I got a $100 parking ticket for parking in front of a fire hydrant while visiting my mom.(The freaking hydrant was in someone's yard, about 5 feet into their front yard covered with plants!!!!)My car is registered from NY State. I tried to pay online and it states that the ticket has already been paid. I know for a fact that I didn't pay it!I just looked up the website:
The classes that you refer to are the classes of fire that an extinguisher can be used on, not the type of fire extinguisher. All extinguishers except for water can be used on multiple classes of fire. Class 'A' Solid combustible materials (wood, paper, textiles etc..) Class 'B' Flammable liquids (petrol, diesel etc..) Class 'C' Flammable gasses (Propane, butane, natural gas etc..) Class 'F' Combustible cooking media (oil, fat etc..) Electrical Electrical Appliances ( TV, toaster, fuse box etc..) Generally speaking; Water can be used on class 'A' Foam can be used on class 'A' and 'B' Dry Powder can be used on class 'A', 'B', 'C' and Electrical CO2 can be used on class 'B' and Electrical Wet Chemical can be used on class 'A' and 'F' To answer your questionThe fire was class 'A' so water would be the correct extinguisher to use. Personally, I would use the water first, then if it were still alight I'd use the Foam. Hope this helps!
Gravity is a propery of mass So, the Earth's mass is what generates gravity. Your body, also, will do the same thing. As you move away from the Earth, the gravitational pull weakens. In deep space, there's no mass around to produce gravity.
