The inclined plane is studied by mechanics and, to calculate it, we use Newton's Second Law.
Is a block of mass “m” supported by an inclined ramp at an angle? with respect to the horizontal plane. Despise the friction.
Forces acting on the body are: image 1
P: Force weight = P = m.g
Where: g = 9,8 m / s2
m = body mass given in kg.
FN: Normal reaction force to the plane.
When we neglect friction we notice that the body moves downwards. image 2
Answer:
Negative reinforcement
Explanation:
Negative reinforcement can be defined as the acts or behaviour carried out by person in order to encourage someone to do what he /she said.
Negative reinforcement are often use to encourage or motivate someone and as well change the person behaviour. It also strengthened a person behaviour by removing negative result.
This example "Elton's mother has been nagging that he should practice at the piano for the upcoming competition. Elton eventually complies to stop her nagging" simply illustrates NEGATIVE REINFORCEMENT because Elton's mother was nagging in order to encourage Elton's to practice the piano for the upcoming competition and as well change is behaviour in which Elton finally complies to do what she said due to her nagging.
Anthropological survey of such rituals gives a peek into societies with no surviving written history.
Explanation:
Modern native cultures are the ones that have survived a rigorous process of termination and getting westernized.
To safeguard them, the anthropologists need to document their rituals and decode their dances for possible symbols and way of life as it developed in the place when there was no issue of the extinction
It is only through the dances and rituals of these people can we get a peek into what their core values are and how their history has been in the absence of any written records.
Answer:
2) "Multiple drugs are necessary because the bacteria are likely to develop resistance to just one drug."
Explanation:
Tuberculosis is caused by multiple bacteria, and these bacteria can easily develop resistance if only one antibiotic is used. Current medical research recommends the usage of several antibotics in the treatment of Tuberculosis for these same reasons.
