True, they have zero electrical resistance.
The approximate speed of sound in dry (0% humidity) air, in meters per second, at temperatures near 0 °C, can be calculated from
![c_{air} = (331.3+0.606 \upsilon)](https://tex.z-dn.net/?f=c_%7Bair%7D%20%3D%20%28331.3%2B0.606%20%5Cupsilon%29)
Here
Temperature in Celsius
Replacing with our values we have that
![\upsilon=58\° C](https://tex.z-dn.net/?f=%5Cupsilon%3D58%5C%C2%B0%20C)
![c_{air} = (331.3+0.606*58)](https://tex.z-dn.net/?f=c_%7Bair%7D%20%3D%20%28331.3%2B0.606%2A58%29)
![c_{air} = 366.1m/s](https://tex.z-dn.net/?f=c_%7Bair%7D%20%3D%20366.1m%2Fs)
Therefore the speed of sound in air at that temperature is 366.1m/s
Answer:
The axial region of the body consists of the bones of the head, trunk of a vertebrate, skull, vertebral column, and thoracic cage. The human skeleton consists of 80 bones.
Explanation:
The axial region of the body consists of the bones of the head, trunk of a vertebrate, skull, vertebral column, and thoracic cage. The human skeleton consists of 80 bones.
It is composed of the following six parts:
1. Skull (22 bones)
2. Ossicles of the middle ear
3. Hyoid bone
4. Rib cage
5. Sternum
6. Vertebral column
The axial region of the body forms the vertical axis of the body as the axial skeleton supports the head, neck, back, and chest.
Answer:
option D
Explanation:
Sunspots are the spot that appears on the sun, this spot appears darker than the surrounding surface of the sun.
Sun magnetic field goes through a cycle and this cycle is called the Sunspot cycle. Every 11 years the magnetic field of the sun completely flips. This sunspot cycle affects activity on the surface of the sun.
Sunspot cycle is the pattern of solar activity where an average number of sunspot gradually increase and decrease.
Hence, the correct answer is option D
