Answer:
While you may have some incandescent bulbs lying around, once they're gone, they will be gone forever. And you probably won't mourn their inefficiency; since about 90 percent of the energy produced in the bulbs is actually heat instead of light, they are huge energy wasters. While they generally last about 1,500 hours, this is still only a fraction of the lifespan of CFLs. These are lit by an electric current sent through a tube that contains argon and a small amount of mercury gases. These gases generate invisible ultraviolet light, which commingles with a fluorescent coating on the inside of the tube to produce light.

Shadrach Minkins was an African-American fugitive slave from Virginia who escaped in 1850 and reached Boston. He also used the pseudonyms Frederick Wilkins and Frederick Jenkins. He is known for being freed from a courtroom in Boston after being captured by United States marshals under the Fugitive Slave Act of 1850.

Two men were prosecuted in Boston for helping free him, but they were acquitted by the jury.

Answer:
Engel v. Vitale (1962) was a case in which New York State's Board of Regents attempted to force children to pray in public schools. The Supreme Court ruled that this law violated the First Amendment. The ruling affirmed that, in the United States, church and state (religion and government) were separate. If a child attended a public school, he/she should be able to express his/her own religious beliefs in any way he/she sees fit. The case of West Virginia Board of Education v. Barnette (1943) involved forced participation in the Pledge of Allegiance. Two students claimed they could not participate in the pledge based on religious beliefs and sued the state board. Again, the Supreme Court agreed that the students should be allowed to excuse themselves from any ceremonies that offended their religious beliefs.
