Answer: Where the charged object is brought near but never contacted to the object being charged, conduction charging involves making the physical connection of the charged object to the neutral object. Because charging by conduction involves contact, it is often called charging by contact.
Real life example: A positively charged aluminum plate comes into contact with a neutral metal sphere
Explanation:
Answer:
Explanation:
If
- , are temperatures of gasses and liquid in Kelvins,
- and are thicknesses of gas layer and steel slab in meters,
- , are convection coefficients gas and liquid in ,
- is the contact resistance in ,
- and are thermal conductivities of gas and steel in ,
then: part(a):
using known values:
part(b): Using the rate equation :
the surface temperature
and
Similarly
The temperature distribution is shown in the attached image
Base from the pressure-flow hypothesis, the sieve tube in the phloem should be living cells because sugars are transported across the membranes by the active transport which needs ATP that is produced during respiration. Hope this helps.
Answer:
wave front
Explanation:
wave front is an imaginary line of a wave that joins all adjacent points that are in phase,
so that's the definition, and you apply it to the question
it obviously can't be the rest
