Just divide the two numbers with each other.
I mean 13/1.4=9.2857...
Answer:

Explanation:
According to the free-body diagram of the system, we have:

So, we can solve for T from (1):

Replacing (3) in (2):

The electric force (
) is given by the Coulomb's law. Recall that the charge q is the same in both spheres:

According to pythagoras theorem, the distance of separation (r) of the spheres are given by:

Finally, we replace (5) in (4) and solving for q:

Answer:
GPE = 388.08 Joules.
Explanation:
Given the following data;
Mass = 0.550kg
Speed = 335 m/s
Height = 72 meters
We know that acceleration due to gravity, g is equal to 9.8 m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;

Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the formula, we have;

GPE = 388.08 Joules.
If we are being specific, the inner core has the highest density, but if not then the core in general
