in a reference frame s, the volume of a cube is 1000cc.find the volume of the cube in a reference s'.which is moving paralell to the edge of the cube with a velocity 80%of that of light

**physics**

two inertial frame s and s' have their axes paralell and pasitions of origin o' of s' relative to origin to s is given by ro=i+j+3k.what is the magnitude of position vector of a point p in s' if the co-ordinates p in s is(2,3,4)

find the effective weight of an astronuat ordinarily weighing 50kg when his rocket moves vertically upwards with 6gm acceleration

**physics**

in michelson-morley experiment the wavelength of the monochromatic light used is 5000A.calculate the expected fringe shift on the basis of stationary ether hypothesis if the effective length of each path is 5m.given c=3*10^8m/s

**physics**

position of a particle in frame s is given by r=(6t^2-4t)i-3t^3j+3k.in another frame s',its position of the same particle is given by r'=(6t^2+2t)i-(3t^3+8t)j+3k.what is the magnitude of relative velocity of s' with respect to s if r and r'are measured in metre...
