Answer:
The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Explanation:
Answer:
The correct answer is option 'a' 'The momentum is always conserved while as the kinetic energy may be conserved'
Explanation:
The conservation of momentum is a basic principle in nature which is always valid in an collision between 'n' number of objects if there are no external forces on the system. It is valid for both the cases weather the collision is head on or glancing or weather the object is elastic or inelastic.
The energy is only conserved in a collision that occurs on a friction less surface and the objects are purely elastic. Since in the given question it is mentioned that only the surface is friction less and no information is provided regarding the nature of the objects weather they are elastic or not hence we cannot conclusively come to any conclusion regarding the conservation of kinetic energy as the objects may be inelastic.
Answer:
The speed of sound in a rod made of the material is 3215.52 m/s.
Explanation:
The speed of sound can be found using the formula:
Where s is the stiffness, m the atomic mass and d is the length of the interatomic bond.
You just have to correctly replace these values in the formula above.

V= 3215.52 m/s
Answer:
2. Binary fission frequency differs between species and is affected by environmental conditions
4. Binary fission results in offspring, which are genetically identical to the parent cell.
Explanation:
Binary fission is the process of asexual reproduction of single-celled organisms that consists of dividing a cell into two by mitosis, each with the same genome as the "mother cell" (with the same DNA or genetic material as the "mother cell" ).
The binary fission process is directly affected by genetics, that is, it varies from species to species. In addition, binary fission occurs depending on specific environmental conditions (such as water, optimal temperatures and also pH).
