An electron gun fires electrons into a magnetic field directed straight downward. Find the direction of the force exerted by the field on an electron for each of the following directions of the electron’s velocity: (a) horizontal and due north; (b) horizontal and 30° west of north; (c) due north‚ but at 30° below the horizontal; (d) straight upward. 2. (a) Find the direction of the force on a proton moving through the magnetic fields in Figure 1‚ as shown. (b) Repeat part (a)‚ assuming the moving

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre

equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring‚ while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However‚ due to errors in the experiment‚ the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating that all the forces are in

Genocide Paper I personally think genocide is wrong in every way you can think of. Why would anyone want to deliberately kill a group of people based on race or ethnicity? There have been much genocide to take place around the world‚ but some are better known than others. Some people have different theories on why genocide takes place. I think that genocide occurs for a couple reasons. The leaders of the genocide may feel that the group they are eliminating could be a potential threat somehow.

These changes are perceived to bring instability into the social structure5 and are resisted leading to moral policing India.

............................... 7 AIM To show that three forces acting upon a body‚ in equilibrium‚ may be represented by a triangle of forces. (Vector addition) INTRODUCTION With this experiment we will show that a body in a state of equilibrium‚ with three forces acting in a singular plane. The following conditions must be met: * Moment of all three forces must pass through the same point. * Magnitudes of the forces can be represented by the sides of a triangle‚ each as a vector

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

story‚ “The Use of Force” written by William Carlos Williams‚ a doctor is summoned to a family’s household for a sick child named Mathilda. She is said to have and show signs of Diphtheria‚ but she fights to hide it. In order to treat Mathilda‚ the doctor needs to get a throat culture forcefully. She attacked the doctor once causing his frustration and determination to increase. When he does‚ the doctor has a sense of relief but Mathilda feels violation. The doctor’s use of force is similar to Anne

ABSTRACT COOKSON‚ EDWARD JAMES. Development of the Metal Foam Electrical Resistance Heater. (Under the Direction of Dr. Albert Shih.) This thesis presents a novel concept using a radial heating element made from porous Fe-Cr-Al metal foam in an air heater. Electrical resistance heating has been used extensively to convert the electrical energy into thermal energy. An analytic heat transfer model is first developed to estimate dimensions of the heating element. Four prototype Fe-Cr-Al metal

Bio-112 Antibiotic Resistance Experiment Lab Partners: March 10‚ 2010 When we initially started the bacteria antibiotic experiment on February 10‚ 2010 our team selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build towards this antibiotic. When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked
