The answer is convection. There are three main types of heat transfer: conduction, convection, and radiation. Among the three, convection is the one that involves heat transfer through a flowing material or medium. Conduction involves the direct contact between two surfaces at different temperatures, while radiation involves heat transfer through electromagnetic waves.

Answer: 0.625N
Explanation:
Given the following:
Magnetic field Force = 0.25N
Length of wire = 8cm
Current = 3.0 ampere
The force that the same field will exert on another wire 20cm long carrying the same current will be :
Since current 'I' is the same ;
0.25 Force = 8cm
x force = 20cm
Cross multiply:
8x = (20 × 0.25)
x = (20 × 0.25) / 8
x = 5 / 8
x = 0.625
Force = 0.625N
The sound is basically just frequency. Because the sound becomes higher in pitch.
