How to remember things before a test?


I have a physics test tomorrow and I'm the tenth grade, any tips?I've finished stuying though.

Go over your notes one more time right before bed tonight. Get a good night sleep and have a healthy breakfast tomorrow. That is the best way to score well- as long as you have already studied.

Farcry 2 Editor, physic test

Simple physic test (Level 1)?


After the aquaduct test which tricked most of you, this is a much simpler one

If a 3kW Microwave oven has 95% efficiency
How many seconds will it take to boil 200ml of water

The water is initially at ambiant temperature at 24°C
The experiment is made at normal atmospheric pressure

Assumption: no loss of energy in or through the receipient.

Please provide demonstration to get your 5 points.
This is basic physic and can be resolved through two equations.
AND MAKE SURE YOU USE THE RIGHT UNITS IN YOUR FORMULA!

3kW = 3,000 joules per second

3,000 joules x 0.95 = 2,850 joules per second

Delta T = 100C - 24C = 76C

200ml of water = 200grams of water

Specific heat of water = 4.184 j/g-C

Latent heat of vaporization of water = ~2,250j/g at sea level

Total energy needed to raise the temperature to 100C:

Q = mc(delta T) = 200g(4.184j/g-C)(76C)

Q = 63,596.8 joules

Total energy to boil 200g of water at 100C:

Q = m(LHV) = 200g(~2250j/g)

Q = 450,000 joules

A total of 513,596.8 joules

513,596.9 joules / 2,850 joules per second = 180.2 seconds

~3 minutes

simple physic test (home made)?


A 15 Tonnes boat is about to go through a deep aqueduct which can stand the weight of 20 cube meter of fresh water. The aqueduct is already 74% of its weight capacity with the water it supports..

what happens when the boat stand above the aqueduct ?
A. The aqueduct collapse under the weight
B The bridge is OK and the boat goes through
C The boat get stuck

The first one to provide the right answer gets his 4 stars rating
please provide justification for your answer
The answer was C and the best answer came from in the Engineering section of this website.

AP Physics is it calculus based and can you just take part of the ap test?


I am trying to figure out the different types of ap physics tests, like B C and CEM and I am not sure what is in them and if they are algebra or calculus. Can you take just one part of the test, like B or C or do you have to take all of it?
Thanks

It depends on the class you are taking. If you take the AP Physics B course, you will take the B exam at the end of the year. Consequently, if you take the AP Physics C course you will take the C exam.

AP Physics C is calculus-based, not B, but you must have a good pre-calculus background (trig).

How hard was the SAT II Physics test???


I'm taking the SAT II PHYSICS test this Saturday, and just wondering, how hard is it? Do we have enough time do finish all of it?

You definitely have enough time to finish it if you've studied it enough. I'd say personally, it was a lot harder than I thought it'd be, but that's also because I'm in AP Physics B and AP classes have a whole different method of teaching.

SAT II Physics tests you a lot on just do you know this fact or do you not. Equations aren't given so that was a bummer for me. I used Barrons and I think it helped me quite a lot with all the terms and all. Definitely in general though, it was not too bad.

Good luck on your test!
