B. A polystyrene ice box has a total area of 0.92 m2 and walls with an average thickness of 2.5cm. The box contains ice, water and canned
beverages at 0 degree Celsius. The inside of the box kept cooled by
melting ice. How much ice melt in one day if the ice box is kept in the car
boot at 35 degrees Celsius?
(K polystyrene = 0.001 W/mc).
Can you please answer the question? Thanks

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter

Glass has a hardness that is in the middle of the hardness scale. what is the hardness of glass?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
