without dealing with temperature issues, gasses, lava, etc. (Remember, it is a question about gravity) If you were able to drop a golf ball down the hole, wouldn't the gravitational pull force it to speed to the center of the earth then pass the center, slow up, eventually return to the center,and float in the center point, or what? Does my description make sense and what do you think would happen? I'm no rocket scientist but this is a question I've been pondering for awhile.

Suppose there is an object on top of a smooth surface (frictional force=0). If we give the object a horizontal push, it would normally move forward. But according to Newton's Law on acton and reaction force, when I give the object a push, a force with the same magnitude but opposite direction will exert back on me, and hence the object stands motionless. Is this correct? If not, why?

which of the following 4 discoveries would you like to see in the future ? Please explain in detail as to why you may think it to be the case !

A) the medical cure to ALL illnesses. ( NOT to be confused with immortality ! )

B) fusion energy- the FINAL solution to the energy problem. will provide humanity with limitless energy forever.

C) intersellar travel - the ability to traverse long distances in a lifetime and thus achieve contact with other life forms and facilitate the spread of humanity thru the universe.

D) the explanation of consciousness - a way by which humanity will take a new direction by transcending current science into a newer "meta-science", a tricky question, one that holds the promise of ending ALL other questions or one that has no answer

and open you eyes to the truth that we are blind to the real world,
a world not built of particles, but waves....

Hey everyone! Can someone please help me with this physics problem? Thanksssss much!!!! :]

Marble A, mass 5.0 g, moves at a speed of 20.0 cm/s. It collides with a second marble, B, mass 10.0 g, moving at 10.0 cm/s in the same direction. After the collision, marble A continues with a speed of 8.0 cm/s in the same direction.

a. Calculate the marbles' momenta before the collision.
b. Calculate the momentum of marble A after the collision.
c. Calculate the momentum of marble B after the collision.
d. What is the speed of marble B after the collision.

Two pieces of the same wire have the same length. From one piece, a square coil containing a single loop is made. From the other, a circular coil containing a single loop is made. The coils carry different currents. When placed in the same magnetic field with the same orientation, they experience the same torque. What is the ratio Isquare / Icircle of the current in the square coil to that in the circular coil?

I'm performing an experiment and a need to be able to create about a 500 psi pressure environment. I have a container (iron vessel) that I know is capable of holding such pressure, but I don't know how to create it.

Most air pumps don't go higher than 100-150 psi. I considered a carbon dioxide tank for paintballing, but they only go up to 300 psi. Any ideas?

I'm having quite a bit of trouble setting this problem up. I know I need to use the equation B= [(4pi x 10^-7)(current)]/(2pi x radius), for both A and B and add to get the magnitudes, but I have no idea what numbers to plug (i.e. the radius) to get 2 equations for each to add. Can anyone offer me some guidance/assistance? Thanks in advance.

Two long, straight wires are separated by 0.12 m. The wires carry currents of 5.5 A in opposite directions, as the drawing indicates.
