CBSE XI Science Physics Oscillations
Dear Topper
These questions are actually a general question which come under practical section and are not exactly from this chapter.The questions are:
1.When an ice cube is kept in the place of a bob in a simple pendulum , what change will happen to the pendulum?Will the length of the pendulum increase or decrease?
2.When a simple pendulum is kept on the moon , what is the difference seen on its speed of oscillation and time period?
3.What type of spring is usedin a shock absorber?Will a rigid spring or a flexible spring have more spring constant?
Please do give me the answers as soon as possible
