How do you calcuate height of instrument in surveying?
When surveying using a "level" instrument , the "level" instrument is set-up and adjusted to level by adjusting the screws. When surveying you have an instrument person and a rod person. When trying to find the height of the instrument, the rod person places there rod over a "known" elevation, either a benchmark or a temporary benchmark that has a known elevation. To get the height of the instrument, you need to "shoot" the level to the rod person holding the rod on the known elevation, this is called the "Backsight". This elevation will be read by the instrument person, and recorded in the survey field book. This value backsight elevation will then be added to the known elevation of the benchmark or the temporary benchmark, to get the height of instrument. HI = known elevation + BS Height
What is the height of a soundwave which indicates loudness of a sound?
It's the Acoustic Definition of Amplitude.The height of the sound wave is called its amplitude.
Which instrument would a meteorologist use to measure the height of clouds?
The ceilometer instrument.

A heightometer.

What is the average altitude of a airplane?
50km in height
How can air tell the height of a mountain?
With the help of an instrument called barometer, you can tell approximately the height of a mountain, but you must climb to the top of the mountain to use such instrument. The higher is the mountain, there is less on the top of it, so the air pressure is fewer over there.
Which instrument is used for measuring altitudes in aircraft?
An altimeter is the instrument that is used for measuring altitudes in aircraft. It indicates the height above a reference point, typically sea level, and provides crucial information for pilots to maintain safe flying altitudes.
Which instrument would a meteorologist use to measure the height of clouds?
The ceilometer instrument.
How high is the average height to jump out of an airplane?
13,000 ft.
Do you need to know the height of an airplane to determine speed of that aircraft?
No.
What instrument measures the height of a soda can?
A ruler.
What instrument measures the height of a desk?
A heightometer.
An airplane is sighted at the same time by two ground observers who are 4 miles apart and both directly west of the airplane They report the angles of elevation as 13 and How high is the airplane?
To find the height of the airplane, we can draw a right triangle with the two observers and the airplane. The distance between the observers is 4 miles, so we can use trigonometry to determine the height. Using the tangent function, we can set up the equation: tan(13 degrees) = height / 4 miles. Solve for height to find it is approximately 1.12 miles.
