Based upon the calculation of the force, Fapplied, calculated in the previous step, how much power must be put into the system in order to maintain the constant speed of the rail?

Power that must be put into the system for an applied force, F, to keep the rail in motion at constant speed, v,

= (Fapplied) × (constant speed of the rail)

P = Fv

Explanation:

The question is incomplete; but the solution to this is straight forward.

The power required to be put into the system for an applied force, F, to keep a rail/body/object in motion at a constant speed of v, is given as

Power = (Fapplied) × (The constant speed)

P = Fv

Hope this Helps!!

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

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
