How to apply the law of electric charges associating yourself from others and in choosing your partner in life.

In temperature measurement experiment, if three temperatures are considered (50 °C, -5 °C, and 20 °C) the measured voltage according to Peltier law, respectively will be (knowing that the ambient temperature is equal to 20 °C): Select one: a. Positive, zero, and positive. b. Zero, positive, and negative C. Negative, negative, and zero d. Positive, negative, and zero. In the Boyle's Law Demonstration experiment, the total volume of the measuring chamber is 1 liter and the total height is 200 mm. If the oil height in the measuring chamber is 50 mm then the corresponding air volume is equal to: Select one: AR 10:07 PM 4/16/2021

A metal spoon and a wooden spoon are left overnight in a room.  Why do we feel colder when we touch the metal spoon than when we touch the wooden one? a. Since metals usually have a lower heat capacity than non-metals, the metal spoon loose more heat to the room and consequently has a lower temperature b. Metals release heat faster than non-metals because of their higher thermal conductivity c. This is merely psychological since we are conditioned to think of metals as “cold” d. Metals absorb heat faster than non-metals because of their higher thermal conductivity

Working with machines that have cutting wheels, lifting heavy objects with cranes, and working with high voltage electrical circuits are examples of dangerous jobs. Select one: True False

Chapter 6 discussed the Laws of Thermodynamics and their relation to energy and energy transfer. Energy transfers take place constantly in everyday activities. Think of two scenarios: cooking on a stove and driving. Explain how the second law of thermodynamics applies to these two scenarios. Using thermodynamic theory as a foundation, devise and comment on what you consider to be a good rationale for responsible consumerism.

Which of the following will have a higher rate of heat transfer. With conduction heat transfer.    A. pulverized shale stone  B. the stone and the pulverized shale will have the same heat transfer as they have the same conductivity constant.  C. a solid block of shale stone  D. the pulverized shale will have a higher heat transfer as it has a higher duction coefficient

What would be the likely steps needed to be taken to plan the research, funding, and installation of Hydrogen car Chargers in a big city?

Energy savings methodology can save energy. Suggest three ways related to energy savings that you can implement to encourage people around you to save energy together with you. Provide explanations of how the three methods will contribute to saving energy.

how you as a future professional engineer can exemplify this virtue; temperance and purity?

True or False High-tech research in Singapore includes the elusive but all-consuming invention that drove Nicola Tesla - Wireless Power Transfer.
