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 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 […]
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 […]
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 […]
How long does it take for the moon to move a distance equal to its own diameter?
What killed Fidel Castro?

Four sitting presidents have been killed: Abraham Lincoln (1865), James A. Garfield (1881), William McKinley (1901), and John F. Kennedy (1963). Additionally, two presidents […]
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 balance a pendulum clock?
What is the relationship between height and pressure?
What is the relationship between height and pressure? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a […]
