Vector Addition
While we become students of physics and approach the job of adding vector quantities, we soon become aware of the fact in which the addition of two vector quantities along with magnitudes of 6 and 8 will not necessarily result in an answer of 14. The rules for adding vector quantities are various than the rules for adding two quantities arithmetically. Therefore, vectors along with magnitudes of 6 + 8 will not unavoidably sum to 14.
An undersea explosion occurs. If the sea water has density 1.03 x 10 3 kg/m3 and Bulk Modulus of 2.41x10 9 Nm -2 ; a) Determine the velocity of sound in sea water b) If
Power: The rate of doing work is called power, and it is defined as the work done in unit time. As a formula, this would be: power = work done/time Taken Power is exp
Gravitational field can also be shown by lines of force. This is same in several ways as that of electric lines of forces. With one dissimilarity, electric charges are negative and
Resistance measurements: An example of how to make AC voltage measurements is shown in the diagram below. Once again, the red and black test leads are connected to the '+' and
A convex lens of refractive index 1.5 of focal length 0.2m is immersed in water of refractive index 1.33. Determine the focal length of lens in water.
Electric field (intensity) is a vector number. Electric field because of a positive particle is always away from the charge and that because of a negative charge is always toward
