Answer:
(a) more than
Explanation:
Conduction:
Transfer of heat due to direct contact between two mediums at different temperatures, without having any of the bodies traveling. Therefore, conduction heat transfer occurs by the transfer of momentum (molecular) from always the same group of molecules in one medium to another group of molecules in another medium.
Example: Heat transfer INSIDE a solid.
Convention:
Transfer of heat or mass due to at least one traveling medium, where the transfer of momentum is not bounded anymore to the same groups of molecules. Molecules moving to transfer their momentum and keep flowing to the next group, also allowing other molecules behind to do the same. Example: heat transfer by the wind.
Hence, the Mass transfer rate in convection is <u>more than</u> mass transfer in conduction
Answer:
Carbon
Explanation:
Carbon has the atomic number 6 meaning it has 6 protons and 6 electrons to it will have 6 electrons occupying spherical shaped orbitals

Non metals.
metalloids are substances that have both properties of metallic and non-metallic
The permanent magnet in the loudspeaker is fixed close to a mobile electromagnet coil. The electromagnet is attached to a flexible material called cone (). Passing an electric current in the electromagnet causes it to vibrate due to the interaction with the permanent magnet.Uh hope this helped.
