<p>i think you're good to go if you are aiming for 750+. but if you want only an 800, i'm not too sure. that was my scores (more or less) in my practivces.</p>
<p>btw...are the topics( or moreover..the information) in the pr book enough for the actual test?meaning...if I know all of that, will I manage? cause although the sat requires knowledge in so many Physics chapters, the information in the prep books are so vague...it's only the elementary stuff.</p>
<p>three ice cubes are placed into equal beakers
ice cube 1 = 50g mass
2 = 75 g mass
3 = 100 g mass</p>
<p>after the cubes are placed in the water, the beakers are filled to the brim with water.</p>
<p>After all the ice cubes melt, which of the following is most likely.</p>
<p>A. All beakers have overflowed
B. No beakers have overflowed
C. Beaker w/100 g ice has overflowed.
D. Beaker w/ 100g and 75g of ice has overflowed
E. Beaker with 50 g ice has overflowed</p>
<p>the answer is B</p>
<p>since water is less dense as a solid then a liquid. So the water level will lower a bit.</p>
<p>Do we need to know th exact names of gas laws, such as charles law, boyles law, and that they are isobaric, isochoric, isothermic, etc... or do we just need to know the relationship between temp, pressure, and vol of an ideal gas. thanks</p>
<p>Does anyone know recent curves for physics sat 2.</p>
<p>thanks again</p>
<p>I am interested in the recent curves too !</p>
<p>just standard relationships and how they relate in graphs and **** lol</p>
<p>and for curves...I would say your best bet is the 10 reals but just to be safe aim at less than 8 wrong. 8 wrong has always gotten 800 (This is including the deducted points...which means 10 raw points of your total score)</p>
<p>heres an easy problem to jump start your spirits</p>
<p>As a variable resistor moves toward a fan in a series circuit the fan runs faster. As it moves away, the fan moves slower. If this resistor is moved all the way near (toward) the fan, what happens in the circuit?</p>
<p>I. fan runs faster
II. voltage decreases
III. current increases</p>
<p>A. I
B. II
C. I and III
D. II and III
E. I, II, III</p>
<p>what the hell kind of a question is this?
its either A or C</p>
<p>yeah its C...its a physics SAT II question lol...anyway anyone know the difficulty of this test compared to the REAL SAT II test in teh collegeboard book?</p>
<p>Another question:</p>
<p>An electron is allowed to freeely move between a pair of parallel plates that have a 1.5 volt potential difference. The electron starts at the negative plate. The velocity of the electron as it strikes the postive plate is most nearly...</p>
<p>A. 7.3 E-8 m/s
B. 7.3 E-5 m/s
C. 7.3 E 5 m/s
D. 7.3 E 8 m/s
E. 7.3 E 11 m/s</p>
<p>explain your answer</p>
<p>and also another one
The reason an observer cannot detect the wave nature of a fast moving truck is
A. The momentum of truck is too large
B. velocity of the wave is too large
C. there are no waves to detect
D. the frequencies is too low
E. wavelengths are too small</p>
<p>explain please..its got something to do with de Brog dude</p>
<p>a good resource for understanding fuzzy concepts</p>
<p>yeah...it is a little like: physics for kids(as far as I've read), but it's quite nice. thanks.(but why does it cover only some of the chapters in Physics?) :(</p>
<p>lol don't ask me...ask the people who made the site haha</p>
<p>by the way, can anyone answer the questions above?</p>
<p>the question with the truck</p>
<p>momentum * wavelength = planck's constant (6.6262 *10^-34)</p>
<p>this question is a little confusing because it could be either A or E</p>
<p>since a large momentum means a small wavelength and small wavelength means a large momentum</p>
<p>even B can be considered valid, but seems a little obscure</p>
<p>for the electron question, i have no clue</p>
<p>(BY THE WAY, what book are these questions from, how hard are they, and is this how hard the real test is?)</p>
<p>these questions are way easier than real test...its from friggen peterson's lol but yeah</p>
<p>whats is the answer to the electron one? please explain</p>
<p>i don't get it, but explanation is...</p>
<p>The voltage of battery is equal to Electrical Potential Energy and the KE is .5mv^2. Set the two equal and you get 1.5 V* q = .5 mv^2. Solving yeilds 7.3 E 10^5 (C), which is velocity as it reaches positve plate.</p>
<p>????????????? lol where the hell did they get that from</p>
<p>thats makes sense </p>
<p>U =qV</p>
<p>and U = KE</p>
<p>however, if this question was on the real test, they have to give you the value of the electron charge.</p>
<p>off the top of my head i think it is 1.6 E-19 C but this value must be given on the exam</p>
