<span>Surface friction is typically the main factor regarding slippage between two objects. If the objects are coarse and not smooth, they will most likely grip and not slip easily. If the objects are smooth, they are more likely to slip. Another factor is whether or not lubricant is involved. Even finely tuned cogs and gears can slip if lubricated in excess.</span>
Explanation:
From birth, babies have only the gestures, some sounds and crying to communicate and transmit their needs and emotions to the people around them.
The pre-linguistic or non-verbal stage is called that precisely because there are no words, what there are are sounds, approximations, twitter, babbles, cries and smiles, which constitute the first stage where children already begin to communicate, and it lasts longer or less until twelve months.
The gestures and sounds reveal the baby's mood, as well as different needs: eating, having physical contact, changing diapers, sleeping, drinking, etc. Babies always transmit and communicate.
Answer:
Set target for a statistically significant improvement compared to the current value.
Explanation:
For programs that are innovative, address rare health problems, or are highly tailored to the location a target of value of a statistically significant improvement compared to the current value is set. It is appropriate when there is credible data source and policy makers need to be convinced on an investment that is worthwhile. Also, change can happen anytime and planners must be able to set an argument that greater change will most likely occur by chance alone. The Z-test is used to determine the amount of change that is statistically significant. Very often, the significance level is set at p= 0.05 which implies that the probability of reaching the target by chance alone is 5% or less than 5 in 100 which translates to a Z-score of 1.96 which is used to estimate the target value.
The correct answer to this open question is the following.
Although the question has no options, we can say the following.
During a speech, the speaker notices that the audience seems to be a bit hostile to what she is saying, so she begins to change her message to try and woo them over. She is adapting to the audience's reactions and expectations.
If the speaker has his speech already prepared, it has to focus on the reaction of the audience in order to know the kind of effect of its speech. If the audience is not responding, the speaker has to adapt the message to the audience's interest, beliefs, attitudes, expectations, previous experience, or level of understanding. That is why it is important that the speaker previously research the kind of audience he/she is about to meet.
