Why do we observe fountains of water coming out of the leaking joints or holes in pipes supplying water?
Water fountains from leaking joints or holes in pipes happen due to the pressure within the pipe. When there is a leak, the water under pressure escapes through the opening, creating the fountain effect. The size of the leak and pressure inside the pipe determine the height and strength of the water fountain.
What is the example where Acceleration against the direction of motion?
When acceleration is opposite to (against) the direction of motion, the magnitude of the velocity decreases, meaning that the object slows down. An example is the application of the brakes to slow or stop a car. During the time that the pressure remains on the brake pedal, the car's acceleration is negative ... meaning opposite to the direction of motion ... and the car's speed is decreasing.
The ultimate source of energy for weather is the?
The ultimate source of energy for weather is the Sun. Solar radiation drives temperature differences and provides the energy that fuels atmospheric circulation, ultimately leading to weather patterns around the globe.
What happens if velocity decrees or increases?
If velocity decreases, an object's speed is decreasing. This could mean the object is slowing down or coming to a stop. If velocity increases, the object's speed is increasing, indicating it is moving faster.
What does a negative acceleration indicate about an object?
A negative acceleration indicates that the object is decreasing in speed or changing direction in the opposite direction of its current velocity. It could be slowing down, coming to a stop, or changing its movement trajectory.
When the barometer is dropping what is the air pressure doing?
increasing
What shows falling pressure stormy weather might be coming?
barometer
What weather variable willl decrease when a storm is coming?
Air Pressure
What weather do you think is coming when air pressure is rising?
When air pressure is rising, generally clear and dry weather is expected. Rising pressure indicates a stable atmosphere with sinking air, which typically means calm conditions with minimal chances of precipitation.
What will the weather be like when air pressure is rising?
When air pressure is rising, it means that a high pressure area is coming in your direction. High pressure areas tend to bring very sunny and calm weather so the weather should improve when the air pressure is rising
When you see a drop in air pressure what kind of weather is coming?
snow or rain
What does a falling barometric reading (atmospheric pressure) indicate?
A fall in atmospheric pressure - an approaching storm system.A:A barometer measures air pressure: A "rising" barometer indicates increas­ing air pressure; a "falling" barometer indicates decreasing air pressure. A:Lower pressure, more clouds, and less fair weather.
How do you tell if leaking antifreeze is coming from the engine or the radiator on a 1996 Buick Regal 3.8 engine?
Pressure test system to observe leak
If stormy weather is approaching the pressure tendency probably be?
Barometric pressure decrease indicates coming stormy weather, rain, wind, , heat. Barometric pressure rise indicates fair, dry, colder weather. Slow, regular and moderate fall in pressure indicates low pressure area is passing at a distance. Any marked change in weather unlikely. Sudden decrease, even if small, indicates a nearby disturbance; normally bringing wind, and short showers. Large pressure drop signals a coming storm in 5 to 6 hours. Large, slow and sustained decrease indicates a long period of poor weather. Coming weather will be more pronounced if pressure started rising before dropping. Sudden rise of pressure,when the pressure is about average or above average and the weather is fair, indicates approach of a low pressure cell, and the barometer will soon start to come down. Rapid rise when the pressure is low, announces a short period of fair weather. If pressure rise is large and prolonged, count on a many days of good weather ahead.
What is the significance of the barometer?
The barometer measures air pressure. Its main usefulness is when the pressure is rising or falling. If you are in a house with a basement and the sky looks ominous and you suddenly see the gauge on the barometer decreasing, it means that the air pressure around your house has started falling fast. It also means you should get into your basement as fast as possible so you will avoid the tornado that will blow your house away. A falling barometer indicates stormy weather is coming. A rising barometer indicates fair weather is coming. With satellites and weather reports we have less need for barometers except during severe storms when we most need such reports.
What Weather instrument indicates a storm is coming?
In order to know that a storm is coming, you need to know the air pressure. Storms are normally associated with a Low Pressure System. A Barometer can be a tool you can use to predict an oncoming storm.
Why Perhaps more than any other single measurement atmosheric pressure is the best indicator of current and changing weather conditions?
The atmospheric pressure is the best indicator of current and changing weather conditions, because low pressure will indicate clouds and storms coming. High pressure indicates that clear skies and sunny weather are to come.
