What is a chain reaction simple definition?
1a : a series of events so related to each other that each one initiates the next. b : a number of events triggered by the same initial event. 2 : a self-sustaining chemical or nuclear reaction yielding energy or products that cause further reactions of the same kind.
What starts a chain reaction?
Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. For example, 21/2 neutrons on the average are released by the fission of each uranium-235 nucleus that absorbs a low-energy neutron.
What causes the ripple effect?
When you throw a rock into a river, it pushes water out of the way, making a ripple that moves away from where it landed. The water usually rushes back too enthusiastically, causing a splash – and the bigger the rock, the bigger the splash.
Why is the emotional contagion effect influential?
Emotional contagion is important to personal relationships because it fosters emotional synchrony between individuals. When people unconsciously mirror their companions’ expressions of emotion, they come to feel reflections of those companions’ emotions.
Is ripple effect positive or negative?
When the object hits the water, ripples expand incrementally, flowing outwardly. The ripple effect is a situation in life in which when one thing occurs, it has a direct effect on other situations and the chain goes on and on and on. Most often, the effect is spoken about positively.
What is the ripple effect in life?
If we set in motion a certain decision or action it ripples through our life – with positive and negative impact. Check out this example: If I come home from a stressful day and snap at my wife and kids. The negative ripple effect is released and it changes the attitude of everyone in the home.
What is a water ripple?
Ripples are the instant effect of wind on water and they die down as quickly as they form, as the surface tension of the water dampens their efforts. If a wind blows steadily across a large enough patch of water for a few hours then the ripples become waves and these will not be dampened so easily.
What causes a ripple in the water?
Ripples in water are more formally known as capillary waves, and are caused by the subtle interaction of wind and water, or the physical interaction of the water with another object. Even if there isn’t a whisper of wind against your face, you will likely still see faint lines and irregularities in the water.
Why does water ripple when you touch it?
You might already know that everything you can touch is made up of lots of tiny molecules, which are themselves made up of even smaller parts called atoms. Water is also made of molecules. But during a ripple, the water molecules don’t move away from the rock, as you might expect. They actually move up and down.
