This is called the nucleus
Answer:
C. greater than D, but less than 2D
Explanation:
The amount of potential energy in the system is a function of the compression of the spring. That is the same for both masses.
The potential energy is transferred to kinetic energy when the spring is released. The kinetic energy is jointly proportional to the mass and the square of the velocity. That is, the velocity is inversely proportional to the square root of the mass, for the same kinetic energy.
The horizontal distance traveled will be proportional to the launch velocity. So a halving of the mass will increase the velocity by a factor of ...
v2 = v1·√(1/(1/2)) = v1·√2
This means the second mass will land at a distance of about D√2, a value ...
greater than D but less than 2D.
Answer:false
Explanation:
Given
Two equal positive charge are held in place at a fixed distance
Suppose q is charge and 2d is the distance between them
Suppose is the third charge which is placed d distance apart from q
Now the force by charge q will make the charge to move right while other charge cause the charge to move left.
Overall forces by charge q will cancel out each other
Now electrical Potential Energy
It is clear that
Therefore above statement is false.
Qs 1: Yes, there is a force, and distance, and they point in the same direction.
Qs 2: 420,000 J
