What type of electronic probe could be used to determine the pressure inside a balloon?
A barometer.
What is the instrument used to determine air pressure is called?
The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with mercury that it turned upside down into another container filled with mercury.
What is barometric pressure measured by?
A barometer measures atmospheric pressure to determine weather or altitude changes.
What is the instrument for weather?
Barometer (barometric pressure) Thermometer (temp) & rain guage (amt of rainfall in inches)
Can an odometer be used to determine the altitude of mountains?
An odometer is for distance travelled, not height. You need something sensitive to changes in atmospheric pressure, a barometer, for measuring altitude. Altimeters as fitted to aircraft are in effect barometers.
How do you think science is used by firefights?
Firefighters use science on a daily basis. Here are a few examples:They use chemistry to determine the best ways to extinguish fires.They use Biology and medical science to treat people with medical emergencies.They use meteorology to determine how the weather will affect wild fires.

How do you determine the height of an object from free fall?
If the object that falls is sufficiently dense and streamlined, so that the effects of air resistance can be neglected, then you can estimate the height from which it fell like this: -- Time the fall, from the instant the object is released until the instant it hits the ground. -- The distance it fell is [ 16.1 T2 ] feet, or [ 4.9 T2 ] meters. The height of a tall building can easily be measured by using a barometer. There are two convenient methods. 1). Drop the barometer from the roof of the building. Time its fall, from the instant the barometer is released until the instant it hits the ground. The height of the building roof is [ 16.1 T2 ] feet, or [ 4.9 T2 ] meters. 2). Tie the barometer to the end of a long tape-measure or rope. With the barometer as a weight to resist the inaccuracy that would be introduced by the wind, slowly pay out the tape or the rope from the edge of the building's roof, until the barometer just touches the ground. At that point, either read the height directly from the tape, or mark the rope where it touches the roof, and measure the length of rope between the barometer and the mark later.
What is the objectives studying of agriculture meteorology and climatology?
To determine the crops which can grow.To decide the time period of cultural practiced.(making lands, planting or seeding, fertilization, watering, adding insecticide & weedy side, harvesting)To predict rain fall.To create improved varieties which can tolerate against weather condition.To determine soil conditions.
What tools are used by climatologists?
Climatologists use a wide array of tools to determine long term trend and patterns in weather. Some of these tools are the barometer, hygrometer, thermometer, computer based models, ice cores, and tree rings.
Why do scientist fly into hurricanes?
They have a barometer and other instruments when they fly into the hurricanes to figure out the pressure and other readings. Wind measurements are used to determine what category a hurricane is. These measurements can be used to help determine structural features withing the storm and can be used in combination with data from satellites and, in some cases, ground-based radar to make predictions about a storm.
How can you determine air pressure?
Air pressure is usually measured using a barometer. This device usually has mercury inside it along a tube that is a compete vacuum. As the air pressure rises the pressure of the air pushes down on the mercury and forces it to rise further into the vacuum. 760 mm of mercury is considered to be 1 atmosphere. For very high pressures an aneroid barometer is used. This has wafers inside that are compressed under high pressure that give a reading.
