Question: Modern roller coasters have vertical loops like the one shown in the figure. The radius of curvat... Give your answer in meters. If it actually starts 3 m higher than your answer to the previous part (yet still reaches the top of the loop with the same velocity), how much energy, in joules, did it lose to friction? Its mass is 1100 kg.

It may compare favorably to a low dipole ("all" dipoles are low on 160 meters) simply because, in many cases, low dipoles don't get out very well. It may even be possible to work DXCC with an HWV. We know that doesn't prove high efficiency because KH6DX has achieved 160m DXCC operating mobile.

Definition of Vertical Velocity. For instance, if you move 30 meters in 10 seconds, then your velocity is 30 meters divided by 10 seconds, or 3 meters a second. Velocity is a vector quantity, so we must specify the magnitude of the velocity, which indicates the size, and the direction of the velocity, which indicates where it is going.

Motorized vertical stages provide automated smooth and stable height adjustment. They can be added to linear stages to create xz, and xyz stage stacks for various positioning requirments in industial and scientific applications.

Notice that there is a LOT of vertical radiation with this installation. This might explain why so many people think 40 meters is a good local band instead of a DX band. Such antennas are better suited for NVI than DX. An 80 meter antenna at 3050 feet would be even worse in this regard, as it would be even lower mounted in terms of wavelength:
