EXERCISE 7 - Rotational Kinematics and circular motion 1. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°‚ 30 rad‚ and 30 rev‚ respectively? 2.1m‚ 1.2x102 m‚ 7.7. x102m 2. A centrifuge in a medical laboratory rotates at an angular speed of 3 600 rev/min. When switched off‚ it rotates through 50.0 revolutions before coming to rest. Find

Dynamics describes the relationship between force and motion. Force? What is it? Put in simple terms‚ a force is a push or a pull. It pertains to any influence that causes a change in an object’s state of motion. • Contact Force A contact force is produced when there is direct contact between two interacting bodies. • Long-Range Force A long-range force is produced when one body influences the state of motion of another body even if these two bodies are separated by empty space. • Concurrent Forces

HER FIRST BALL KATHERINE MANSFIELD EXACTLY when the ball began Leila would have found it hard to say. Perhaps her first real partner was the cab. It did not matter that she shared the cab with the Sheridan girls and their brother. She sat back in her own little corner of it‚ and the bolster on which her hand rested felt like the sleeve of an unknown young man’s dress suit; and away they bowled‚ past waltzing lamp-posts and houses and fences and trees. "Have you really never been to

law of motion: For every action‚ there is an equal and opposite reaction. How this applies to our bottle rockets that we constructed‚ is that when we release‚ the water and air pressure comes out of the bottom. That pushes against the ground‚ the equal and opposite reaction is the earth pushing back up. Whatever object has less mass moves. In this case‚ the rocket has less mass than what it is pushing against; the earth. When we created our rockets‚ we had to keep all 3 laws of motion in mind

Newton’s second law of motion (Car vs Suv) According to newton’s second law of motion‚ Acceleration is produced when a force acts on a mass. The greater the mass is‚ the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied‚ the acceleration is directly proportional to the force‚ as an example‚ if pushing on an object‚ causing it to accelerate‚ and then you push

Case Study- Research in Motion (RIM) “Leading the Way the World Communicates” “It is the partnership and teamwork that underpinned the company and transformed the world!” The blackberry has challenged a number of very basic concepts in work and life. It eliminates distance and time and challenges the boundaries between work and home. It has enabled us to do things that would have been impossible 10 years ago. As a company itself RIM breaks the status quo by encouraging teamwork‚ empowering

SATELLITE TV: THE CRYSTAL BALL THAT OPENED NEW NARRATIVES OF REALITY Abstract The world around us is being constantly studied‚ analysed‚ made ‘sense’ of‚ categorised‚ named and assigned meaning. This human endeavour invariably leads to the formation of the amorphous entity called ‘Reality’. The introduction of Satellite TV channels and the introduction of 24 hours News channels that broadcast directly into millions of households around the world‚ without little or no State control has led to the
