Did you know that the human heart pumps about 182 million liters of blood throughout your whole lifetime? (99 Quick and Fascinating Facts) The human body is full of mysteries that most of the world doesn’t know about. Your body does very strange things that you would never think could happen‚ while others are totally believable. This paper is about three of those facts that I found interesting and unbelievable myself. Lightning can give you skin designs? Who would have thought! The designs that

ity C&G 2330 202 REVISION QUESTIONS The relationship between the mass of a body (m)‚ the applied force to the body (F) and the acceleration of the body a. is given by the formula: a. Force = mass x acceleration‚ F = m x a b. mass = Force x acceleration‚ m = F x a c. acceleration = mass x Force‚ a = m x F d. acceleration = mass / Force‚ a = m / F answer: a The SI unit of time is the second. Express 0.00001 seconds in a suitable sub multiple: a. 10 milliseconds‚ 10 ms b. 100 milliseconds

Eddy Current 1. The principles of eddy current testing depend on the process of electromagnetic induction. 2. This process includes a test coil through which vary or alternating current (AC) is passed. 3. A varying current flowing in a test coil produces a varying electromagnetic field around the coil‚ As shown in this diagram Amperage * # of coils= strength of magnetic field 4. The electromagnetic field produced around the coils is directly proportional

New technological advancements in the field of myoelectric prosthetics have led to development of hands with multiple degrees of freedom. Nonetheless‚ these devices are still inadequate in terms of performance‚ stability‚ aesthetics‚ and affordability. Anthropomorphic hands such as iLimbTM and BebionicTM have received media attention—yet‚ they are not as consumer friendly as advertised. The use of servos‚ rather than DC motors‚ in this new prototype proves to be a more viable option when controlling

A>B>C A being the brightest 2. How do you predict that changing the direction of the current by reversing the connections to the battery in Figure 2-1 would change the rankings in (1)? I don’t think it will change at all. The brightness should be the same in diagram b and diagram a it should also stay
