A rectangular track is 40m long and 30m broad a man starts walking from one corner of the track and reaches the opposite corner find the distance travelled and the magnitude of displacement?
The distance traveled by the man is equal to the perimeter of the rectangle which is 40m + 30m + 40m + 30m = 140m. The magnitude of displacement is the shortest distance between the initial and final positions, which is the diagonal of the rectangle. Using the Pythagorean theorem, the diagonal is √(40^2 + 30^2) = √(1600 + 900) = √2500 = 50m.
If you are walking at 2 ms for a distance of 40m how long does it take you?
It would take you 20 seconds to walk 40m at a speed of 2 m/s. (Distance/Speed = Time)
If your face is 20cm in front of a mirror what is the image of your face?
The image of your face will appear to be 20cm behind the mirror, making the total distance between your face and its image 40cm. The image will be laterally inverted compared to your actual face.
What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the equation for calculating the phase difference between two waves?
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
