What is the angle of reflection if the angle of incidence is 30 degree? Explanation: The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 – 30 = 60 degrees. What […]
How do you calculate perihelion?
How do you calculate perihelion? The perihelion distance P=a(1−e) and the aphelion distance A=a(1+e) where e=0.875 is the eccentricity. This gives a perihelion distance of 2.375AU and an aphelion distance of 35.625AU. How is Pericenter calculated? The angle from the ascending node to the pericenter, measured in the plane of the orbit….The eccentricity of an […]
What is Gauss law for electric flux?
What is Gauss law for electric flux? Gauss’s law states that: The net outward normal electric flux through any closed surface is proportional to the total electric charge enclosed within that closed surface. How do you fix electric flux problems? Solution: To compute electric flux, we need the magnitude of the electric field, area of […]

Is water a molecule or compound?
Is water a molecule or compound? Water is a compound. It contains more than one element: hydrogen and oxygen atoms are joined together; as illustrated in the video clip Elements and Compounds, above. An important feature of compounds is that they are very different from the elements from which they are made. Which is not […]
What does baking soda do to cabbage?
What does baking soda do to cabbage? The baking soda, by the way, may make overcooked cabbage smell less objectionable and maintain the green color long after it should have turned grayish from the long cooking, but it also robs the cabbage of its vitamins. When you add vinegar to baking soda what happens? When […]

What is difference between hypothesis and prediction?
What is difference between hypothesis and prediction? Difference Between a Hypothesis and Prediction Hypothesis and prediction are both a type of guess. However, the hypothesis is an educated, testable guess in science. A prediction uses observable phenomena to make a future projection. What is the relationship between Type 1 and Type 2 error? In statistical […]
What is the basic requirements of hydroelectric power station MCQS?
What is the basic requirements of hydroelectric power station MCQS? Availability of water, large catchment area and rocky land are primary requirements for site selection of hydroelectric power plant. Explanation: Potential energy of large quantity of stored water is used by hydroelectric power plant to generate electrical energy. What is the gross head of hydroelectric […]
