1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving then when the sound gets closer‚ the volume will increase and when the sound passes by you‚ the volume will start decreasing. 2. Select the boy icon. Select the

ROA‚ ANNA MARIA D. BA PSYCHOLOGY 1 Physics and Psychology—Relationship Status: It’s Complicated but Related One way or another‚ all things in life are related to one another. The same goes with Physics and Psychology. These two Sciences are different in a lot of ways but are also similar in certain aspects. Physics is the branch of Science concerned with the nature and properties of matter and energy. Psychology‚ on the other hand‚ is the scientific study of the mind and its functions

Business at the Speed of Thought by Bill Gates In 1999‚ with the release of his book “Business at the Speed of Thought” Bill Gates attempted to enlighten the world to the fact that in order to succeed and become leaders in the future‚ businesses throughout the world would have to implement digital technology. The book itself is written entirely from Mr. Gates’ point of view. He wrote it in response to a number of requests from multi level business managers‚ organizational and corporate leaders

has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly. 3. For the same force‚ why does a long rifle impart more speed to a bullet than a short pistol? The long barrel means that

1) A 4-kg mass moving with speed 2 m/s‚ and a 2-kg mass moving with a speed of 4 m/s‚ are gliding over a horizontal frictionless surface. Both objects encounter the same horizontal force‚ which directly opposes their motion‚ and are brought to rest by it. Which statement best describes their respective stopping distances? (A) The 4-kg mass travels twice as far as the 2-kg mass before stopping. (B) The 2-kg mass travels twice as far as the 4-kg mass before stopping. (C) Both masses travel the

The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost

new resources appropriately? Are we getting our moneys worth? Bill Gates says we are not and suggests a new model he calls a digital nervous system as a way to maximize value from technology and information. In his book‚ Business @ the Speed of Thought‚ Gates attempts to make the case that most organizations do not get the maximum out of their technology. He asserts that most organizations have the wrong mind-set about how information should be handled and distributed within an organization
