Answer:
If the distance between two charged particles is doubled, the force between them changes by a factor of
Explanation:
Answer:
Explanation:
According to the law of conservation of energy, the energy of the absorbed photon must be equal to the binding energy of the electron plus the energy of the released electron:
1 eV is equal to 
, so:
Solving for 
and replacing the given values:
1. What is the weight of this objects?
Weight is simply the product of mass and gravitational
acceleration. Therefore the weight is:
w = 20 kg * 9.81 m/s^2
w = 196.2 kg m/s^2 = 196.2 N
2. After 5 seconds, how has the object fallen and what is its
speed at this instant?
We can use the formula:
<span>y = v0 t + 0.5 g
t^2</span>
v = v0 + g t
where v0 = 0 since the object starts from rest, y is the
distance it fell, t is time
y = 0 + 0.5 * 9.81 * 5^2 = 122.625 m
<span>v = 0 + 9.81 * 5 = 49.05 m/s</span>
