  The electron and the proton have a negative electrostatic charge and a positive electrostatic charge respectively. Each charge-and the force associated with that unit of charge-is constant-and equal.(The electron and proton have equal, but oppositely polarized, electrostatic charges.) But there is more. The electron and the proton have a negative electrostatic charge and a positive electrostatic charge respectively. Each charge-and the force associated with that unit of charge-is constant-and equal.
The start of life for the tank did not bode well. The first model came off the factory floor on September 8th 1915. On September 10th, its track came off. The same happened on September 19th when government officials were watching.
The first tank was invented by Joseph Hawker in 1827 for military use No it wasn't. Hawker designed a type of caterpillar track, but so did dozens of people in many countries â¦ during the 19th Century and earlier. Hawker's wasn't anything out of the ordinary.iesel fuel is used in most tanks, but newer tanks can run on multiple fuels. The latest innovation in fuel utilization is seen in the M1-Abrams which employs a GE jet engine to power the machine and can run on a variety of fuels from Aviation gasoline to kerosene.
