Amining company plans to improve the infrastructure in a location to start mining activities. the company calculated the costs and earnings listed below to find out if mining would be economically feasible in the location. a: cost of land for mining b: cost of equipment c: cost of labor d: miscellaneous costs related to mining e: cost of reclamation f: earnings from selling the resulting mineral how can the mining company best decide whether mining activities in the location would be economically feasible? select one: a. by confirming that f is greater than a + b + c + d + e b. by confirming that d is greater than a + b + c + e + f c. by confirming that b is lesser than a + c + d + e + f d. by confirming that c is lesser than a + b + d + e + f

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i.e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
