Ok when we inhale we are letting oxygen inside of us, that oxygen that we inhale helps our blood move around our bodies. When we breath out taking out all the old air thats called carbon dioxide and it is very dangerous because it can make us stop breathing if we dont find new oxygen fast. Please if you need more info just private message me.

(2<br>Find the mass of an object if a force of 40N gives it acceleration of 2m^s

Rom4ik [11]

Answer:

m = 20 kg

Explanation:

Given that,

Force, F = 40 N

Acceleration of the object, a = 2 m/s²

We need to find the mass of the object. Let the mass be m.

We know that,

Net force, F = ma

So,

$m=\dfrac{F}{a}\\\\m=\dfrac{40}{2}\\\\m=20\ kg$

So, the mass of an object is equal to 20 kg.
