Asolution is prepared by dissolving 98.6 g of nacl in enough water to form 875 ml of solution. calculate the mass % of the solution if the density of the solution is 1.06 g/ml.

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
