Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl. Momentum conservation equation:

In the novel Girl‚ Stolen by April Henry‚ the main theme is "Do not act on impulse. Think things through." This means that don’t do the first thing that comes to mind. Throughout the book‚ the characters show multiple examples of that. One example of someone being an example of why to not act on impulse is Griffin. If he didn’t take Cheyenne’s step-mother‚ Danielle‚ car Griffin wouldn’t be in a position of kidnapping a teenage girl. "Look‚ it’s an accident you’re here. I just wanted the car‚ not

concern about their body weight. Impulse-control disorders: psychological disorders in which people repeatedly engage in behaviors that are potentially harmful‚ feeling unable to stop themselves and experiencing a sense of desperation if their attempts carry out the behaviors are thwarted. Before they act on their impulses‚ these individuals experience tension and anxiety that they can relieve only by following through on their impulses. After acting on their impulses they experience a sense of pleasure

Introduction Neurons (also known as neurons‚ nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons. One extension is different from all the others‚ and is called

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

Marble-lous Momentum Question: What happens to momentum when one marble collides with other marbles? Hypothesis: If a marble collides with increasingly more marbles‚ then the momentum will be transferred more slowly to the final marble‚ because momentum is conserved through an inelastic collision‚ but a longer distance will have be traveled by the kinetic energy. Independent Variable: The number of marbles. Dependent Variable: The momentum of the first marble and final marble. Control Variables:

ADAM BAIN AND THE PRICE MOMENTUM STRATEGY In February 1995‚ Adam Bain‚ investment advisor in the London‚ Ontario branch of RBC Dominion Securities Inc. (RBC DS)‚ was considering whether or not to implement a price momentum strategy for his clients. Trend and Cycle‚ DS’s technical research department‚ had recently circulated a copy of a study which described a simple price momentum model and referred to its “startling results” based on back testing the strategy over a 15 year period. The Trend
