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

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

MYP 8 (1) Sabrina Group member: Lucy‚ Angel Research question: How does the air force affect the falling place? Hypothesis: If the air force is lower/higher than the falling place is closer/further because in some place air force let parachute fly more further/closer when the air force is lower/higher. Variables: Independent variable: air force. Dependent variable: distance of parachute (measure with ruler) Control variable: the

Importance of Physics in the Modern World By PatrickB‚ eHow Contributor Physics is second only to mathematics in the purity of its principles. Physics describes how the natural world works through applied mathematical formulas. It deals with the fundamental forces of the universe and how they interact with matter looking at everything from galaxies and planets to atoms and quarks and everything in between. All other natural sciences stem from physics. Chemistry is essentially applied physics and biology

The invention of the airplane was a major step forward for warfare. During the lead up to World War One airplanes where only allowed for surveillance and they were forbidden to drop or shot any projectiles but soon people realized how valuable planes could be in combat so they started producing these war weapons just before the beginning of the war. The first bombing was delivered by the Italian in November 1911 just before the beginning of World War One. Which was followed by the first Aerial dogfight
