Respuesta :

the answer is N because i have done this be for because im in k12 and i got 100% right

Answer:

The normal force acting on it is 127.4 N.

Explanation:

Given that,

Mass of a dog = 13 kg

Normal force :

The supported force exerted upon a dog that is in contact with the surface it is called normal force.

Normal force is defined as:

[tex]F = -mg[/tex]

Where,

F = normal force

m = mass of dog

g = acceleration due to gravity

Put the value of mass into the formula

[tex]F = -13\times9.8[/tex]

[tex]F = -127.4\ N[/tex]

Negative sign shows the upward direction of the normal force.

Hence, The normal force acting on it is 127.4 N.
