (metric) topology in R (the set of real numbers), for the following sub-sets of R:

X = Z, where Z represents the set of integers

Y = {0} U {1 / n | n is an integer such that n> 0}

Calculate (establish who are) the closed (relative) sets for the X and Y sub-spaces defined above.

Is {0} open relative to X?

Is {0} open relative to Y?

Prove the following Closure Properties with respect to Context Free Languages.

1. Show that Context Free Languages are Closed under union(∪), concatenation(·), kleene star(*).

(Hint: If L1 and L2 are Context Free languages then write Context Free grammar equivalent to L1 ∪ L2, L1 · L2, L∗ 1 )

2. Show that if L1 and L2 are Context Free Languages, then L1 ∩ L2 is not necessarily Context Free.

(Hint: Use Proof by Counter Example)
