What is the difference between dysphasia and aphasia? Aphasia is the medical term for full loss of language, while dysphasia stands for partial loss of language. The word aphasia is now commonly used to describe both conditions. Can dysphasia be cured? In mild cases of dysphasia, language skills may be recovered without treatment. However, most […]
Is calcium smaller than magnesium?
Is calcium smaller than magnesium? However, a magnesium ion has a smaller radius than a calcium ion. This means that a magnesium ion polarises a carbonate ion more than a calcium ion does. Therefore, magnesium carbonate is easier to decompose than calcium carbonate and does so at a lower temperature. Why is magnesium ion smaller […]
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 […]
Is it possible to see radio waves?
Is it possible to see radio waves? The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes. Why do pulsars spin so fast? […]
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 the hottest country in the world?
What is the hottest country in the world? Djibouti How hot is 40 degrees in Australia? In Central Australia, we find extreme temperatures sometimes it may reach up to 50 degrees and cannot see rains for years….Air Temperature. Degree Centigrade Degree Fahrenheit 31 88 35 95 38 100 40 105 Is Australia the hottest place […]
What is the meaning of angle of incidence and angle of reflection?
What is the meaning of angle of incidence and angle of reflection? At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the […]
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. […]
Why gravitation is always attractive?
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 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 […]
