24-1 - Assignment Example Particle of matter move continuously. Particles of matter attract each other. Particle of mater has space between them. (2.9). It is used to compute moments, magnetic fields direction and loosen screws .it is a form of mnemonics used to understand physics. Such can be done by holding both hands together; palm up with the fingers curled for the curl of fingers representing a rotation following the axis consecutively one after the other along the right thumb or left. (2.10). The magnetic force usually acts at right angles to the charges motion thus the magnetic force cannot work on the charge. The B field at that instance either speed up or slow down the moving charge and only change the direction the charge is moving. The path taken by moving charge in a constant magnetic field is that described by helix with its parallel axis to the direction of the magnetic field (Tipler 477). 2.11. Cauchys equation gives the relation between the refractive index and wavelength of light. The equation provides an empirical relationship that occurs in the refractive index and wavelength of light for a particular transparent material. (4.1). Given values are V=3.5v, using hc/ Ä §=Ø+Vq. Make q subject of the equation. Ø=hc/ Ä §-vq.{(6.64*10^(-34)*3.0*10^8)/4.5*10^(-7)m}={4.426*10^(-27)- (0.35*1.6*10^(-19)}=2.766*10^8v-1v=2.765*10^8v but W=-eØ-Ef={(- 1.6*10^(- 19)*2.766*10^8)-0.56*10^(-19)v}=-4.44256*10^(-11)- 0.56*10^(-19)v={- 4.4425*10^-11/1.6*10^(-19)}=2.7765*10^8Joules. (4.2). Momentum (p)=hf/c or h/Ä §, Also E=hf or hc/ Ä §, whereby E=25eV, h=6.64*10^-34., c=3.0*10^8m/s. Ä §=hc/E={(6.64*10^(- 34)*3.0*10^8)/25eV}=0.7968*10^(-26)m. but p=h/

ELL Learners Today Research Paper Example | Topics and Well Written Essays - 1000 words

ELL Learners Today - Research Paper Example These are (a) imitation theory, (b) reinforcement theory, and (c) active construction of grammar theory (Lindsay, Roberts, & Campbell, 2005; College of Education, 2010; Mixed Sources, 2007). Imitation theory follows a procedure where a child is permeated to hear speech sounds and be encouraged to imitate it (Lindsay et. al, 2005). For instance, English couples teach their child to speak English or a Japanese couple would teach their children Niponggo as its native language. In this imitative process, first learners would encounter problems and errors which are generally acceptable, predictable and consistent (Ontario Ministry of Education, 2007). Reinforcement theory refer to a process of language acquisition where adults take the role of supporting or coaching the children in the learning processes, and are constantly appraising the child’s communicative progress through affirmation, appreciation, and by correcting children’s errors either by form, by statement’ s content and/or the truthfulness what a child conveyed (OME, 2007). Moreover, in the active construction of a grammar, a child start to learn formal statement construction that is sensitive to lessons learnt from linguistic inputs. This means that the children are already receiving language input following the lessons they learned from adults or from their coaches (OME, 2007). In this stage, they can start to communicate formally with others in better form or sentence construction and they are able to convey meanings clearly using better language performance (OME, 2007). 2) How can we as teachers ease new ELL students into our classrooms in ways that help them become a contributing member of our classroom community? What do you plan to do to help new ELLs feel a part of your classroom from the beginning? To help learners ease in the learning process, teachers must develop a learning environment that will permeate continued development of children language
