the field is given by the direction of that force. Electric fields contain electrical energy with energy density proportional to the square of the field amplitude. The electric field is to charge as gravitational acceleration is to mass and force density is to volume. 1. Suppose that two point charges‚ each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them. Given: Q1 = 1.00 C Q2 = 1.00 C

Ultrasonic sensors generate high frequency sound waves and evaluate the echo which is received back by the sensor. Sensors calculate the time interval between sending the signal and receiving the echo to determine the distance to an object. This technology can be used for measuring: wind speed and direction (anemometer)‚ fullness of a tank and speed through air or water. For measuring speed or direction a device uses multiple detectors and calculates the speed from the relative distances to particulates

Support for affirmative action in employment At the national level‚ the survey results indicate there is broad support for affirmative action as a form of redress in the labour market (Fig. 1). Over the 2003–2009 period‚ the share of adults in South Africa agreeing or strongly agreeing that there should be racial- and gender-based affirmative action in the workplace ranged in a narrow band between 60 and 70%. More so‚ the 2006 SASAS survey round found that 68% of participants supported the preferential

ENGR. JAY S. VILLAN‚ MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have around the house‚ and anyone who plans on doing electrical repairs should most definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in
