Europa's gravity is approximately 13% of Earth's. The temperature on Europa varies from −160 °C at the equator, to −220 °C at either of its poles. [145] Europa's subsurface ocean is thought to be significantly [clarification needed] warmer however. It is hypothesized that because of radioactive and tidal heating (as mentioned in the ...
Using 32 mm (1.26 in) - 0 gauge - track, there is an extensive range of 16 mm to the foot scale [1:19] live-steam and other types of locomotives, rolling stock and accessories. Many of these models are dual gauge, and can be converted to run on 45 mm ( 1.772 in ) track ( gauge 1 ), and radio control is common.
In a local model train store he came up with the idea for the world's largest model railway. [7] Back in Hamburg, he searched for email addresses online and started a survey on the popularity of real and fictional sights of the city. In the process, the Miniatur Wunderland, which did not yet exist, was ranked 3 by male respondents.
The plastic track had two such lanes, and cars could change lanes with the flick of a switch on the controller. TCR sets came with "jam cars", a slow moving drone which both racers had to avoid crashing into. Like Matchbox's Powertrack, some cars featured lights. The first sets consisted of up to 4 Formula 5000 cars. The track (which stayed the ...
A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. [1] The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track. The forces experienced by the rider are constantly changing ...

Mini-Z with a Lamborghini body. Mini-Z is a brand name for a popular line of 1:28-scale electric radio-controlled cars manufactured by Kyosho Corporation, a Japanese manufacturer of various radio-controlled devices. Kyosho makes a huge number of bodies [1] for the Mini-Z. The wheelbase can range from 86mm to 106mm.
The zonal and tesseral terms for n = 1 are left out in . The coefficients for the n=1 with both m=0 and m=1 term correspond to an arbitrarily oriented dipole term in the multi-pole expansion. Gravity does not physically exhibit any dipole character and so the integral characterizing n = 1 must be zero.
