1. Two ships P and Q are moving along straight lines with constant velocities. Initially P is at a point O and the position vector of Q relative to O is (6i + 12j) km‚ where i and j are unit vectors directed due east and due north respectively. The ship P is moving with velocity 10j km h–1 and Q is moving with velocity (−8i + 6j) km h−1. At time t hours the position vectors of P and Q relative to O are p km and q km respectively. (a) (b) (c) Find p and q in terms of t. (3) Calculate the distance

Kinematics of linear motion (5 hours) 1 2.0 Kinematics of Linear motion is defined as the studies of motion of an objects without considering the effects that produce the motion. There are two types of motion: Linear or straight line motion (1-D) with constant (uniform) velocity with constant (uniform) acceleration‚ e.g. free fall motion Projectile motion (2-D) x-component (horizontal) y-component (vertical) 2 Learning Outcome: 2.1 Linear Motion (2 hour) www.kmph

“Discuss the key differences between ‘individual racism’ and ‘institutional racism’. Give examples to illustrate your argument”. The Oxford English Dictionary describes racism as “prejudice‚ discrimination‚ or antagonism directed against a group or individual of a different race based on the belief that one’s own race is superior”. It is significant when concerning oneself with the discussion of racism that a clear and concise distinction is made between the two different types of racism. Firstly

In 1775‚ Patrick Henry introduced a proposal to the Virginia Convention to form a local militia to be prepared to fight the British. In order for his proposal to pass and for his vision to become a reality‚ he had to persuade the members of the Virginia Convention to arm themselves as patriots to fight the British if they did not meet their demands. To do this‚ he had to appeal to their emotions‚ logic and many other aspects in order to make his speech effective and to obtain the goal that he wanted

policy gave them what they wanted. In the 1930s‚ the Axis Powers often demand for lands and Britain and France often appeased them and did not take any actions. This result in making the Axis Powers more aggressive. There were several examples of Appeasement Policy between Britain and France in the 1930s. One of the most representative ones was the German occupation of Czechoslovakia. As there were a large population of German living in Sudetenland in the western part of Czechoslovakia‚ and Sudetenland

Give life‚ give blood! Imagine your mom‚ dad‚ son‚ and or‚ daughter in a tragic car accident‚ or diagnosed with cancer. The only chance of survival is a blood transfusion‚ because your blood type is not a match. We all expect that blood will be there for us or a loved one; however‚ hardly a fraction of people that can give blood actually do. At some point of our lives we may face a time of susceptibility where we will need blood. The day-to-day need for blood never ends. Statistics

Introduction The purpose of this experiment is to determine whether a change in mass affects the acceleration of the cart. The independent variable is the mass of the weight and the dependant variable is the acceleration. I do not think there is a control in the experiment because we do not know an absolute result with any of the masses of the weight. Besides‚ if we used 0g as our control‚ the cart won’t even move. Hypothesis Under these conditions I believe that the results shown in the distance
