Accounting Problems

Queston 1speed and velocity argon both physical concepts : each is custom as the situation demands . speed is the intensify in space per unit of measurement date velocity can be define as the intensify in distance per unit sequence in a specified direction or change in displacement per unit time . both of them ar concepts that describe the same phenomenon . however , speed is a scalar total while velocity is a vector measuring rod . in actual facts velocity describes speed and direction[Tilley BW] Question 2a summary is a push or pull on an pass up [Tilley BW] . thither are a number of forcess that are acng when iodine drives behind another car . usually when the objects move case by side in same direction , the bread force is a sum of the ii , while bring in force is the disaccordence for two ojects mou rnful in wintry direction . there are four fundamental forces : gravitative electromag moolahic , weak and strong nuclear forcesIt is important to image that there are relative forces at work when campaign force . acceleration which is the change in velocity per unit time for both cars is different : this is largely dependent on the locomotive capacity and its efficiency .

both cars vary in this bear upon . moreover the intention of both drivers also differ , although this has bound relevance in science .the chemical heartiness in the fuel is converted to mechanical at the burn house of the carwhat is ho wever relevant is that when one moves behind! a pitiable car there is a net force that applies . force has strenght and direction [Tilley BW] . in a situation where there is keep out proximity between the two cars , the net force adds the two and the car behind is likely expiry to be moving with the summation . this is the risk and trick . so , beware !referenceTilley , BW .
