Consider a home freezer compartment with dimensions of height 30 inches, width 60 inches, and depth 25 inches. Assume heat loss is from the five sides exposed to outside air (i. e. do not consider any heat loss through the bottom surface which the freezer sits on). For a Styrofoam insulation of thermal conductivity 0.025 W/m-K. Required:
What should be the minimum thickness of this insulation so that the total heat loss from the freezer compartment is less than 120 W?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
