2. Practice presenting in front of friend or family
3. Practice presenting in front of a mirror
4. time the length of your presentation
Answer;
3. Practice presenting in front of a mirror
Explanation;
Like scientific papers, oral presentations at a conference or internal seminar are for sharing your research work with other scientists. They, too, must convince the audience that the research presented is important, valid, and relevant to them.
Planning a presentation involves a comprehensive assessment of the speaking situation. It is important to know the purpose of the presentation, know the audience and also where the presentation will take place, among other important aspects.
Answer:
The correct answer is option 2. Practice presenting in front of friend or family
Explanation:
Generally while making an oral presentation three things are very vital-
a) Cover all the vital points of the research work presented through oral presentation thus writing all the points on a piece of paper is must.
b) One must use appropriate body gesture while giving the presentation , thus practicing in front of mirror is also a required exercise
c) The presenter must be able to deliver his/her presentation in the stipulated time period thus timing the presentation is also important.
Since mirror practice is sufficient to work on body language, eye contact with the audience and gesture, thus there is no need to practice in-front of friend or family.
The dimension of b and c is and
Since the x axis may be determined from the expression that shown below.
Here, x will be in meters when t is in seconds
Now
Here the dimension of the right side should be equivalent to the left side.
According to the left side the dimension should be same like length or meter so same goes for the right side
So,
Now for another one it is

As per given equation we have
now as per the dimensional analysis we can say that dimension of right side of equation must be equal to left side of the equation
now as per left side of equation its dimension is same as length or meter
now we can say it should be meter on right side also
similarly for other term we have
so above are the dimensions of b and c
