Compute the value of the horizontal force P necessary to a. just start the block up the incline b. just prevent motion down the incline If \( \mathrm{P}=1780 \mathrm{~N} \), what is the amount and direction of the friction force?
Which of the following observations was made famous by Adam Smith? Group of answer choices People buy more when prices are low than when prices are high. Households and firms interacting in markets are guided by an "invisible hand" that leads them to desirable market outcomes. No matter how much people earn, they tend to spend more than they earn. There is no such thing as a free lunch.

Question Completion Status: QUESTION 3 A trash compactor compresses garbage by pressing air out and forcing the same mass of material into a smaller volume. Ignoring the mass of the escaping air, if a trash compactor can reduce the volume of a bag of trash to 0.3 times its original value, by what factor is the density changed? QUESTION 4 Suppose you have a coffee mug with a circular cross section and vertical sides (uniform radius). What is its inside radius (in cm) if it holds 295 g of coffee when filled to a depth of 7.5 cm? Assume coffee has the same density as water (1.00 g/cm³). QUESTION 5 If you've had the misfortune of having the pipes in your home freeze, you are well aware that ice is less dense than water (i.e., ice takes up more space than an identical mass of water). Given water's density of 1.000 kg/m³ and ice's density of 900 kg/m³, what is the maximum mass (in kg) of water that you can put into a 0.00069 m³ container in the freezer without having it overflow as the water freezes?
