Ascale model of 1: 25 of a ship has a submerged area of 6 m2 a length of 5 m in which a drag force (ed) of 25 n is measured when an experiment is carried out in water with a speed of 1.2 m/s. calculate the total drag force in the prototype. remember that the total drag force is due to the friction forces plus the pressure forces. the friction force can be estimated by the following relationship where coefficient cf= 0.0735 /. assume that the dynamic viscosity is 0.001 pa-s and density of 1030 kg / both for the model and the prototype.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.

answer:

in baseband transmission the whole bandwidth of the cable is utilized by a single signal. eg.Ethernet is using Basebands for LAN.

In the broadband transmission, multiple signals are sent on multiple frequencies simultaneously using a single channel. eg.Digital Subscriber Line (DSL)
