humankind, that in the evolution of the species the human family separated in a sense that one branch of the family stopped its evolutionary path and simply depended upon the central nervous system as the total machinery for understanding reality. Whereas, the root of the family continued its path and not only evolved a central nervous system but developed what I called at that time an essential melanic system. And that I even went so far as to try to develop a little formula and suggested that CNS + EMS = HB. CNS (Central Nervous System) + EMS (Essential Melanic System) = HB (Human Being). That the central nervous system combined with the essential melanic system is what makes you human. That, in fact, to be human is to be Black. To be human is to be Black.

I get that the MandleCandle uses patented microelectronic technology driven by heat from an environmentally friendly Lithium battery, BUT HOW? Does it rely on different densities of differently coloured waxes/fluids...bit like a lava lamp? I've only seen them on telly, so I wouldn't know! Ta! x

These are the questions that we need to answer in our problem set and case study. Please help!

1. The new EV-1 electric car makes use of storage batteries as its source of energy. Its mass is 1300 kg and it is powered by 26 batteries, each 12 V, 52 A•h. assume that the car is driven on the level at an average speed of 40 km/hr and the average friction force is 240 N. Assume 100% efficiency and neglect energy used for acceleration. Note that no energy is consumed when the vehicle is stopped since the engine doesn’t need to idle. (a) Determine the horsepower required. (b) After approximately how many kilometers must the batteries be recharged?

2. A nerve is stimulated with an electric pulse. The action potential is detected at a point 3.40 cm down the axon 0.0052 s later. When the cation potential is detected 7.20 cm from the point of simulation, the time required is 0.0063 s. What is the speed of the electric pulse along the axon? Why are two measurements needed instead of only on
