To Explain:The source of energy for the bulbwhen a person rides along a flat road.

Answer to Problem 11SSC
Mechanical energy is a source of the energy forthe bulb when you ride along a flat road.
Explanation of Solution
Introduction:
A device, which changes motive power (or mechanical energy) into electrical power (used in external circuit),is called an electric generator. Electric generators work on the principle of
In order to generate electricity for the light attached to the bicycle some mechanical energy needs to be supplied to the dynamo in the light source. The mechanical energy for the dynamo is obtained from the moving wheels of the bicycle. The dynamo uses that mechanical energy to convert the form of energy from mechanical to electrical.
Conclusion:
The dynamo in the light source uses the mechanical energy from the moving wheel and converts it into electrical form.

Your supervisor has asked you to analyze emergency procedures for extravehicular activity (EVA), when the astronauts leave the International Space Station (ISS) to do repairs to its exterior or perform other tasks. In particular, the scenario you are studying is a failure of the manned-maneuvering unit (MMU), which is a nitrogen-propelled backpack that attaches to the astronaut's primary life support system (PLSS). In this scenario, the astronaut is floating directly away from the ISS and cannot use the failed MMU to get back. Therefore, the emergency plan is to take off the MMU and throw it in a direction directly away from the ISS, an action that will hopefully cause the astronaut to reverse direction and float back to the station. You have the following mass data provided to you: astronaut: 78.1 kg, spacesuit: 36.8 kg, MMU: 115 kg, PLSS: 145 kg. Based on tests performed by astronauts floating "weightless" inside the ISS, the most…arrow_forward
