Answer:d
Explanation:
Given
Initially, the ice cube is floating over the water
When the cube is pressed to touch the bottom, it is submerged fully
Therefore more buoyant force is acting on it
At first, a part of the volume is submerged in the water, so the buoyant force is less, but as the entire cube is immersed in the water, the buoyant force increases.
You will see some thing pitch black pulling you. you will feel an immense pull or attraction while going rapidly inside the black hole.
Answer
A
Explanation:
Weight = Mass x Acceleration due to gravity
Weight = 1000 x 9.81
= 9810 or 9.81x10^ 3
Answer:
Option B. quantum mechanics
Explanation:
Quantum Mechanics, at atomic and sub-atomic levels deal with the study of how particles at this level behave and how the matter and energy interacts.
It also explains the properties of atoms, molecules and the particles constituting these.
The wave- particle duality of quantum mechanics that says that matter or every quantum of it exhibits wave as well as particle nature.
This theory was incorporated with its mathematical description given by Schrodinger was also incorporated in the theory for eave-particle duality and The probability for the existence of particle was determined.
