Why gravitation is always attractive? In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces. […]
What is the difference between subduction zones and hot spots?
What is the difference between subduction zones and hot spots? Subduction zones are areas in which oceanic plates are overridden by continental plates, forcing the heavier oceanic crust deep enough to be melted and recycled as second generation magma. Hot spots provide information about the rates and directions of movement of tectonic plates over geologic […]
What is the relation between frequency and wavenumber?
What is the relation between frequency and wavenumber? Frequency is a measurement of the number of wave cycles per second. Wavenumber is the reciprocal of the wavelength multiplied by a constant. Although they look the same, the difference is that wavenumber has nothing to do with the velocity of the wave- wavenumber is measured in […]
What is the ultimate original source of energy?
What type of energy is present in the batteries of a flashlight 5 points?
What type of energy is present in the batteries of a flashlight 5 points? Electrical energy What type of energy is it when the light switch is in the off positions? With electrical energy, it’s helpful to think of an on/off switch. When the switch is off, the electrical energy is stored as potential energy. […]
How do you analyze graphical data?
How do you analyze graphical data? Data Analysis & Graphs Review your data. Try to look at the results of your experiment with a critical eye. Calculate an average for the different trials of your experiment, if appropriate. Make sure to clearly label all tables and graphs. Place your independent variable on the x-axis of […]
What is the downside of having a smart meter?
What is the downside of having a smart meter? Although smart meters can help you keep track of your energy use, they could also drive up anxiety with elderly or low-income households if they’re constantly reminded of what they’re spending. This could lead to people depriving themselves of adequate heating or lights. How does a […]
What is currently the most popular trait theory of personality?
What is currently the most popular trait theory of personality? Trait theorists attempt to explain our personality by identifying our stable characteristics and ways of behaving. The Five Factor Model is the most widely accepted trait theory today. The five factors are openness, conscientiousness, extroversion, agreeableness, and neuroticism. These traits occur along a continuum. Is […]

What is two-way radio communication in aviation? Two-way radios are used by groups of geographically separated people who need to keep […]
What happens if we use white light instead of laser?
What happens if we use white light instead of laser? Answer White light consists of waves of innumerable wavelengths ranging from violet to red color. So if monochromatic light in Young’s double-slit experiment is replaced by white light, then the waves of every wavelength form their separate interference patterns. Which type of light source is […]
