Aparticle that has a mass of 5.0 kg is acted on by a force of 4.5 n. the acceleration of the particle is: a 0.9 m/s^2 b 1.1 m/s^2 c. 2.9 m/s^2 d. 22.5 m/s^2

a)

Explanation:

As per Newton's 2nd law we know that net force on an object of mass "m" is given by the formula

so net force is the product of mass and acceleration

here we know that

mass = 5 kg

net force on the particle is 4.5 N

so from above equation we have

so the acceleration is given as

correct it is c.) b b

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
