Mother’s Day is a celebration honoring mothers and motherhood‚ maternal bonds‚ and the influence of mothers in society. It is celebrated on various days in many parts of the world‚ most commonly in March or May. It complements Father’s Day‚ a similar celebration honoring fathers. The celebration of Mother’s Day began in the United States in the early 20th century; it is not related to the many celebrations of mothers and motherhood that have occurred throughout the world over thousands of years

velocity for the travelling marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed along the radius). As ∆t approaches 0‚ ∆v becomes exactly radial

“A happening is for those who happen in this world‚ for those who don’t want to stand off and just look. If you happen‚ you can’t be outside peeking in. You’ve got to be involved physically” (Kaprow‚ ‚ )Allan Kaprow acted as central figure in the repositioning the art world of 1960’s‚ his Happenings were a form of impulsive‚ chance driven‚ non-linear action‚ that revolutionized performance art. Although Kaprow began as a painter‚ his curiosity shifted in the mid 1950’s to the theoretical

Chapter 8- Circular Measure Additional Mathematics Module Form 4 SMK Agama Arau‚ Perlis CHAPTER 8- CIRCULAR MEASURE 8.1 RADIAN 1. In lower secondary‚ we have learned the unit for angle is degree. In this chapter‚ we will learn one more unit for angle that is radian. P r O 1 radian r Q 2. When the value of the angle 1 radian‚ then the length of the arc is equal to the length of the radius. 3. From this information‚ we can deduce that: r 1 rad r = 360 2πr 1 rad = r 2πr × 360 2π rad

numerological properties‚ seeking perfect and amicable numbers. (O’Connor & Robertson‚ 2009) In 300 BC‚ Greek mathematician‚ Euclid of Alexandria proved and documented in his Book IX of the Elements that prime numbers were infinite. He started with what he believed to be a comprehensive list of prime numbers‚ created a new number‚ N‚ by multiplying all of the prime numbers together and adding 1. This resulted in a number not on his list and not divisible by any of his prime numbers. N therefore

Research topic: The obesity epidemic: What’s Really Happening? Research problem: There are many people to blame‚ such as food industries or the government but individuals need to consider themselves in taking personal responsibility of themselves. Hypothesis: The rising prevalence of obesity has become an epidemic combining both of them in sociable interactions. Although obesity is generally often identified to stress and lower social economic status. I consider that obesity‚ and perhaps many

1/22/07 The Fragile Economy of the 1920’s and 30’s Post WWI and the Roaring Twenties Prior to the roaring twenties the global economy was unstable. World War I had created fragile trading bonds between the U.S. and many countries‚ war reparations needed to be paid by the countries that lost the war‚ countries such as Germany and Great Britain were indebted to the United States‚ and‚ as we know well‚ wars cost money. The economy was weakened and the developments made in the 1920’s didn’t help to

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific
