Because your motor is spinning faster at higher speeds causing higher rpm's
check egr valve
Probably a matter of where the engine's power band is set out, or you may simply be bogging the engine down at lower speeds. Try downshifting and keeping your RPMs up a little.
lower rpms use less gas higher rpms have more power
That depends on what your rear end gear ratios are. It varies greatly. As a default, you typically upshift at 1500 RPMs and downshift at 1000 RPMs.
You most certainly do, it is called overdrive. You may be able to achieve high speeds in 4th gear, BUT you can also acheive those speeds in 5th gear but with lower RPMs, thus resulting in an increase in fuel economy
Fast speeds on a hard drive are important if the drive is going to used for gaming. The average speed of a hard is around 7500 rpms. If it is being used for gaming, a faster hard drive with speeds of upto 10000 rpms should be used.
major vacuum leak?
2-3 rpms

The copper jacket is needed to push bullets at very high speeds and to withstand the very high rpms generated by the rifling. A lead bullet would fly apart because it is too soft. The harder copper jacket keeps the bullet in one piece.
