Answer:
The weight of the objects has a name and is "Specific weight", this is measured in several measurements but the best known is the kg.
If we relate the density of the object with the weight we will obtain a deduction of the shape of the object.
Explanation:
The object can be more or less heavy according to its density and its chemical composition.The weight is nothing more than the attraction of that object with the interior of the earth, that is why in order to know well how heavy it is, it is necessary relate the density of the object, the material that composes it, the speed of gravity (10m / s2).
This refers to the fact that a kilo of feather is not the same as a kilo of lead, each object obtains its shape according to the more weight it has and the more attraction it can make to the center of the earth.
Answer:
5.10¹¹ N/C
Explanation:
As we have a proton and a neutron, we can consider that they both have the same charge, this is:
e- = e+ = |1,6x10⁻¹⁹ C| , this number is in absolute value
Then, the formula needed to calculate the magnitude of the electric field from a charged particle is:
E= kqQ/r²
Where:
K= Coulomb constant
Q= charge
r = distance between two charges
Then:
E= 8.99x10⁹N/C²*(1.6x10⁻¹⁹C)/(5.3x10⁻¹¹m)²
E=5.12x1011 N/C
It is important that this value is a magnitude, it does not have any sign (positive or negative), for the magnetic field
6.16 I did the math so I know it is correct
