Describe the adjustments you made to the Rube Goldberg device in order to keep the flow of energy going. (6 points) 3. At the end of the lab all of the matter (such as the string‚ the ball and the books) stayed in the area. The potential energy‚ that was stored in the ball on the high shelf and suspended weights as well as the stored mechanical energy of

membrane potential when extracellular K+ concentration is increased? -The resting membrane potential will become more positive when K+ concentration is increased. 2. Explain why the resting membrane potential had the same value in the cell body and in the axon. -The resting membrane potential has the same value in the cell body and the axon because the typical resting membrane potential is the same throughout the entire neuron. 3. Describe what would happen to the resting membrane potential if the

amount of Potential energy at the start and how much kinetic energy it had when it reached the bottom. Things we learned that was relevant to the lab were what Potential Energy and Kinetic Energy was. Potential Energy is stored energy due to objects relative position‚ while Kinetic energy was energy of motion; amount of energy depends on objects mass and velocity. The lab with the roller coaster showed examples of when the coaster was at the highest point that it had more Gravitational Potential energy

Based on Criteria’s of Evaluating Venture Opportunities there are several key indicators that shows that Zipcar is indeed a high potential venture. Below are the criteria in brief 1.0 Industry & Market Market: The revolutionary concept certainly provides an alternative to public transport. Furthermore the car sharing concept is really useful for the public in a overcrowded city with limited parking & expensive parking fees. This is clearly not an untouched segment because there are other 2 competitors

Research An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force‚ expressed as the weight of the object. The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum‚ this would be

build up this momentum(potential energy) the train needs to get to the top of the hill. The lifting mechanism is a long length of chain that runs up the hill under the track. The chain is a fasten loop and the chain on the bottom is ran by a simple motor.The chain dogs are sturdy hinged hooks that catches on to chain links then at the summit the chain dogs are released. The catapult launch lift sets the train in motion instead of pulling the train up building potential

nerve fibers or axons allowing the examination of the action potentials through the movements of the nerve. The sciatic nerve axons are different in structure and function. Axons with large diameter perform action potentials faster than axons with small diameter. The sciatic nerve has a lot of properties that make it to be a good candidate for this

Task 2 1. The maximum potential energy would be at the highest point of the coaster which is 61m at point A. The equation for potential energy is: PE=mgh. Throughout the trip‚ the mass and gravity are constant variables while height is a changeable variable. Therefore‚ if the height is increased then so is the potential energy. The maximum kinetic energy is at B. This is because as the cars lose height‚ they speed up (v=d/t). Therefore‚ most of their original potential energy (due to the height)
