If all other factors, such as medium, are kept the same, longitudinal waves tend to be stronger.
Answer: Transverse
Explanation: Transverse waves possess a vertical wave motion and a horizontal particle motion.
Answer:
Radius, r = 0.00523 meters
Explanation:
It is given that,
Magnetic field, 
Current in the toroid, I = 9.6 A
Number of turns, N = 6
We need to find the radius of the toroid. The magnetic field at the center of the toroid is given by :

r = 0.00523 m
or

So, the radius of the toroid is 0.00523 meters. Hence, this is the required solution.
Meters Micrometers centimeters millimeters
