A Styrofoam box has a surface area of 0.20 m^2 and a wall thickness of 2.0 cm. The temperature of the inner surface is 0°C, and the outside temperature is 25°C. If it takes 2.0 hr for 5.0 kg of Si wafers to increase temperature from the initial 0°C to 10°C, determine the thermal conductivity of the Styrofoam. The molar heat capacity of bulk Si is 19.8 J/mol. K, molar mass of Si is 28.0 g/mol. Required:
Determine the thermal conductivity of the Styrofaom.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

i'm on my way to history not a mistory.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
