A one-wheeled cart is used to carry 400N load. If the load is at a distance of 30cm from the wheel and the cart is 1.2 m long, what effort should be applied at the handles to lift the load? What are mechanical advantages, velocity ratio and efficiency? Is the efficiency in practice same as calculated one?​

Answers

Answer 1

The load force to effort force ratio is the mechanical advantage. The distance traveled by the effort divided by the load is known as the velocity ratio. Efficiency is a measure of a system's ability to turn input work into productive output work.

Given

Load = 400N

Distance =30cm

Distance = 1.2m

Required to calculate mechanical advantages, velocity ratio, and efficiency

mechanical advantages = Load / Effort

                                        = 400N / Effort

velocity ratio = Distance moved by effort / Distance moved by the load

                      = 1.2m / 0.3m = 4

Critics of the legalization of gay marriage who claimed that it would lead to marriage in general being meaningless were using what type of fallacy in their arguments? a)either/or b)slippery slope c)ad populum d)begging the claim

Answers

The fallacy that critics of the legalization of gay marriage would be used in their argument is the slippery slope fallacy. The correct option is b.

When someone asserts that a specific course of action or event would unavoidably result in a string of unfavorable outcomes without offering sufficient evidence to back up this causal link, they are committing the slippery slope fallacy.

Without demonstrating how this trend will take place, the critics, in this case, assert that allowing gay marriage will result in the meaninglessness of marriage in general. It is significant to emphasize that this misconception ignores the potential for alternate outcomes and oversimplifies the complicated processes involved in societal transformation.

Thus, the ideal selection is option b.

in at least 150 words compare philosophies and constitutionalism

Answers

Philosophies and constitutionalism are distinct concepts, with philosophies encompassing a broad range of ideologies and beliefs, while constitutionalism refers specifically to the principles and practices of governance based on a constitution.

Philosophies and constitutionalism are different in nature and scope. Philosophies encompass a wide range of ideologies and beliefs that shape individuals' views on various aspects of life, including ethics, morality, politics, and the nature of reality. They provide a foundation for individual or collective perspectives on how society should be organized and governed. Philosophies can differ significantly, ranging from liberalism and socialism to conservatism and existentialism.

On the other hand, constitutionalism specifically refers to the principles and practices of governance based on a constitution. Constitutionalism establishes the framework for the exercise of political power, the protection of individual rights, and the distribution of authority within a political system. It places limitations on the power of the government and provides a system of checks and balances. Constitutionalism emphasizes the rule of law, accountability, and the protection of fundamental rights and liberties.

While philosophies provide the broader ideological underpinnings of governance and societal values, constitutionalism translates those principles into concrete legal and institutional frameworks. Constitutionalism ensures that governance adheres to the principles and values espoused by various philosophies, providing a system of rules and structures to guide and regulate political power within a society.

Which valuation technique do you find most useful in your professional field? Why?

Answers

most often, the Discounted Cash Flow (DCF) method is considered the most useful valuation technique in the field of finance and investing. This technique involves estimating the future cash flows of a business or investment and discounting them back to their present value to determine the intrinsic value of the asset. The DCF method takes into account the time value of money and provides a detailed analysis of the potential returns on investment. However, it requires accurate assumptions about future cash flows and discount rates, which can be difficult to predict. Other valuation techniques include comparables analysis and the dividend discount model, which are also widely used and can complement the DCF method.
