Answer:

D. 4x as much

Explanation:

The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.

You can also prove this mathematically. The formula for kinetic energy is

\frac{1}{2}mv^2

The question says: constant mass so we can ignore that for now.

(1/2) * 10^2 is (1/2) * 100 = 50

for the 20m/s ball it would be

(1/2) * 20^2 = 400 * 1/2 = 200

Once again, you see that it is 4x

To simplify the conceptual design, most higher-order relationships are decomposed into appropriate equivalent _____ relationship
LenaWriter [7]

Answer: binary

Explanation:

Conceptual design refers to the early phase of the design process, whereby the outlines of function are articulated. The conceptual design consist of the design of processes, interactions, and strategies. It is the first stage in the database design process.

The output of the conceptual design process describes the main data entities, and constraints of a particular problem domain. To simplify the conceptual design, most higher-order relationships are decomposed into appropriate equivalent binary relationships whenever possible.

Do you think the current system of punishment in the United States works? Why? What would you change?
Simora [160]

Well the fact that jails are overcrowded is one factor that shows it's not working. Some people need help from past traumas, abuse, etc. Not everyone that acts out needs to be incarcerated, they need rehabilitation or counseling. Definitely depends on the crime committed. Therefore substance abuse users would be in rehabilitation. Even Juveniles in detention centers don't benefit from incarceration for certain offenses. There is no rehabilitation in incarceration. There are more criminals in jail and incarceration in my opinion, only for some offenders, is the last option. Now for Sex Offenders, Murderers and Criminals with violent crimes my opinion is completely opposite. Some of those offenders should be dealt with according to their crime. Also, all of the people that have been pardoned and them lessening time for drug traffickers and actual drug dealers (not necessarily users) is just a bad thing to pardon them or let them out because they don't have any violent crimes. Isn't dealing drugs, that are killing people every single day just as bad as a violent crime. In my opinion they can sit and rot for the longevity of their sentence. Some need help and I would fully support that only under some circumstances. Others I would rather not have to live amongst them.
