The equation that shows the relationship between X₁ and X₂ in the springs is X₁ = 4X₂.
<h3>How to compute the equation?</h3>
From the complete question, for case I, the two springs stretch up to the distance of X₁. Therefore, f = mg = kx₁.
For case 2, f = mg = kx₂.
Therefore, we'll equate the equations. This will be:
Kx₁ = Kx₂
(K/2)x₁ = (2k)x₂
K(x₁/2) = k(2x₂)
X₁/2 = 2x₂
X1 = 2 × 2x₂
X₁ = 4X₂.
In conclusion, X₁ = 4X₂.

Answer:
0.000136kg/m3
Explanation:
13.6 / 1000 = 0.0136kg/cm3
0.0136 / 100 = 0.000136kg/m3
The same thing that holds everything else 'down' --- gravity.
Answer
The potential energy is less
Explanation:
From the question we are told that
The source of the emf is by wires to a resistor.
Now the potential energy of electron before leaving the source emf will be greater than the potential energy of an electron after leaving the source of emf because the resistor connected to the source emf will reduced the potential energy as it will convert some of the energy to heat
Answer:
Explanation:
Given
Distance to the planet = 35 light years. So, the entire distance is: 2 * 35 = 70.
i.e time of travel of the ship.
For the observer on earth, the time is:
The required speed so that it does not take more than 70 years is then calculated using:
Substitute
So, we have:
Make v the subject of formula.
Square both sides
Cross Multiply
Divide both sides by
Divide through by
Make the subject
Inverse both sides
Take square root of both sides
Substitute values for and
