peace-keeper in the world stage. (Red Poppy Field, by Irina Sztukowski, 2012) Poppy is a kind of plant that can grow up to 4 feet tall and that often blooms in late spring to early summer. (Simon, Chadwick, and Craker, Herbs: An indexed bibliography). Its recognition as a symbol of remembrance of war originated from the poem “In Flanders Fields” by the Lieutenant Colonel John McCrae. In the poem, he wrote “In Flanders fields the poppies blow Between the crosses, row on row,

Induction – Magnet through a Coil Activity P30 Purpose: Electromotive forces can be induced in a coil by changing the magnitude of the magnetic field within the coil, changing the area of the coil, or changing the angle between the magnetic field and the area of the coil. This lab used the first method of changing the magnitude of the magnetic field by dropping a magnet through a coil in order to induce an electromotive force. The EMF was measured as the magnet fell. The integral of EMF versus

devices are increasing rapidly in present and mainly for cordless devices or which has unmanageable wire connections. This technique passes electromagnetic energy to the portable devices when it is placed close to the wireless charger. magnetic field by passing alternating current through it for which there is a voltage induced in the receiver. I. INTRODUCTION In 1900 June Nikola Tesla introduced the concept of wireless charging. During 1891 to 1904 using Tesla coils (generates high AC voltage)

mathematical expressions. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current and Voltage Laws, which govern the currents entering and exiting

Recall our main theorem about vector fields. Theorem. Let R be an open region in E2 and let F be a C1 vector field on R. The following statements about F are equivalent: (1) There is a differentiable function f : R → R such that ∇f = F. (2) If C is a piecewise C1 path in R, then C F · dx depends only on the endpoints of C. (3) C F · dx = 0 for every piecewise C1 simple, closed curve in R. Furthermore, statements (1)–(3) imply (4) curl F = 0, and (4) implies (1)–(3) when R is simply connected

Outline a programme of field of fieldwork and research that you would undertakes to investigate rates of coastal retreat (15 marks) Fieldwork is the collection of primary data carried out at the location in the field. Research is secondary data and archival research normally carried out before or after investigation in the field. Coastal retreat is the removal of sediment from the shoreline/erosion resulting in the coastline moving back. During the investigation it would be important to consider
