Discussion: Patents & Copyrights

Article 8 of the US Consitution empowers Congress, in part, "To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries."

Some economists consider that patents & copyrights (what is called "intellectual property" or "intangible property") in their current form contribute to stifling innovation and to the unequal distribution of income by taking advantage of monopoly profits. Here is a short discussion of the benefits and costs of patents & copyrights. And here is a discussion of the effects of monopolies on income & wealth (Links to an external site.).

In several paragraphs, discuss whether in your view the patent & copyright system in the United States is perfect as it is, or if it should be modified, and in what way. Please justify your response with evidence from an academic-level outside source.

A force of 95N is needed to push a 11kg object up a 37degree incline at a constant velocity. the block is then pushed down the incline and released. calculate the magnitude and direction of acceleration of the block after the release as it slides down the incline

Why these four options' premiums are higher than others and why some are equal. (European put, American put, European put is a down-and-out barrier option and American put is a down-and-out barrier option. )

How much of the third mortgage payment will go to pay down the principle?

Home Price: $339,000 USD

15% down payment of selling price

25 year term loan with a 3% annual interest rate

1. What is an enzyme?

2. How does an enzyme work? how does an enzyme, such as amylase, break down polysaccharides?

3. how does this compare to your mechanism by which saccharides break down in the stomach? Explain.

4. Do all sugars produce glucose when they break down?

5. Why is mother's milk lactose instead of maltose? What might be the difference between the two?

-A typed answer would be best, if not, please neat handwriting, thanks! :)

Carlos and Shannon are sledding down a snow-covered slope that is angled at 12.0° below the horizontal. When sliding on snow, Carlos’s sled has a coefficient of friction μ_k = 0.100; Shannon has a “supersled” with μ_k = 0.0100. Carlos takes off down the slope starting from rest. When Carlos is 2.60 m from the starting point, Shannon starts down the slope from rest.

How far have they traveled when Shannon catches up to Carlos?

The only way to pay down the national debt is to have a budget surplus. The only way to have a budget surplus is to increase tax revenues (increase taxes), cut government spending, or both. When is the best time to increase taxes and cut spending? So, when is the best time to start paying down the national debt?

What do you think will happen if we try paying down the national debt during a recessionary gap (when we should be running a budget deficit)?

A 4.50 kg solid cylinder with radius 10.0 cm is allowed to roll down a uniform slope that has been inclined at 22°. The cylinder is stationary at the top and the length of the incline is 5.50 meters.

1. What percentage of the total KE is rotational KE at the bottom of the ramp?

2. What is the angular acceleration of the cylinder as it rolls down the ramp?

3. Find the velocity of the cylinder at the bottom of the ramp.

4. What is the net torque applied to the rolling cylinder during its motion down the ramp?

You go out to the barn and start up the egg collecting machine. Eggs slide down a 30 degree ramp with a coefficient of kinetic friction of 0.2. What is the acceleration of the egg as it moves down the ramp?

If the ramp is two meters long, how fast are the eggs moving when they hit the bottom?

If we assume that the eggs are spherical with a radius of 3 cm, mass 200 grams and roll down the ramp instead of sliding, now recalculate how fast they are moving when they reach the bottom.
