For projectile motion on level ground assuming negligible air resistance (the initial angle being neither 0o nor 90o): is the acceleration ever zero?
Answers
No, For projectile motion on level ground assuming negligible air resistance the acceleration can never be zero because of gravity.
What is projectile motion?When an item or particle (a projectile) is launched toward the surface of the Earth and moves along a curved route only under the influence of gravity, this is referred to as projectile motion (in particular, the effects of air resistance are passive and assumed to be negligible). Galileo demonstrated that this curving path was a parabola, however it can also be a straight line in the unique situation where it is hurled straight up. Ballistics is the study of such motions, and this trajectory is a ballistic trajectory. Gravity, which works downward and gives the item a downward acceleration toward the Earth's center of mass, is the sole force of mathematical significance that is actively acting on it. The object's inertia means that no outside force is required to keep the horizontal velocity component of the object's motion in motion. Additional study is necessary to take other forces into accounts, such as internal propulsion (as in a rocket) or aerodynamic drag. A ballistic missile is a missile that is only guided for the brief time it is powered up, and the rest of the time it follows the rules of classical physics.

Answers
In the 1973 case of Gagnon v. Scarpelli, the Supreme Court held that a probationer is constitutionally entitled to counsel in a revocation-of-probation proceeding if the imposition of imprisonment is a possible outcome.
This decision aimed to protect the rights of individuals on probation and ensure a fair process in determining whether probation should be revoked.
The Court emphasized that probationers have a legitimate interest in maintaining their conditional freedom, and the possible loss of liberty due to revocation proceedings warrants the need for legal representation. However, the right to counsel is not absolute; it depends on the specific circumstances of the case. Factors such as the complexity of the case, the probationer's ability to present their case effectively, and the potential consequences of revocation may influence the decision to provide counsel.
Gagnon v. Scarpelli clarified that due process must be observed during revocation proceedings, and legal representation is a crucial aspect of ensuring fairness. This ruling ultimately supports the idea that the Constitution's guarantees extend beyond the initial criminal trial to other stages of the criminal justice process, including probation revocation. By safeguarding probationers' rights, the Court recognized the importance of maintaining a fair and balanced justice system.

Answer:
Actually, President Trump does not have the power to reopen the economy, and that’s a good thing. The men who wrote the Constitution understood the danger of giving too much power to any one person.
There are good arguments on both sides as to when and how fast to reopen the economy. In my view, the answer will vary state by state and industry by industry. There’s also an enormous amount of uncertainty as to exactly how to determine the optimal policy. In that environment, there’s a great advantage to having these decisions be made at as local a level as possible. Thus, while I suspect that Sweden’s current policy is not optimal, that Nordic country is doing a great service to Europe by providing evidence on the consequences of an alternative policy path.
Giving too much power to any one person is dangerous, especially when that person might be influenced by political considerations that go beyond the best interest of the country as a whole:
In phone calls with outside advisers, Trump has even floated trying to reopen much of the country before the end of this month, when the current federal recommendations to avoid social gatherings and work from home expire, the people said. Trump regularly looks at unemployment and stock market numbers, complaining that they are hurting his presidency and reelection prospects, the people said.
That’s not to say Trump’s views are necessary wrong; rather that the procedure he uses to reach decisions is not reliable. Thus I’d still favor local control even if in one particular case you could convince me that the views of the person who happened to be president at the time were superior to the views of the average mayor or governor. In the long run, competition between states will produce better governance than central planning.

Answers
When thinking about American freedoms or liberties, modern legislators, courts, and scholars must weigh the benefits between Freedom and Security.
As the world becomes more complex and diverse, there is an increasing demand for security measures to prevent potential threats to national security.
However, these measures often come at the expense of individual freedoms and civil liberties. Therefore, it is crucial to strike a balance between protecting the nation and preserving the rights and freedoms of citizens.The tension between freedom and security is not a new concept, but it has become more pronounced in recent years. With the rise of terrorism and cyber threats, many are pushing for more surveillance, stricter immigration laws, and other measures that they believe will increase national security. However, critics argue that these measures may infringe on individual rights and freedoms, including privacy, freedom of speech, and due process.To find a balance between freedom and security, legislators, courts, and scholars must consider various factors. These include the severity of the threat, the effectiveness of the proposed security measures, and the potential impact on civil liberties. Ultimately, the goal should be to create policies that enhance security without compromising fundamental freedoms. Achieving this balance will require ongoing discussion, debate, and compromise, and will likely remain a challenge for years to come.Know more about the civil liberties.

the only presidential election in which the gallup poll erred badly was
Answers
The only presidential election in which the Gallup poll erred badly was the 1948 election, primarily due to sampling issues, non-response bias, late campaign developments, and methodological limitations.
How did the Gallup poll err in the 1948 presidential election?The Gallup poll, known for its long-standing history of accurately predicting election outcomes, experienced a significant error in the 1948 presidential election. The error was primarily attributed to the challenges faced by the poll in accurately capturing the voter sentiment and preferences during that election cycle.
During the 1948 election, the incumbent President Harry S. Truman, a Democrat, faced challenges from Republican candidate Thomas E. Dewey and the third-party candidate Strom Thurmond of the States' Rights Democratic Party (also known as the Dixiecrats). Public opinion and media coverage during the campaign period seemed to favor Dewey, leading many pollsters, including Gallup, to predict his victory.
However, on election day, the results turned out to be quite different from what the polls had projected. Harry Truman secured a surprise victory, defeating Thomas Dewey and Strom Thurmond. This unexpected outcome shocked the public and the polling community, as it showed a significant discrepancy between the poll predictions and the actual election results.
There were several reasons behind Gallup's error in the 1948 election:
1. Sampling issues: The Gallup poll had difficulties accurately representing the diverse electorate due to limitations in sampling techniques and coverage. The sample used may not have been fully representative of the population, leading to skewed results.
2. Non-response bias: The response rate to the Gallup poll might have been lower among certain demographic groups, leading to a biased sample. Those who chose not to respond might have held different political opinions than those who did, resulting in an inaccurate representation of the electorate.
3. Late campaign developments: The 1948 election saw significant campaign developments and events, including Truman's vigorous campaigning and his "whistle-stop" train tour. These late developments may have influenced voters' preferences in ways that were not adequately captured by the polling conducted earlier in the election cycle.
4. Methodological limitations: The polling methods and techniques used by Gallup at the time might have been less sophisticated compared to modern polling methodologies. The reliance on telephone surveys and limited data collection techniques could have contributed to the inaccurate predictions.
The error in the 1948 presidential election highlighted the challenges faced by pollsters in capturing and predicting voter sentiment accurately. It also served as a turning point for the polling industry, prompting improvements in sampling techniques, data collection methods, and statistical modeling to enhance the accuracy of future election predictions.

During the #FeesMustFall campaign in South Africa, which aimed to address issues of university tuition fees, there were instances where students' human rights were violated.
Some examples include:
1. Excessive Use of Force: Security forces, including the police, were involved in clashes with protesting students. There were reports of excessive use of force, including the use of rubber bullets, tear gas, and physical violence, leading to injuries and violations of students' right to freedom from cruel, inhumane, or degrading treatment.
2. Arbitrary Arrests and Detentions: Students participating in peaceful protests were sometimes arbitrarily arrested and detained by authorities without proper legal justification. These actions violated their rights to freedom of expression, assembly, and due process.
3. Restriction of Freedom of Expression: There were instances where university administrations imposed restrictions on the freedom of expression of students involved in the protests. This included disciplinary actions, threats of expulsion, or restrictions on public gatherings and demonstrations, undermining their right to freely express their views and engage in peaceful protest.
4. Suppression of Academic Freedom: Some students and academics faced disciplinary actions or intimidation for expressing dissenting views or participating in the protests. This infringed upon their rights to academic freedom, which includes the freedom to teach, research, and engage in open and critical discourse.
5. Lack of Access to Education: The overarching issue that sparked the #FeesMustFall campaign was the limited access to affordable higher education. High tuition fees and financial barriers prevented many students, particularly those from marginalized backgrounds, from accessing quality education, thus violating their right to education.
