force of the expanding gases from the gunpowder is able to push for more time on the bullet (since the push will continue as long as the bullet is in the barrel). Impulse = (Applied Force)*(time) 4. When you are in the way of a moving object and a collision is sure to occur‚ are you better off decreasing its momentum over a short time or over a long time? Explain. The amount of force you will feel is the same as the force you apply to the object. So if you decrease its momentum over a long time‚ less

problems the hub caused to the network. To start the hub receives data packet from a sending computer and it sends out to all the computers except the senders on the network. This can cause a collision on the network if more than one piece of data packet is sent across the wire. CSMA/CD helps with the collisions by using a system where before data packet is sent‚ it can inspect the wire for data packet‚ and if there is data packet on the wire it sets a random timer and investigates again to find out

Define the term activation energy (Ea). Describe the collision theory. Students should know that reaction rate depends on: Collision frequency Number of particles with E > Ea Appropriate collision geometry or orientation Predict and explain‚ using collision theory‚ the qualitative effect of particle

Cars race down the road at uncontrollable speeds that cause tickets‚ accidents‚ and sadly death. Speed limits are a must for traffic control‚ for safety in neighborhoods and for avoidance of collisions. Traffic control establishes a set of rules and regulations that people rely on to help avoid collisions and other hazards. With almost 160 million motorists and 3.8 million miles of public roads in the United States‚ traffic control on the highways is an important aspect of daily life. Without the

on how to act in order to advise the audience how cultural collision will affect people’s lives. The author’s treatment of Gogol having trouble on what to do throughout the novel relates to the overall meaning of the novel showing that people who have different cultures have a difficult time adjusting to their new home. Colliding cultures do not just happen during movies or novels‚ people inevitably face this today. Cultural collision occurs when one act from a culture happens to be different

opinions can often cause cultures to collide when a doctor is summoned to treat an individual of a different culture than their own. Anne Fadiman’s book‚ The Spirit Catches You and You Fall Down‚ tells the story of an epileptic Hmong child and her collision of two cultures. Lia Lee began suffering seizures at a young age and was diagnosed with epilepsy by American doctors. Her family however believed her illness was caused by soul loss (Fadiman 21). While at the hospital‚ Lia’s family was unable

Chemical Kinetics in the field of Chemistry‚ the Collision Theory plays a large role. The theory states that the more collisions that occur in a system‚ the more likely combinations of molecules will happen. Also‚ more collisions means more combinations of molecules to occur which will consequently speed up the reaction and the rate of reaction (Bursten 492). Another factor in reaction rates in the concentration of particles. Similar to the Collision Theory‚ the more particles there are the greater

Many things can occur during a during a cultural collision‚ some can be bad‚ others good. In the book Things Fall Apart‚ by Chinua Achebe‚ the main character‚ Okonkwo‚ had to make many decisions throughout his lifetime because of the challenges that were thrown at him. Okonkwo’s sense of identity was disrupted when he was challenged with the introduction of Western ideas. He continually tries to fight the changes happening within the Ibo society. Okonkwo’s change in his sense of identity was due

This reaction occurs due to successful collisions between particles of reactants. Collision theory helps to explain how a chemical reaction occurs‚ collision theory states that atoms ions and molecules must collide with each other with the correct orientation and the correct amount of activation energy in order for a reaction to occur‚ if they do
