# Content Science Questions

I have a couple of questions that I could use help in answering if anyone could lend me a hand it would be greatly appreciated.

900 kj is applied to 50g of aluminum, what is the specific heat?

Snowboarder traveling 14m/s jumps a ramp, what is the max height?

Pendulum length L & period T, the length increases to 2L, what is T?

5kg car collides head on with an identical car at rest, 1st car comes to a stop, what happens to the 2nd car?

I realize some of the questions seem vague, but this is how they appear on the test?
Thanks

Hi brute25! Welcome to PF!

Pendulum length L & period T, the length increases to 2L, what is T?

What have you tried? What equation do you think would help?

I'm not real sure.
I'm taking the texes exam to become a science teacher in texas and this question was on the test.
My strengths are in anatomy & biology.
Is there a goog website to look up the equation?
Thanks

ah … I think you need a good book which covers the whole of physics rather than a few websites to answer individual questions.

To be a Texas science teacher, you presumably need to know a lot more science than you do at present.

To deal with the questions you asked:

a] wikipedia "specific heat".
b] you ned to know formulas for uniform acceleration
c] wikipedia "pendulum"
d] momentum is conserved in all collisions

But this is a patchwork approach … not very appropriate for a big career step.

I suggest you start a thread in the Academic & Career Guidance forum (click https://www.physicsforums.com/forumdisplay.php?f=139"), where more people who can help will see it, and explain what Texas expects of you (and when), and what your personal history is, re physics and maths.
