What are the factors that affect the kinetic energy of the vehicle? 1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy. Does height affect energy? Since the gravitational potential […]
What does temperature of inversion depend on?
What does temperature of inversion depend on? This temperature depends on the temperature of the cold junction and the nature of the material. What is thermo emf? A thermo EMF(E) arises when two metal junctions are maintained at different temperatures. Thermo emf is developed by keeping one juction at 0∘C and varies with temperature and […]
How does science affect the society?
How does science affect the society? Science influences society through its knowledge and world view. Scientific knowledge and the procedures used by scientists influence the way many individuals in society think about themselves, others, and the environment. How did society shape science and science shape society? Science shaped the society through technological advancement and growth […]
What are the types of dimensional tolerance?
What are the types of dimensional tolerance? Types of Geometric Tolerances Form Tolerance (Form Deviation) Form Tolerance and Location Tolerance (Profile Tolerance of Line / Profile Tolerance of Plane) Orientation Tolerance. Location Tolerance (Location Deviation) Run-out Tolerance (Run-out Deviation) Maximum Material Condition (MMC) and Least Material Condition (LMC) What is a zero basic dimension? Implied […]
What is the output of current sensor?
What is the output of current sensor? Current Sensor detects the current in a wire or conductor and generates a signal proportional to the detected current either in the form of analog voltage or digital output. Current Sensing is done in two ways – Direct sensing and Indirect Sensing. Can I take off the third […]
Does an experiment need a control group?
Does an experiment need a control group? An experiment may include multiple experimental groups at one time. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results. While all experiments have an experimental group, not all experiments require a control group. […]
How can you determine the direction of field lines?
How can you determine the direction of field lines? A magnetic field line is the path along which a free north-pole tends to move. The direction of a magnetic field at a point is determined by placing a small compass needle. The N – pole of compass indicates the direction of magnetic field at that […]
How do you measure a caliper diameter?
What is the best temperature scale?
What is the best temperature scale? This is one reason Fahrenheit is superior The ambient temperature on most of the inhabited world ranges from -20 degrees Fahrenheit to 110 degrees Fahrenheit — a 130-degree range. On the Celsius scale, that range is from -28.8 degrees to 43.3 degrees — a 72.1-degree range. How do you […]
Why digital signals are better than analog?
Why digital signals are better than analog? The configuring process of digital signals is easier than analog signals. Digital signals can be saved and retrieved more conveniently than analog signals. Many of the digital circuits have almost common encoding techniques and hence similar devices can be used for a number of purposes. Is the human […]
