Calculate the radius of a water drop which would just remains suspended in an electric field of 300V/cm and charge with one electron​

Answers

Answer:

electric field (E) = kq/r^2 = 300 V/cm = 30000 v/m

q = ne

no. of electron = 1

q = 1 x (1.6 x 10^-19)

q = 1.6 x 10^-19

E = (9 x 10^9 x 1.6 x 10^-19)/r^2

r^2 = (9 x 16 x 10^-11)/30000

so r = 2.19 x 10^-7 m

What was a challenge that resulted from the Roman Empire’s large size? The empire was lacking in natural resources. It was challenging to trade with other regions. It was difficult to defend all areas from attacks. The empire faced crowding issues due to overpopulation.

Answers

it was difficult to defend all areas from attacks.

The correct option is C.  It was difficult to defend all areas from attacks which was a challenge that resulted from the Roman Empire’s large size.

The Roman Empire was too large to control in a single location, and as a result, tribes attacked, provinces were lost, and no new ones were obtained, which caused the empire to contract.

What challenges did the Roman Empire face?

Surprisingly similar issues plagued the Roman Empire, including violent uprisings, assassinations, overwhelming ambition, civil war, conflicts between the sexes and classes, and debates over the balance between individual freedom and governmental control.

Rome was able to expand its empire in great part by giving many of the people it subdued some kind of citizenship.

History has shown that one of the major causes of the empire's eventual downfall was its enormous size; it had simply become too big to handle and was vulnerable to both internal and external factors. Of course, the Roman Empire was among the biggest of these empires.

training is an indispensable factor to carry on a profession. justify this statement

Answers

Answer:

Better training leads to better processes and Better Work. In today’s ever-changing marketplace, the importance of job training has never been greater. Workforce training is an indispensable way to keep your organization competitive. Employees are human, most will have weaknesses or gaps in their professional skills. Furthermore, most professional people are specialists of one kind or another. Much of what goes on in your organization is likely to fall outside of the training each individual worker already has.

Having a high quality and comprehensive employee training development program enables you to strengthen the skills your workforce does possess as well as to build up knowledge where it is lacking. An employee training development program will bring all of your staff up to a higher standard of competency so that your entire team can share a common set of knowledge and skills. Such a program will repair any weak links that may exist in your organization and cause the workload to be more evenly spread among your workers.

It might be difficult to overstate the importance of ppt in your current training program, and employee development articles in educating your workforce. The importance of training ppt documents stems from their ability to be easily shared, incorporated into larger educational packages, and their tendency to convey critical lessons clearly and succinctly.  But many firms make the mistake of simply mandating that their employees review such-and-such article, or attend so-and-so presentation rather than to incorporate these elements into a comprehensive training program. Unfortunately, organizations that make this mistake likely do not recognize the importance of employee training to an organization.

By providing ongoing workforce training, you will enable one employee to pick up where another left off, keeping them all on the same page without having to provide constant help and supervision. The importance of employee training to an organization should never be underestimated. And, ongoing training can be thought of as the best insurance policy against all sorts of the inevitable changes and the unforeseeable needs that will arise in your organization from time to time.

A)Egyptians did not rely on trade.

B)Egypt's pharaohs controlled economic decisions.

C)Egyptians had no exports.

D)Egyptians did not produce crafts.

Answers

Answer: B) Egypt's pharaohs controlled economic decisions.

Explanation:

The ancient Egyptians had a lot of resources at their disposal but they still traded extensively for goods they were not self sufficient in. The Egyptians and the Mesopotamians were early trade partners whose cultures influenced each other. Egypt primarily exported grain and crafts made with clay from the banks of the Nile.

Egypt's Pharaoh's were very influential with their claim to divinity and so controlled the country in its entirety. They controlled all economic decisions. This was unlike in Mesopotamia where the Kings were influential but trade could be done by individuals.

why do women suffer a double-standard in physical appearance?

Answers

Answer:

The belief that women and men are held to different standards of sexual conduct is pervasive in contemporary American society. According to the sexual double standard, boys and men are rewarded and praised for heterosexual sexual contacts, whereas girls and women are derogated and stigmatized for similar behaviors. Although widely held by the general public, research findings on the sexual double standard remain equivocal, with qualitative studies and early attitudinal surveys generally finding evidence of the double standard and more recent experimental vignette designs often failing to find similar results. In this study, we extend prior research by directly measuring the social status of sexually permissive youth. We use data collected from the National Longitudinal Study of Adolescent Health to relate adolescents’ self-reported numbers of sexual partners to a network measure of peer acceptance. Results suggest that the association between lifetime sexual partnerships and peer status varies significantly by gender, such that greater numbers of sexual partners are positively correlated with boys’ peer acceptance, but negatively correlated with girls’ peer acceptance. Moreover, the relationship between boys’ sexual behaviors and peer acceptance is moderated by socioeconomic origins; sexually permissive boys from disadvantaged backgrounds are predicted to have more friendships than permissive boys from more advantaged backgrounds. Our results thus support the existence of an adolescent sexual double standard and suggest that sexual norms vary by both gender and socioeconomic origins.

I NEED 10 FACTS ABOUT 9/11

Answers

Answer:

[1]   On September 11, 2001, nearly 3,000 people were killed, 400 were police officers and firefighters, in the terrorist attacks at the World Trade Center in NYC, at the Pentagon building in Washington, D.C., and in a plane crash near Shanksville, PA.

[2]   9/11 was not the first terrorist attack on the World Trade Center. A bombing in February of 1993 killed six people.

[3]   On any given workday, up to 50,000 employees worked in the WTC twin towers, and an additional 40,000 passed through the complex.

[4]  After the September 11th attacks on the World Trade Center, the rescue and recovery clean-up of the 1.8 million tons of wreckage from the WTC site took 9 months.

[5]   Passengers aboard United Flight 93, heard about the previous airplane attacks and attempted to retake control of the plane from hijackers. As a result, the hijackers deliberately crashed the plane in a Pennsylvania field instead of at their unknown target.

[6]   While video accounts of the WTC attack aired immediately, no video footage of the Pentagon attack was publicly released until 2006.

[7]   Though both the police and fire departments of New York City had their own emergency response procedures, the two departments did not have a coordinated response plan to a major incident.

[8]   The attack on the World Trade Center on 9/11 resulted in the largest loss of life by a foreign attack on American soil.

[9]  18 people were rescued alive from the rubble of the World Trade Center site.

[10]  Cases of post-traumatic stress are common among 9/11 survivors and rescue workers. Respiratory problems, like asthma and lung inflammation, also developed at abnormal rates for those in and around the World Trade Center during and after the attacks.

Extra Fact:

In 2019, the US Senate passed a bill ensuring that a fund to compensate victims of the September 11th attacks never runs out of money — and that first responders won't have to return to Congress to plead for more funding.
