Answer:
The electrical force between the given charges remains the same.
Explanation:
The expression for the electrical force is as follows as;
Here, k is the constant, are the charges, F is the electrical force and R is the distance between the charges.
It is given in the problem that the magnitudes of the charges and the magnitudes of the separation between the charges are doubled.
Then, the expression of the electrical force becomes as;
Therefore, the electrical force between the given charges remains the same.
To develop this problem it is necessary to apply the concepts related to Broglie hypothesis.
The hypothesis defines that
Where,
P = momentum
h = Planck's constant
The momentum is also defined as,
P = mv
Where,
m = mass
v = Velocity
PART A) Replacing at the first equation
Our values are given as,
Re-arrange to find v, we have:
PART B) From the kinematic equations of movement description we know that velocity is defined as displacement over a period of time, that is
Re-arrange to find t,
the age of the universe.
1.39m/s
Explanation:
Given parameters:
Mass of car M₁ = 1000kg
Velocity V₁ = 2.5m/s
Mass of second car M₂ = 1800kg
Unknown:
Velocity of second car V₂ = ?
Solution:
For the other body to come to rest, the momentum of the colliding cars must be equal and in the opposite direction:
Momentum of car 1 - momentum of car 2 = 0
Momentum of car 1 = Momentum of car 2
M₁V₁ = M₂V₂
The unknown is V₂
1000x2.5 = 1800V₂
V₂ = = 1.39m/s

Your answer would be B because although the Moon is gone, the sun still has a gravitational pull towards the oceans waves
