Answer:
C. A Spring Scale
Explanation:
Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!
We know, Kinetic energy (movement of the particle) is directly proportional to the temperature of the object. When you decrease the temperature, it's movement will also decrease and object particles move slower.
In short, Your Answer would be Option B
Hope this helps!
