What is the mass of an object if force of -136 n can make it accelerate at -9.6 m/s^2

The answer for the following problem is mentioned below.

Explanation:

Force:

The push or pull on an object with mass that cause change in the velocity

It is a vector quantity.

The formula to calculate the force is:

F = m × a

Given:

Force (F) = -136 N

acceleration (a) = -9.6 m/s^2

To calculate:

mass of the object (m)

We know that,

F = m × a

where,

F represents the force of the object

m represents mass of an object

a is acceleration of an object

From the equation;

-136 = m × -9.6

m =

m = 14.16 grams

Therefore the mass of an object is 14.16 grams.

thats a little if u want the answer just look it up on google thats what i do haha : )

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
