Answer from: SchoolSucks234

The acceleration of the object is 4 m/s²

Explanation:

Newton's Second Law, also called the Fundamental Law of Dynamics, indicates that: "The change of motion is directly proportional to the printed driving force and occurs along a straight line along which that force is printed." This means that the acceleration of a moving object depends on the amount of force applied at a given time, in order to modify its trajectory or speed.

In summary, this law establishes that the net force applied to a body is proportional to the acceleration that body acquires. The constant of proportionality is the mass of the body, and this law can be expressed as:

F = m * a

where:

F=Force m=mass a=acceleration

In this case it is necessary to know the acceleration, then:

$a=\frac{F}{m}$

An object with a mass of 20 kg has a net force of 80 N acting on it. So,

F= 80 Nm= 20 kg

Replacing:

$a=\frac{80 N}{20 kg}$

Knowing that N is a unit of measure that is obtained as kg * m/s²:

a= 4 m/s²

The acceleration of the object is 4 m/s²

2 ) $4 ms^{-2}$

Explanation:

By Applying Newton's second law of motion

Force = mass * acceleration

$acceleration=\frac{force}{mass} \\=\frac{80}{20} \\= 4 ms^{-2}$

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

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
