A 35 N block rests on a horizontal surface. The coefficients of static and kinetic friction between the surface and the block are 0.6 and 0.3, respectively. A horizontal string is attached to the block and a constant tension is maintained in the string. What is the force of friction acting on the block if the tension is 16 N? Answer in units of N. What is the force of friction acting on the block if the tension is 38 N? Answer in units of N.

(a) Frictional Force = 16 N

(b) Frictional Force = 10.5 N

Explanation:

(a) FOR TENSION OF 16 N:

First we find the static friction force (Fst):

Fst = (μs)(W)

Fst = (0.6)(35 N)

Fst = 21 N

Since, Tension < Fst

Frictional Force = Tension

Frictional Force = 16 N

(b) FOR TENSION OF 38 N:

Since, Tension > Fst

Frictional Force = Kinetic Friction = (μk)(W) = (0.3)(35 N) =  

Frictional Force = 10.5 N

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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
