Answer:

Explanation:
Since the package remains in contact with the car's seat, the package's speed is equal to the car's speed. At the top on the mountain the package's centripetal force must be equal to its weight:

The centripetal force is defined as:

Here v is the linear speed of the object and r is the radius of curvature. We need to convert the linear speed to
:

Now, we calculate r:

Answer:
When Jill is pushing a box across a floor, it represents the upward motion and it is natural force is applied.
So it is represented as FN and normal force takes place in considering the force perpendicular to the floor.
It seems to support that forced applied on an object when the object is in contact with other.
Explanation:
Answer:
Datos:
q1 = -50 μC = 
q2 = +30 μC = 
F = 10 N
a) x si la <em>F = 10N</em>
Aplicando la Ley de Coulomb:
x =
=
= 1,162m
b) x si la <em>F = 20 N</em>
x=<em> </em>
<em> </em>= 0,822m
c)x si la <em>F = 50 N</em>
x =
= 0,520m
Cations are positively charged ions. And for positive charged ions, it means the positive charges, protons, are more than the negative charges, the electrons.
Therefore Cations have fewer electrons than protons.
So the answer is: c. electrons; protons.
