QUES: (CNN) -- The photographer who took images of former Pakistani Prime Minister Benazir Bhutto moments before her assassination Thursday told CNN he was "surprised" to see her rise through the sunroof of her vehicle to wave to supporters after delivering her speech. Getty Images photographer John Moore captured Benazir Bhutto waving, moments before he heard gunshots. "I ran up, got as close as I got, made a few pictures of her waving to the crowd," Getty Images senior staff photographer John Moore told CNN's online streaming news service, CNN.com Live, in a phone interview Thursday from Islamabad, Pakistan. "And then suddenly, there were a few gunshots that rang out, and she went down, she went down through the sunroof," he said. "And just at that moment I raised my camera up and the blast happened. ... And then, of course, there was chaos." Watch Moore describe Bhutto's final moments " Moore said he was about 20 yards away from Bhutto's vehicle when he took his photographs. Bhutto was rushed to Rawalpindi General Hospital, where she was pronounced dead. Moore said he had been following Bhutto's story since her return to Pakistan in October. He was present October 19 when a terror attack targeting her motorcade in Karachi killed 136 people. In the aftermath of that attack, "The rallies had been very small," because of high security, Moore said. However, the Rawalpindi rally was announced beforehand, he observed. "Whoever planned this attack -- they had time on their hands to plan everything properly, and you saw the results today," he said. Between 5,000 and 8,000 were at the Rawalpindi rally, which was held at a parkground, he said. "We [the news media] all expected it to be filled ... but there were less people there than most of us expected to see," he said. "When I talked with a number of people, they said that people were just afraid to come out, for the simple reason that they all remembered what happened in Karachi." Moore said he himself expected there could be another attack following the Karachi massacre. He said he stayed away from gates at the Rawalpindi parkground, where police were searching people, because he suspected that's where a bomb would go off.

QUES: (CNN) -- Jo-Wilfried Tsonga ended Roger Federer's hopes of winning a record-equaling seventh Wimbledon title on Wednesday as the French 12th seed staged a stunning fightback to reach the semifinals. Federer appeared to be cruising into the last four after winning the first two sets, but Tsonga inflicted the Swiss world No. 3's first defeat from that vantage point in 179 grand slam matches. It was only the third time in the 29-year-old's glittering career that the 16-time grand slam champion had surrendered a two-set lead. Tsonga, ranked 19th in the world, triumphed 3-6 6-7 (3-7) 6-4 6-4 6-4 on Centre Court, serving out to love as he earned a clash with second seed Novak Djokovic. The Serbian, who beat Tsonga in the 2008 Australian Open final, ended the dream run of Australian 18-year-old Bernard Tomic. Tsonga defeated Federer for just the second time in six meetings, their first on grass. "It was amazing. I played unbelievable. It's never easy to come back against Roger. I'm so happy, it's crazy," the 26-year-old told reporters after reaching the semifinals at Wimbledon for the first time. "He's the biggest champion in the sport. He has achieved so much and is the best player in the world. To be two sets down and come back was unbelievable. I served really well. Against Djokovic I will have to come out and do the same again." Federer has now lost in the quarterfinals two years in a row, being beaten by eventual runner-up Tomas Berdych in 2010. "Jo played great. Really from start to finish I don't remember seeing a break point after I broke him in the first game," Federer said.

QUES: Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.
