Answer:
Explanation:
- The expression for acceleration of the rolling body on an inclined plane is given as a = gsinФ/1 + k²/R²
- where Ф is the angle of inclination, R is the radius, k is the radius of gyration.
- The potential energy of the system is given as ; PE = mgh
- The potential energy will be constant for ring, cylinder, solid sphere, and hollow sphere.
- The total kinetic energy of the rolling body is ; KE = mv²/2 + Iw²/2
- Hence, the total kinetic energy of the ring, cylinder, solid sphere and hollow sphere will be constant.
2. The moment of inertia of the ring is given as ;
I = mR²
The moment of inertia of the ring is maximum and therefore reaches the bottom last.
Answer:
An estuary is the area where a river meets the sea or ocean, where fresh water from the river meets salt water from the sea.
A train is a very big and heavy object, so the bigger the object is, the slower it will begin to move. With that said, bigger objects are also heavier and will move fast once going. Since the train is a huge and heavy object it will need longer time to slow down and come to a stop.
