LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity

BOOM’ S PROBLEM PS 4.3 – Torque (Rotational Equilibrium) Problems 1. A crane supports a 3.0 kN weight as shown. The crane’s boom is 8.0 m long and is at an angle of 30˚ from the horizontal. If the hydraulic support is attached to the boom 2.0 m from the bottom of the boom‚ then: a) what is the compressional force in the hydraulic? b) what is the magnitude and direction of the force on the pin at the bottom of the boom? a) ∑Torque = 0 F cos 30˚ x 2.0 = 3000 cos 30˚ x 8.0 F = 24

Next would be how you hold the guitar while sitting or standing. This is a very simple technique and very hard to do incorrectly. The back of the guitar will be flush against your midsection. If the guitar covers most of your torso‚ then it may be too big. If it is too big‚ it will be difficult to play smoothly. Now that you know how to hold the guitar‚ and where to put your hands‚ you should know how to put the strap on the guitar‚ simply referred to as “strapping the guitar”. Both ends of the strap

PHYSICS‚TECHNOLOGY AND SOCIETY. Technology and society or technology and culture refers to cyclical co-dependence‚ co-influence‚ co-production of technology and society upon the other (technology upon culture‚ and vice-versa). This synergistic relationship occurred from the dawn of humankind‚ with the invention of simple tools and continues into modern technologies such as the printing press and computers.
