Answer:
= 0.55 m
Explanation:
A standing wave is characterized by anti-nodes and nodes.
Antinodes are points on a standing wave at maximum amplitude, while nodes are points on the standing wave that are stationary and have zero amplitude.
The distance between two adjacent nodes or two adjacent anti-nodes is equivalent to half the wavelength.
Therefore, in this case the half wavelength is 27.5 cm.
Thus, wavelength = 27.5 × 2
= 55 cm
<u>= 0.55 m</u>
Answer:
8.5 m/s
Explanation:
please see paper for the work!
Answer:
The length is 
Explanation:
From the question we are told that
The frequencies of the two successive harmonics are 
, 
The speed of sound in the air is 
Generally the frequency of a given harmonic is mathematically represented as
Here n defines the position of the harmonics
Now since the position of both harmonic is not know but we know that they successive then we can represented them mathematically as
and
So
=> 
=>
Maps and Globes share the following features:
Both are scale Models.
Explanation:
A globe is a scale model of the Earth that presents the most accurate depiction of geographic information such as area, distance, and direction.
A map is a two dimensional representation or a drawing of the earth’s surface, or a part of it, on a flat surface, according to a scale. Thus it is also a scale model.
A globe differs from a map. It is a three dimensional sphere representing the whole Earth.
A map is usually used to represent a specific part of the Earth and is used for Navigation. It has details and symbols. However, a globe can not be used for such details.
A globe can be used to get a broad-level picture of the world.
