Question:I have to go get my 9th grade physical in a few days. I am a 13 year old girl and I'm NOT sexually active. When I go in a few days I am just going to a normal physical not a gyno appointment. Now I have a few questions.
1. Can anyone give me a step by sep of what is going to happen from the minute I get to the office to the minute I leave?
2. Most likley is there going to be anything uncomfertable?
3. If there is something that makes me uncomfertable do I have the right to refuse??
Please only serious answers!!!!
Answers:I feel that it is important for me to say one thing. You ALWAYS ALWAYS ALWAYS have the right to refuse to let ANYONE do anything that makes you uncomfortable.
When my daughter was younger, a doctor started poking a prodding around without announcing what he was going to do. It made me so angry and it freaked her out.
You could say to the doctor when he/she enters the room, "I'm kind of nervous since this is my first physical. Would you mind telling me what you are going to do before you do it?"
Again, it doesn't matter what uniform a person is wearing, no one has the right to make you feel uncomfortable (in a personal way)...you know what I mean.
Question:An object weighing 16N at the earth's surface is moved above the earth a distance equal to the earth's radius. The gravittional field stength at this new position is..
Earth's radius is 6.38 x 10^6m.
Answer is A. Anyone know how to do this question?
Answers:F* R^2 is a constant F2*R2^2 = F1*R1^2 R2 = 2R1 F2*4R1^2 = F1R1^2 F2 =F1 /4 = 16/4 = 4N The gravitational field strength = Force per unit mass = 4*10 /16 = 2.5N/kg ============================= Or F2*R2^2 = F1*R1^2 Dividing by m g2*R2^2 = g1*R1^2 g2* 4R1^2 = g1R1^2 g2* 4 = g1 g2 = g1/4 = 10/4 = 2.5N/kg ==========================
Question:KEN FOUND A BOX WITH DIFFERENT pieces of metal in the science room.Some of the pieces were magnets,some made of magnets and some were not magnrtic.How can he test the metals and sort them into three categories
Answers:Does he have a known magnet available? If so, magnets will be attracted and repelled by the magnet, depending on whether it's opposite or same poles together. A magnetic metal will be attracted to the magnet regardless of the orientation. The non-magnetic metal will be neither attracted nor repelled by the magnet.
If he doesn't have a known magnet, he should try pieces until he finds a pair that behave like magnets, repelling or attracting, and go from there. If there is only one piece of metal that attracts some other pieces, then it is the magnet. (He could probably devise something to hang the pieces from a string to see which align with the Earth's magnetic field.)

2 the ratio of surface area to __________ puts limitations on a cells size.
3 eukaryotic cells are much larger and have more specialized functions than prokaryotic cells because they contain____________ , which carry out speciallized activities.
4 a cell with a well defined nucleus and cytoplasm surrounded by a plasma membrane is a(n)__________ cell

10 The fluid portion of the cytoplasm is called the _____________
11 Photosynthesis takes place in the ______________ of plant cells.
12 Both plant and animal cells have plasma membranes. In addtion, plant cells are surrounded by a(n) _____________.
Answers:cell theory volume organelles eukaryotic selectively phospholipid organelles ribosomes cytosol chloroplast cell wall * i probably shouldnt be doing this cause you wont learn but thats honestly up to you...
California Standards Tests: Grade 2 English [Questions: 7-9] :The following released test questions are taken from the Grade 2 English--Language Arts Standards Test. This test is one of the California Standards Tests administered as part of the Standardized Testing and Reporting (STAR) Program under policies set by the State Board of Education.
