QUES: Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

QUES: The Domestic Violence Legal Assistance Program fills the gap of legal resources for domestic violence survivors who can't afford an attorney. Domestic violence survivors in Jackson, Vicksburg, Hattiesburg, Oxford and Pascagoula can all get help. Julia Crockett, deputy director of Central Southwest Mississippi Legal Services Corp., said the program expects to help nearly 1,000 domestic violence victims. Crockett said legal help gives domestic abuse survivors a way to rebuild their lives. "They have been made to feel by the abuser that no one is going to help them do anything, so when they come to us they are desperate," she said. "Those who need legal help and don't get it feel totally lost. Because then they feel like they are forced to stay in that situation." Crockett said the program, funded by a $300,000 grant from the U.S. Justice Department, has no economic restrictions on who can get help. Legal services typically helps the poor. Gladys Bunzy, who said she was in an abusive relationship with a boyfriend for eight years, said such a program is long overdue and could be a lifeline for those escaping violent relationships. "When I finally made up my mind to leave, I had a restraining order put against him and that was $50 but that was $50 well spent to me," said Bunzy, 40. "For people who can't afford it, this will be a godsend ... If a woman knows she is going to get some help that will be a burden off her mind, if the law will help her keep that person away from her." Gwen Bouie-Haynes, project director of the Domestic Violence Services Center for Catholic Charities Inc., said often domestic violence survivors do not have the money to seek legal representation. "Legal assistance is a major issue for women fleeing a domestic violence situation," she said. "Often times women are in need of immediate legal assistance services for the protection of the mother and the child. To get a protective order you need to be represented by an attorney." Crockett said the pilot program was launched in 1998 at the Haven House Family Shelter Inc., a domestic violence shelter for women and children in Vicksburg. The program has helped victims in 90 court cases, and 150 legal counseling sessions have been held there.

QUES: (CNN) -- Cuba will pardon more than 2,900 prisoners, the government said Friday, though U.S. subcontractor Alan Gross is not among those who will be freed. The decision to release the prisoners follows "numerous requests" from their family members and religious institutions, and is a humanitarian gesture, said Cuban President Raul Castro. Among those who might be freed are prisoners over the age of 60, along with those who are sick, female or young with no previous criminal record. With some exceptions, prisoners convicted of spying, terrorism, murder and drug trafficking will not be released. Those who will be freed have already served a "important" part of their sentences and exhibited good behavior, according to an official statement published on the state-run website Cubadebate. The jailed American, Gross, will not be among those pardoned, the Cuban Interests Section in Washington said. Gross was jailed in December 2009, when he was working as a subcontractor on a U.S. Agency for International Development project aimed at spreading democracy. Castro has accused him of importing satellite equipment to connect dissidents to the Internet, and this year Cuba's highest court upheld the 15-year sentence imposed on Gross for committing crimes against the security of the state. He has maintained his innocence and said he was trying to help connect the Jewish community to the Internet. Castro, speaking to the National Assembly, said that 86 prisoners from 25 countries would be among those released in coming days. He cited the upcoming visit of Pope Benedict XVI as one of the motivations behind the move, which he said showed the "generosity and strength of the revolution." The pope has said he plans to visit Mexico and Cuba before Easter.

QUES: Johnnie had a set of small volumes of English verse, extensively annotated by his own hand, which Stoddard had brought to her early in their acquaintance, leaving it with her more as a gift than as a loan. She kept these little books after all the others had gone back. She had read and reread them--cullings from Chaucer, from Spenser, from the Elizabethan lyrists, the border balladry, fierce, tender, oh, so human--till she knew pages of them by heart, and their vocabulary influenced her own, their imagery tinged all her leisure thoughts. It seemed to her, whenever she debated returning them, that she could not bear it. She would get them out and sit with one of them open in her hands, not reading, but staring at the pages with unseeing eyes, passing her fingers over it, as one strokes a beloved hand, or turning through each book only to find the pencilled words in the margins. She would be giving up part of herself when she took these back. Yet it had to be done, and one miserable morning she made them all into a neat package, intending to carry them to the mill and place them on Stoddard's desk thus early, when nobody would be in the office. Then the children came in; Deanie was half sick; and in the distress of getting the ailing child comfortably into her own bed, Johnnie forgot the books. Taking them in at noon, she met Stoddard himself.
