<span>Operant conditioning by Burrhus Frederick
Skinner, showed that people learn to behave in certain ways because of
reinforcement. This a product of a psychology school of thought, behaviorism,
which comes in the notion that whatever a person behave is what matters instead
of his mind, pioneered by John B. Watson. If a person wants to retain the
behavior, then he will do positive reinforcements example, positive stroking.
If the behavior is undesired and needs to be exterminated, then a punishment will
be instilled.</span>
Explanation:
Momentum before = momentum after
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
(50.0 kg) (0 m/s) + (12.0 kg) (0 m/s) = (50.0 kg) (2.0 m/s) + (12.0 kg) v
v = -8.33 m/s
Answer: Coral reef structures also buffer shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal communities from normal wave action and violent storms.
Answer:
Part a)
Part b)
Explanation:
Part a)
as the mass of the suspension system is given as
also we have
so now for force balance we have
Part b)
Now we know that amplitude decreases by 63% in each cycle
so after one cycle the amplitude will become 37% of initial amplitude
so it is given as
also we know
here t = time period of one oscillation
so it is
now damping constant is
