Consider a 1.5-m-high and 2.4-m-wide glass window. whose thickness is 6 mm and thermal conductivity is k = 0.78 w/m·k. determine the steady rate of heat transfer through this glass window and the temperature of its inner surface for a day during which the room is maintained at 24°c while the temperature of the outdoors is −5°c. take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1, = 10 w/m2·k and h2 = 25 w/m2·k, and disregard any heat transfer by radiation.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.

The vapour pressure of benzene is 53.3 kpa at 60.6 °c, but it fell to 51.5 kpa when 19.0 g of a non-volatile organic compound was dissolved in 500 g of benzene. calculate the molar mass of the compound.

Aracecar driver has to hold on tightly when going around a banked curve. approximately what is the centripetal force on a 2220.0 kg car going around a circle with a diameter of 190.0 meters at 25.0 m/s?
