A force act on a bicycle for 2.4 sec, and changes its momentum from 20 kg m/s in the x positive direction to 40 Kg m/s in the Positive x direction, what is the magnitude of the force? A. -10 N
B. 137.5 N
C. 8.33 N
D. -137.5 N

Increased momentum =40-20=20

F=P/T=20/2.4=8.33N

Explanation:

F=(force)

P=(momentum)

T=(time)

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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
