Lifecycle of Human Being



The four focal phases of Human cycle comprise birth and early stages, childhood, youth and maturity. Birth commonly takes place between insemination and 40 weeks following insemination whereas embryonic stage lasts from birth through the first year of life. On the other hand, babyhood is between the ages of one and ten and youth is between 12 and 18. Lastly, adulthood is the lengthiest and it lasts from age 18 to old age.





The basic eight stages are:

  1. Prenatal
  2. First year of infant’s life
  3. Toddler
  4. School age
  5. Adolescence
  6. Adult
  7. Lactating female
  8. Mature adult

Life cycle and age  to be in that life cycle:

  1. Prenatal :25- 40 years
  2. First year of infant’s life:0 to 12 months
  3. Toddler:1 – 2 year
  4. School age:3 to 12 years
  5. Adolescence: 13 to 19 years
  6. Adult: 19 to rest of the life
  7. Lactating female: 18-40 years
  8. Mature adult: 21 years to rest of the life

Describe nutritional challenges associated with that particular lifecycle.

Birth to 12 months

  • Begin and continue breastmilk or formula.

4 to 6 months

  • Start cereals.
  • Start vegetables, fruits, and juices. Use real fruit juices, not a sweetened fruit drink. Use commercial baby food or unseasoned strained and mashed table foods.

5 to 6 months Babies can sit up in a high chair with support.

  • Start plain meats which have more iron and protein than combination dinners or soups.

6 to 9 months

  • Start finger foods. Teething crackers and other foods such as toast, or dry, unsweetened cereal are good choices.
  • Practice using a cup to drink milk, juice, or water as an adult holds it. Two handle cups and a spout are easiest to use.

9 to 12 months

  • Start table diets that are well sliced or crushed. Avoid giving hard foods, such as nuts, popcorn, or raw vegetables; babies easily choke on these items.

Infancy and Early Childhood:

Energy. While most adults necessitate 25 to 30 calories per kg, a 4 kg kid requires more than 100 kcals/kg (430 calories/day). Children 4 to 6 months who weigh 6 kg require roughly 82 kcals/kg (490 calories/day). Liveliness needs remain high through the early influential years. Children 1 to 3 years of age require around 83 kcals/kg (990 kcals/day). Energy supplies decline afterward and are based on weight, height, and physical activity.

Copyright Basics

Today more than ever, photographs and other visual media are at our fingertips. Whether it’s through Google Images or Flickr or AceMyHW, we have endless visual media available for us to use. Or, do we?


Watch the video Copyright Basics


Then, in a 2 page paper, examine the benefits and challenges associated with having so many visuals available to us today. Describe the possible ethical and legal implications of using these photos, and explain how these issues can be avoided.





Photographs are collection of memories, places and events. Now days we get Photographs of all places, memories and celebrites on Google images and Flickr or any other website. People are very much fond of photographs of Places, celebrities and Artistic photos. Now days we can see, Photos and Videos are at fingertips we can download it at the help of one click.

With the advancement of the Paparazzi, a normal photograph is not a photograph any more it is being sold as millions to other big news agencies and daily agencies.

There are many benefits of the photo world now a days, the most advantage we have is that we can upload our photos and keep it safe on the internet, without the public viewing of the photographs.

The are many websites like Flickr, Instagram and etc. Where are storing more than 100 of GB of photos every day. The other most valuable aspect of the Photo world is the education that can be given through the photos.

Through the Photos we can teach children about the various aspects of Education. We can also search the paintings of Picasso, Da Vinci. The whole pictorial representation of the Century can be viewed by just clicking the Search button. We can view a variety of pictures from those of Hitler to Footsteps of Neil Armstrong. These are the most advantages of the Photos that we can view on the internet.

The major disadvantages we get from the photo world are MORE IN NUMBER.


There are also some explicit content shown of the web, which are very harmful to the children and the viewer’s searching the web.

The major harm the photo world does is to the celebrites and the respected people all around the globe. There are many news agencies and paparazzi, they follow the celebs and poke their privacy to take private photos of them and sell it out on the web, leaving them humiliated in front of the world.

The photos which can hurt religious sentiments, and can cause a furor

Should be banned before publishing, people publishing the photos on the net should be held in for publishing such controversial pictures.

The other legal step must be the photo sharing to remain private and confidential. There have been many photos of celebrities that have been leaked to cause harm to the people.

These are some advantages and disadvantes of the photo world on the internet,



Physics Problems PHY 101

  1. When object is tossed in the air, nothing affects its acceleration but the acceleration of gravity only. So, the source of the acceleration is the force of gravity solely.


The objects interacting with the ball is the hand that gives force to the ball to go upward.  Then as the ball is on the air, the force of gravity interacts with the ball that causes the ball to comes back to the ground and not move upward forever.

When a ball is tossed in the air, its initial velocity is zero

When given a force, it gains a velocity and go upward. The

object accelerates under the force of gravity .


here the objects interacting with the ball are the hand which gives the thrust and the gravitional force, due to which it comes back to the ground



  1. Supposedly an object in this motion should have not a horizontal acceleration because only the force of gravity acts on the object. So if only gravity acts on the object, only vertical acceleration is present. The possible source of the horizontal acceleration is an external force that affects the motion of the object, disabling it to accelerate in vertical only.

The gravitional acceleration = -9.8 m/s^2

Let  the ball is going upward with the velocity of  u m/sec e

Velocity through horizontal = v*cos x.

X is angle of the throw.

So ,

The observed acceleration in horizontal is zero.

The vertical acceleration is = -9.8 m/sec^2

The objects interacting here are the hand and the force of gravity.



  1. Yes the source of acceleration observed is the same with the answer in 1a. As you can see in the data the acceleration is almost close to the constant acceleration due to gravity which 9.8 m/s2.

When an object is dropped, it gains acceleration of the force of gravity.

So the height its falls its velocity Is zero

And acceleration is 9.8 m/s^2




For a tossed object


V = 3 m /sec^2.   Suppose

So ,  when going upwards  it  speed =  V = 3  -9.8 * t .

T  is  t time,

At when  v= 0  , its  drops due to force of gravity

So  it falls with positive acceleration  = 9.8 m/sec^2

So both are different




Data sheet  4



We know the equation of displacement

D = v(i)*t  + ½ * a *t ^2

Dy= v(i)y*t + ½* ay*t^2.


Where  dy= dx



We are doing average of three columns.

K                 m                        n                                 average

9.5755      9.6245              10.154+/- 1.57135             9.78+/-1.51715

Yes, all the data makes need to eliminate one .




2.c  7.757+/-4.556m/s2= aaverage

2d. No. The motion of the object should be always perpendicular whatever the forward horizontal velocity is. It is always independent with each other. Wherein by the equation of motion:

Vx=V0x ; constant all the time.

Vy=Voy+at; where velocity changes uniformly by 9.8m/s2 per second.

So, example if at t-1s, and initial velocity v0y=2m/s:


At t=2s;


So, clearly the vertical motion of the object will not be any affected by whatever horizontal motion is. It will always only be affected by the force of gravity.



2e. The mass of the object does not in any way affect the vertical acceleration of the system. The only possibility that causes its variation is the drag force since the system is not done in a vacuum. There would be some external forces dragging the motion horizontally. From the equation of motion also below, mass m has nothing to do with or it’s not included, meaning it is always independent of the mass of the object.





3a. Yes, same as the graph my data also has negative slope for both tossed and drop and almost same because as we all know the slope of a velocity-time graph is always the average acceleration of the object. Our acceleration is almost near to 9.8 m/s2 so for both tossed and drop data, so it is expected that we can same or almost same slope near to that constant value.

The velocity becomes relatively large negative as the object moves downward approaching to the ground and it becomes relatively large positive when it moves upward. Upward motion is positive velocity that increases uniformly with the acceleration and downward motion is negative.


3b. Yes, it will always stop at the top and velocity becomes zero. The moment it stop and velocity becomes zero at an instant where it already reaches its maximum height. This is due to the force of gravity that pulls the object downward. Without the gravitational pull any object suspended in air will continue moving in its direction of motion forever.


3c. the data points on the table is not very clear but you can do it the exact one I will just give you my approximation:

Drawing a horizontal line halfway from the minimum to maximum height meaning you are to draw from the graph from the center of the complete parabola then compute the time as:


∆t(above half height) =0.66s;  ∆t(below half height) =0.99s-0.66s=0.33s

∆t(total) =0.66s+0.33s=0.99s

The ball spends more time above half height because the height is bigger compare to the below that will affect the time of the motion of the object.
