I believe that you would weigh around 68 or 69 N, or 7 kilograms.
Answer: the minimal force that you need to apply to move the bureau is F = 198.45N
Explanation:
If you want to move an object, you need to apply a force that is bigger than the force of the statical friction.
The force of statical friction can be written as.
Ff = k*N
where k is the coefficient of static friction, in this case, k = 0.45, and N is the normal force between the object and the surface.
In this case, the normal force is the weight of the bedroom bureau, this is:
N = m*g = 45kg*9.8m/s^2 = 441N
Then the force is:
Fr = 0.45*441N = 198.45N
This means that the minimal force that you need to apply to move the bureau is F = 198.45N
and after this point, the force of friction will work wit the kinetic coefficient of friction, that usually is smaller than the statical one.
Your answer is:
<em>The origin, structure, and future of the universe</em>
You can just search up the definition of Cosmology and receive your answer. Hopefully this helps at least a little :3
Either 25% or 75%. does it to how much is wasted or the difference in the input and waste?
