Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower.

This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69. (See Frequencies of notes.) Distance in this space corresponds to musical intervals as understood by musicians. An equal-tempered semitone is subdivided into 100 cents. The system is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C (61) can be labeled 60.5.

Norfolk () is a county in East Anglia in England. It borders Lincolnshire to the west and north-west, Cambridgeshire to the west and southwest, and Suffolk to the south. Its northern and eastern boundaries are the North Sea and, to the north-west, The Wash. The county town is Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000).

The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is not a National Park although it is marketed as such. It has similar status to a national park, and is protected by the Broads Authority.

Norfolk was settled in pre-Roman times, with camps along the higher land in the west, where flints could be quarried. A Brythonic tribe, the Iceni, inhabited the county from the 1st century BC to the end of the 1st century AD. The Iceni revolted against the Roman invasion in AD 47, and again in 60 led by Boudica. The crushing of the second rebellion opened the county to the Romans. During the Roman era roads and ports were constructed throughout the county and farming was widespread. What are the answers to this following set of questions: 1. When did the first people live in Norfolk?
2. Where in england is it?
3. Does it have coastline?

Michelle Obama has just started a campaign against childhood obesity with the admission that she put her girls Malia and Sasha on a diet because they were getting fat. Clearly, childhood obesity must be solved urgently. But is it a good idea for mothers to put their daughters on diets? Studies show that the more children diet, the more likely they are to become obese as adults. Research also shows that girls are highly influenced by their mothers when it comes to eating habits and body image. This was the case for Carly, 40, who blames her mother for her lifelong struggle with weight. "My mother was on a diet the whole time I was growing up," she says. "And she put me on my first diet when I was 10. I lost puppy fat, gained her approval and never ate normally again." America's First Lady clearly has a vital healthy eating message to convey. But could this be damaging for Malia and Sasha? Could they develop eating disorders because of it? "It's wrong just to blame mothers for their daughters' eating disorders," says Susan Ringwood, chief executive of the eating disorders charity. "There is a genetic component to eating disorders." However, "We do know that parents have a very strong influence over a child's eating. It's important to realize that you are your daughter's role model. Girls idolize their mothers." says Ringwood. "No food should ever be 'good 'or' bad'," Ringwood says. Instead, "You have to make it clear that food is a sociable, healthy and fun part of life, not something to be feared." "Talk to her about body image," Ringwood says. "Talk about how curves are an important and exciting part of being a woman. Show her that anorexic ) fashion models are not sexy, but ill. The pressure on girls today is immense," she says. Never forget that you are the authoritative voice, too. What are the answers to this following set of questions: 1. Who are Michelle Obama's girls?
