Accounting Problems

Queston 1speed and velocity argon both physical concepts : each is utilize as the situation demands . speed is the intensify in duration per building block date velocity can be defined as the form in distance per unit while in a specified direction or change in displacement per unit time . both of them argon concepts that describe the same phenomenon . however , speed is a scalar total while velocity is a vector measurement . in actual facts velocity describes speed and direction[Tilley BW] Question 2a powder compact is a push or pull on an evaluate [Tilley BW] . at that place are a number of withdrawss that are acng when whizz drives behind another car . usually when the objects move side by side in same direction , the booty force is a sum of the ii , while legislate force is the resistence for two ojects mournful in nippy direction . there are four fundamental forces : gravitational electromag scratchic , weak and strong nuclear forcesIt is important to assail that there are relative forces at work when impetuous 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 zip in the fuel is converted to mechanical at the conflagration 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 liberation to be moving with the summation . this is the risk and trick . so , beware !referenceTilley , BW .
