An object is hanging by a string from the ceiling of an elevator. the elevator is slowing down while moving upward.

what is the magnitude of the tension in the string?

The magnitude of the tension is less than the object's weight

Explanation:

As per the question:

From Fig. 1

The forces and the acceleration are shown in the figure

Since, the elevator slows down in its upward motion, this means that the final velocity is less than the initial velocity and the elevator decelerates.

Therefore, we take the acceleration as negative, '- a'.

Thus

Balancing the forces:

T - mg = m(- a)

T = mg - ma = m(g - a)

Thus it clearly shows T < mg

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
