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

Question 1(10 marks) Comment the following statements (a) The volume coefficient of thermal expansion of water is negative for temperatures in the range 0 to 4 °C. (b) The triple point of water‚ 0.01 °C‚ and 611.73 Pa‚ is one of the primary fixed points on the Kelvin absolute temperature scale. (c) The volume coefficient for the thermal expansion of a solid is twice the linear coefficient for thermal expansion. (d) A temperature of 26.85 °C is the same as 300 K. (e) The surface temperature

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

things in the field of the health care profession. One of the lessons they taught to us is about Manual Handling. When the topic was introduced to us‚ the first thing that came to my mind is that manual handling is all about how to lift or transfer a patient from one place to another (for example: bed to chair). But then‚ when my clinical instructor started the lecture‚ I’ve come to realized that manual handling does not only mean carrying‚ lifting‚ or transferring a patient from place to place.

force of gravity. - Surfers rely on weather conditions‚ their equipment‚ safety‚ and their techniques. - Low tide waves are faster‚ stronger‚ and tend to close-out - High tide waves are slower‚ and lose force. • Surfing has a wide background of physics • The amplitude in a wave grows as energy is added to it‚ and it shrinks when energy is subtracted from it. - The speed of the wave‚ and the buoyancy of the board is what keeps the ability to ride the wave and maintain speed. - When you are surfing
