Water is standing in the crater or if subsurface material is unsuitable to fill the crater
In this case, a controlled low-strength material (CLSM) is typically used. CLSM can be poured into confined spaces and will harden into a stable material that can support loads. It is often employed in situations where subsurface debris is present but filling with traditional materials is impractical.
A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.
A HID ballast can be purchased from Amazon or eBay. The term 'ballast' is used to describe large inductors used to limit AC current for fluorescent lighting.
fluorescent lamp work on the principle of ionizing the gas , which requires very high potential difference . this excess voltage is provided by the choke coil . when the starter breaks the circuit , current suddenly drops , thus to maintain the current the choke coil a very high voltage is supplied by the choke coil . this very high voltage cannot be obtained from a resistor or a rheostat , since it being a linear element , thus it cannot be a replacement for choke.
No, it is not recommended to run a 50 watt halide bulb on a 100 watt halide ballast. The ballast should match the wattage of the bulb to ensure proper operation and to avoid potential damage to the bulb and ballast. It is best to use a ballast that is rated for the wattage of the bulb being used.

Yes
Yes
Yes
That is a ballast tank used to alter the angle of the submarine up or down
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
That is called ballast. Ballast is used to support the railroad ties.
Ballasts are not used with motor control.
On occasion, ballast is required to bring the centre of gravity within operational limits. There are two methods of carrying ballast: - Ballast (hold loaded) -Ballast fuel: the fuel used for this purpose is called ballast fuel. Trapped Fuel:The fuel in an engine or fuel system that is not in the fuel tanks
Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.
