Answer:
Dear people in Westfield,
your pipes contain rust because of a chemical reaction on the iron you use.The problem could be fixed by using strong plastic pipes as that takes a long time to degrade.The rust is produced when water and air mix with the iron.it takes time for the pipe to rust but that is the problem
as I said before,try using plastic pipes that are resistant to pressure.you could get them at home Depot or other pipe production company's.
Sincerely,

Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemo-synthesis). Heterotrophs cannot synthesize their own food and rely on other organisms, both plants and animals for nutrition. hope this helps :)
Answer:
1. Gravitational potential energy is the energy that an object has because of its height and is equal to the object's mass multiplied by its height multiplied by the gravitational constant (PE = mgh). Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point.
2. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2). Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
3.Initially, before the big bang, the universe-ball was at rest. Now, after the big bang, it is falling: light and matter exist, and they are moving. And yet, because of the negative energy built into the gravity field created by these particles, the total energy of the universe remains zero.
4. When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
5. When the skater is dropped onto the ramp from above, the potential energy decreases and the kinetic energy increases. Every time the skater bounces from the impact, thermal energy is gained, and both potential and kinetic energy are lost.
Answer:
A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign - make good reference points.
