The variable period of a moon of Jupiter, which is the basis of measurement of the speed of light in Roemer's method (whoever heis), is regarded as the Doppler affect. The period of the orbital motion of one of Jupiter's moons is approximately42.5hours; the speed of light is 2.99e8 m/s. The orbital speed of the Earth about the Sun is 2.98e4 m/s. What is the maximum change in the period (in seconds) of this moons observed from Earth? (hint: T = 1/f) I've done Doppler problems with two moving objects but I cant come up with an answer that makes sense. How do i use frequency to solve this? (thanks the other"kp")
Will there be any change in hz of sound if two vibrating body has the similar hz Ans) Yes it depends on the path difference among them... Like in destructive inteference u
Force: Force may be defined as a push or a pull upon an object. In the English system the pound (1b) is used to express the value of a force. For example, we say that a force
