Typically occurs when we associate things to other things that look alike. We see that in many experiments, specifically “Little Albert” who was conditioned to be afraid of rats but later was afraid of anything that resembled that of a rat.
Hope this helps!

Answer
Any force greater 490N
Explanation
The force required just to make an object slide over a rough horizontal surface is any force greater that the static friction which given by;
Given;
Hence;
F = 0.5 x 100 x 9.8
F = 490N.
We will only need the coefficient of kinetic friction if we were asked to find the force required to keep the object moving uniformly. Usually, the force needed to keep an object moving uniformly over a rough surface is lesser that which is needed to start its motion.
In this problem, we were only asked to find the minimum force required to make the object move which we have done.
Explanation:
A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity.
The change in the internal energy of the system will increase.
The given parameters;
- <em>work on the system, w = 150 J</em>
- <em>heat added to the system, Q = 270 J</em>
<em />
The change in the internal energy of the system is calculated by applying first law of thermodynamics as follows;
ΔU = Q + w
where;
- <em>ΔU is the change in the internal energy</em>
ΔU = 150 J + 270 J
ΔU = 420 J
Thus, the change in the internal energy of the system increases.
