An ultrasound signal of frequency 50 KHz is sent vertically down into a medium. The signal gets reflected from a depth of 25 mm and returns to source 0.00005 seconds after it is emitted. The wavelength of the ultrasound signal in that medium is ............... cm.
The relationship between the applied force \( F(X) \) (in Newton) on a body and its displacement \( X \) (in metre) is given below. The total amount of work done in moving the body from \( X = 0 \) to \( X = 4 \, \text{m} \) is ............ Joule.
Use the diagram below to answer the following questions. 40 spheres of equal mass make two rings of 20 spheres each. The ring on the right has a radius twice as large as the ring on the left.
At what position could a mass be placed so that the net gravitational force that it would experience would be zero?
