Answer:
Spring constant, k = 1.16 N/m
Explanation:
It is given that,
Mass of the air track, m = 0.2 kg
Time, t = 2.6 s
Let T is the time period of the spring. The expression for the time and spring constant is given by :
k = 1.16 N/m
So, the spring’s force constant is 1.16 N/m. Hence, this is the required solution.

Answer:
Conduction is usually faster in certain solids and liquids than in gases. Materials that are good conductors of thermal energy are called thermal conductors. Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily.
Heat transfer by convection happens through the air, and there are millions of minuscule air spaces between the fibers. Heat transfer by radiation is also slow since one fiber must radiate its heat to another.
When we give heat then kinetic energy is increase and this heat is transferred from hot metal to cold metal through this free electrons. As in insulator the free electrons are negligible so that the heat is not transferred from hot junction to cold junction due to absence of this free electrons.
