Hey
The rock is in fluid state!!!
Can u give me a brainliest answer???
The specific gravity is the ratio of the substances density to that of water at 4 degrees Celsius. With this, it is conclusive that the density of iron is 7.87 g/cm³. The volume occupied by the iron is the quotient when mass is divided by density,
V = m / D = (7 g) / (7.87 g/cm³) = 0.89 cm³
Therefore, 7 grams of iron occupies approximately 0.89 cm³.
It will stay in motion unless an outside force slows it down.

Question: : A similarity between electromagnetic waves and matter waves?
----------------------------------------------------------------------------------------------------------------
Answer: electromagnetic waves are the combination of electric field and magnetic field and the matter wave related to dicrete particles. They are both waves (obviously), and both are made of particles which obey the equation E = hf. Where E is the energy of a particle and f is its frequency. Matter waves can move at varying speeds, and matter waves can be at rest. EM waves always move at c in vacuum.
