Answer:
<em>2</em><em>, The spring would compress twice the length of </em><em>. </em>
Explanation:
The Spring force is an application of Hooke's law, and using the law of conservation of energy in a spring system, we can find the relationship between the compression length and velocity.
<h3>Step by Step Calculations</h3>
For a spring system, the conservation of energy can be applied using the formula below;
........................................1
Where k is the spring constant
is the distance
m is the mass and
v is the velocity
We have to make the distance the subject formula to know how it affects the velocity;
.....................................2
from the equation, it shows that the distance () is directly proportional to the velocity (v). This implies that when the distance increases the velocity also increases.
x ∝ v
Therefore when the initial speed is doubled to 2 v it will amount a double increase in the distance which is 2
The light can definitely change the mystery material. This can occur through a change in temperature or color (option C).
A material is affected by light mainly if the material absorbs the light. Based on the chart, we know this mystery material can absorb two types of light:
Moreover, this phenomenon can lead to two main changes:
- Change in temperature: Light affects materials by increasing their temperature of these. A common example is the way the temperature of an object increases if it is exposed to sunlight.
- Change in color: Some materials react to light by changing their color.
Based on this, the material can change its color or temperature.
Note: This question is incomplete; here is the missing part:
A. Yes, but the mystery material can change in only one way, such as by getting warm, because all the light that a material absorbs will affect that material in the same way.
B. No. The mystery material can’t change because the light is not a physical thing. Light cannot change physical things like the mystery material.
C. Yes and the mystery material can change in one or two different ways, such as by getting warm and/or changing color, because different types of light can cause different changes to a material when they are absorbed.
D. There is no way to know whether the mystery material will change or not.
