2399 A concrete wall in a cold storage room measures 3.2 m high and 4.7 m wide. The inside wall is to be covered by a layer of wood in order to reduce the rate of heat flow through the wall. The cold room is to be maintained at 2°C and the outside is 16°C. The thermal resistance of concrete is 0.26 m2-°C/W. Part Description Answer Save Status A. Determine the required thermal resistance of the wood (units of m2-°C/W) so that the heat flow through the wall is 476 Watt.

I'm kinda lost ! 1. when marilyn takes her pet dog for a walk, the dog walks at a veryconsistent pace of 0.55 m/s. draw a position-time graph to representmarilyn's dog walking the 19.8 m distance from the front of her house tothe nearest fire hydrant.2. both car a and car bleave school when a stopwatch reads zero. car atravels at a constant 75 km/h, and car b travels at a constant 85 km/h.a) draw a position-time graph showing the motion of both cars. howfar are the two cars from school when the stopwatch reads 2 hrs? calculate the distances and show them on your graph.b) both cars passed a gas station 120 km from the school. when dideach car pass the gas station? calculate the times and show themon your graph.3. the figure below shows the position-time graph showing a shopper'smovement up and down the aisle at a store.a) write a story describing the shopper's movements at the store.b) when does the shopper have a position of 6 m? c) how much time passes between when the shopper enters the aisleand when he gets to a position of 12 m? what is the shopper's averagevelocity between 37 s and 46 s?

Two models of the same compound are shown. in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three-dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not

The steel pipe ab has a 102-mm outer diameter and a 6-mm wall thickness. knowing that arm cd is rigidly attached to the pipe, determine the principal stresses and the maximum shearing stress magnitude at point k. (round the final answers to one decimal place.) given: f = 10 kn
