Answer:
Lastly, the heat transfer rate depends on the material properties described by the coefficient of thermal conductivity. All four factors are included in a simple equation that was deduced from and is confirmed by experiments. The rate of conductive heat transfer through a slab of material, such as the one in Figure 3, is given by

where
Q
t
is the rate of heat transfer in watts or kilocalories per second, k is the thermal conductivity of the material, A and d are its surface area and thickness, as shown in Figure 3, and (T2 − T1) is the temperature difference across the slab. Table 1 gives representative values of thermal conductivity.
Explanation:
125 because f=ma so you would use 100=mx0.75
It describes physics, chemistry and engineering. i dont know if you meant that but oh well.
Answer:
When you rub a balloon on your head, electrons move from the atoms and molecules in your hair onto the balloon. Electrons have a negative charge, so the balloon becomes negatively charged, and your hair is left with a positive charge.
