Adog wishes to swim across a slow-moving stream. the dog can swim at 2.0m/s in calm water. the velocity of the current is 3.0m/s. the distance directly across the stream is 50m.
a) how long does it take dog described above to swim 50m in a bost of water that has no current?
b) how far downstream will current have carried the dog in the time it takes the dog to get across the stream?
c) calculate dog’s resultant velocity relative to bank from where the dog started.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
