Two objects have mass 8 kg 25 kg which one has more inertia why |
|
Answer» Answer: Answer: Inertia is DIRECTLY proportional to the mass of the object. So if the mass of an object is more then it's inertia will be more else less. So from 8kg and 25KG, obviously 25kg is HEAVIER so the inertia of the 25kg object is more |

CHAPTER_6) WHAT IS GRAVITATION |
|
Answer» Gravity, ALSO called gravitation, in mechanics, the universal force of attraction ACTING between all matter. ... On Earth all bodies have a weight, or downward force of gravity, PROPORTIONAL to their mass, which Earth's mass exerts on them. Gravity is MEASURED by the acceleration that it gives to freely falling objects. |

Prove quantum theory of gravity. Is it possible? If not then why? |
|
Answer» Answer : ONE of the difficulties of formulating a quantum gravity theory is that quantum gravitational effects only appear at length scales near the Planck scale, around 10−35 meters, a scale far smaller, and hence only accessible with far HIGHER energies, than those currently available in HIGH energy particle accelerators.

Water droplets, of mass m each, are dripping from height h at a rate of r per second. Find the center of mass of the droplets.The position of each droplet is a function of time. The number of drops is also a function of time. If possible, express the final answer as an integral in time. |
|
Answer» centre of mass will lie at the centre of sphere i.e. the point where each and EVERY symmetrical AXIS of sphere intersects with other axis.. position of each droplet as a function of time will be given as position = H - (gt^2)/2 g= accn due to gravity H = initial height t = time in seconds please mark it as brainliest if uh got help.. |
