Answer:
The weight of the body in the new planet is 100 newtons.
Explanation:
From Newton's Law of Gravitation we find that gravitational force is directly proportional to mass of the planet and inversely proportional to the square of its radius. From this fact we can build the following relationship:
(1)
Where:
, - Gravitational force, measured in newtons.
, - Mass of planet, measured in kilograms.
, - Radius of the planet, measured in meters.
If we know that , and , then the expected gravitational force in the new planet is:
The weight of the body in the new planet is 100 newtons.
Radial acceleration is = v^2/r
Therefore (8.8m/s)^2/(25m)= 3.10m/s^2
Hope this helps you! Any questions please just ask! Thank you!
Gentian violet is an antiseptic dye that has been in use since 1890. The name is due to its colour — it is not made from gentian or violet flowers.

Parent have great influence on their child's mindset and there are several instances where parent's thinking determine what their child become in near future. For example, during toddler-hood babies learn to walk and talk and with time development of language take place which is largely determined by the behavior, thinking and feeling of parent.
