I am asking this because, everything is supposed to have a corresponding particle in the "anti" world. So even graviton should have "anti-graviton".......

Normally gravitation would happen because of exchange of 'gravitons'.

Now between matter and anti-matter, 'gravitons' and 'anti-gravitons' are being transmitted and of course these cannot be exchanged right?

so now there must be no gravitational attraction between these?

Consider a projectile fired vertically in a constant gravitational field. For the same inital velocities, compare the times required for the projectile to reach its maximum height (a) for zero resisting force and (b) for a resisting force proportional to the instantaneous velocity of the projectile.

If u could time-travel and go back to the past, and then u got killed while u were visiting the past, how is it that u existed at all in the present? or if u killed ur own grandparents in the past, how would still have been able to exist to do that in the first place?

Strictly speaking, does a car burn more gasoline when its lights are turned on? And does the overall consumption of gas depend on whether or not the engine is running?

Anything can be divided infinitely, including a second. So aren't we then moving through an infinite amount of time every second?
How can that be?

The CERN Courier states that creating nano-blackholes (NBHs) is safe because higher energy collisions happen naturally. If one considers the conservation of momentum, wouldn't thusly formed NBHs have to either absorb relatively enormous amounts of mass to stay with the earth, or always rapidly move through the earth and escape?

Isn't their argument for safety therefore invalid, since they either must grow so fast thet they'd swallow the earth in short order or they simply couldn't stay to begin with (as CERN created NBHs would)?

A car is travelling at 60 MPH when its brakes are fully applied, creating a constant deceleration of 22 ft/sec. Find the distance covered by the car before it comes to a stop. (Note 60 MPH=88 ft/sec.) I want to just say that it will take 4 seconds to stop(since 22x4 is 88) and then plug that into the distance=vt formula, but I know this isn't right. I am supposed to use antidifferentiation in some way. The question is multiple choice, so here are the choices:

A)172 ft
B)176 ft
C)174 ft
D)180 ft
E)178 ft

A. How far will a freely falling object fall from rest in five seconds? six second??
i got for 5 sec 25 meters, and for 6 sec 30 meters. Is this right? If not please explain.


B. How far will an object move in one second if its average speed is 5m/s? Is it 5 meters??? i could be wrong
thanks for help!

All these wars going on in the world - people getting killed every single day - has any nation or person managed to develop shield technology - somethings in sci fi have been achieved in reality - what about this one - shields - if you could develop a technology that would repell the bullet or bomb then you wouldn't need to defend yourself by attacking someone before that can attack you ! Is it coming soon? Is it in development now? Because it can't come soon enough - to prevent all this carnage !

When i listen to music on my hi-fi (which is connected to my pc)
the sound changes whether my light is on or off.
Its seems that the sound level rises as my light is turned off.
I have a theory that it could be because the light waves interfear with the sound waves.
Therefore if there is no light, then sound will distort less.
But---- you will normally turn off your light in a room when your to go to bed. so is it possible that my brain believes that im going to sleep so it rises my sense? or something similar to this.

I would like to hear what you think~

If you had one positive charge +q1 and one negative charge -q2 and suppose we place a third charge along the line between the two charges. Zone 1 is left of the positive charge. Zone 2 is between the positive charge and the negative charge. Zone 3 is right of the negative charge. This third charge can be in equilibrium if the electric force from the positive can balance the electric force from the negative charge. Than how would you consider the following statements??

True or False -- A negative charge placed in Zone 2 can be in equilibrium.

True or False -- A negative charge placed in Zone 1 can be in equilibrium.

True or False -- A positive charge placed in Zone 2 can be in equilibrium.

True or False -- A positive charge placed in Zone 3 can be in equilibrium.

True or False -- A negative charge placed in Zone 3 can be in equilibrium.

True False A positive charge placed in Zone 1 can be in equilib

It is common these days to see news stories about how to save fuel by changing your driving habbits. One of the main ways is to "avoid rapid starts and stops." I can see why rapid starts require more energy, but how does stopping the car briskly also use more energy?

Whether the car's momentum is lost through friction with the air and engine, or through friction with the brake pads, I can't see how it would make any difference.
