A firefighter mounts the nozzle of his fire hose a distance 38.5 m away from the edge of a burning building so that it sprays from ground level at a 45° angle above the horizontal. After quenching a hotspot at a height of 9.45 m, the firefighter adjusts the nozzle diameter so that the water hits the building at a height of 19.5 m. By what factor was the nozzle diameter changed? Assume that the diameter of the hose stays the same, and treat the water as an ideal fluid.
They sniff to see what other dogs were there and peed on it. And then they pee on it to put their scent on it.
For fun mostly - but the others are right - to see and ID other dogs.
if you pulled fire alarm not a big deal why u r taking tension?it's just a mistake my brother pulled a fire alarm in a public library by mistake they didn't do anything to him they just call fire department to come and fix it it's just a mistake so go and take some water nobody is gonna say anything and nobody even cares about a fire alarm.
Call the fire department and ask them. They may send someone out to give the apartment building notice or a fine.
They're checking to see who else peed there. peeing for dogs is a way they mark their territory, but can also be a way that they can convey information to other dogs. Usually dogs can tell the relative age, health and size of the animal from its urine. Then your dog adds his scent/message to the area.
