A pendulum bob when released from position X, hits a plastic cup on ground and toppled it to its side.
Which one of the following correctly shows the conversions of energy that took place in this experiment?
A Potential energy of pendulum bob → Kinetic energy of pendulum bob → Potential energy of plastic cup → Sound energy
B Potential energy of pendulum bob → Kinetic energy of pendulum bob → Kinetic energy of plastic cup → Sound energy
C Kinetic energy of pendulum bob → Potential energy of plastic cup → Sound energy
D Kinetic energy of pendulum bob → Potential energy of pendulum bob → Kinetic energy of plastic cup → Sound energy

Abhinav studied about the plants found in a region.
Following is an excerpt from the paragraph:
The stem are great at storing water. With their waxy coating, water can't escape and spines protect them from being food of animals. Their roots are shallow, and widely spread. They grow in a soil that can absorbs any rain.
Which region's plants did Abhinav study?
