Hello,

Astronomors and scientists often refer to the Big Bang theory when they attempt to explain the creation of the universe. Generally, all matter was in "one tiny place," and then the matter was blown outward in an incredible explosion to create the universe.

My question is this: Describe the matter before the Big Bang occurred. In other words, of what substances did that matter consist? How did all of that matter end-up in "one tiny place" before the Big Bang occurred?

Thank you.

Sincerely,
D

I know that if you have x to the power of two + x to the power of 3 it would be x to the power of 5. If it was x to the power of 2 x x to the power of 5 would it be 2x to the power of ten?

Recently our physics class tried an experiment in class where we measured impulse by having a cart slide off a basically frictionless ramp that's inclined. The cart hits a spring which is attached to a force sensor. We let the cart collide, and then stop the cart and watch the force sensor record the force vs. time graph.
We get the usual impulse peak, but immediately after that there are some really small bumps on the graph, and after that the graph levels out and has a slope of 0 again.
What do these bumps indicate, because this is happening after the cart has already gotten off the spring? How does this affect the momentum of the system?

Is log10Z the same as logZ??

also if someone plots log10Z instead of lnZ, would it affect the value of m from the equation lnZ= mx +c

These are some that have stumped me. Feel free to try any yo ucan. How do you find the position formula if you just have the velocity? Thanks

A projectilve is fired straight upward with a velocity of 400 ft/sec.
What is the position formula?
Find the time and the velocity when it hits the ground
Find the maximum altitude achieved by the projectile
Find the acceleration at any time

A point is moving on a coordinate line has position function s(t)=t/\3-9t+1 on [-3,3]
Find the velocity at time t
Find the acceleration at any time
When is it moving to the left?
when is it moving to the right?
When is it stopped?

A projectile is fired directly upward with position s(t)=100-192t-16t/\2
Find the velocity?
Find the acceleration?
Find the maximum height?
Find the duration of the flight?
When is the velocity zero?
What is the intial veloctiy?
What was the speed at impact?
