Answer:
Explanation:
Between two spheres of equal masses having equal radius , the one which is hollow will have less moment of inertia and therefore less radius of gyration ( k )
When they are allowed to roll over an inclined plane , they will have acceleration as follows
a = gsinθ / ( 1 + k²/r²)
For hollow sphere , k is less . therefore denominator is less and acceleration is more.
in other words , hollow sphere will have greater acceleration . So it will reach the bottom of an inclined surface in lesser time if allowed to roll over it .
This is how we can identify a hollow sphere without breaking it open .
yes, because you have to observe your experiment while doing it in case something goes wrong
In chemistry, a valence electron is an outer shell electron that is associated with an atom and that can participate in the formation of a chemical bond only the outer shell is not closed. So, the answer to this question wold be outermost energy level.
Ans: Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object. The classic example of potential energy is to pick up a brick.
