Do you really need anti-static wrist strap? It is not vitally important to either your safety, or the safety of your computer’s electrical components that you use an anti-static strap / mat. That being said, it does not hurt anything at all to be using one, and it will definitely help to ensure that everything […]
Does the Firefly 2 plus get you high?
In which case magnification is less than 1?
In which case magnification is less than 1? In a concave mirror, when the distance of the object is less than the focal length, the magnification will be greater than one. When the distance of the object is greater than the focal length, then the magnification is less than one. Can the magnification be less […]
How do you know if something is moving at constant velocity?
How do you know if something is moving at constant velocity? Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its […]
What are the two formulas for refractive index?
What are the two formulas for refractive index? Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v. What is the relation between refractive index and thickness? Thus there is no general relation between refractive […]
What are the different charge distributions?
What are the different charge distributions? There are three types of charge distributions : a) Linear Charge Distribution. In this distribution the charge is distributed uniformly along a line in a straight line or circumference of a circle. c) Volume Charge Distribution. What is the meaning of charge distribution? A charge distribution is ultimately composed […]
Why does the CMB appear so uniform in all directions?
Why does the CMB appear so uniform in all directions? The problem is that, when we look up at the sky, and take a look at the microwave radiation (that’s the leftover radiation from the big bang), we find that it’s the same temperature, 2.725 Kelvin, in every direction. The motion of us against the […]
Which is true of the scientific method?
Which is true of the scientific method? Explanation: The scientific method can be described as the basic procedure through which all scientific researches are organized and it determines the accuracy of all scientific theories and researches. Hence, option A is correct. The scientific method starts with a question based on which a hypothesis is derived. […]
How much light goes through a polarizer?
How much light goes through a polarizer? At the end of Example 1, it was stated that the intensity of polarized light is reduced to 90.0% of its original value by passing through a polarizing filter with its axis at an angle of 18.4º to the direction of polarization. What is the intensity of the […]
What is the importance of unit?
What is the importance of unit? Chemists measure the properties of matter and express these measurements as quantities. A quantity is an amount of something and consists of a number and a unit. The number indicates how many (or how much), and the unit describes the scale of measurement. How do I get better at […]
