On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.
Answer:
Its rotation will be 3.89x10⁴ rad/s.
Explanation:
We can find the rotation speed by conservation of the angular momentum:
(1)
The initial angular speed is:
The moment of inertia (I) of a sphere is:
(2)
Where m is 9 times the sun's mass and r is the sun's radius
By entering equation (2) into (1) we have:
Hence, its rotation will be 3.89x10⁴ rad/s.

Answer:
The path of an object in uniform motion is a straight line.
Answer:
This was done by measuring the acceleration due to gravity as accurately as possible and then calculating the mass of Earth M from the relationship Newton's universal law of gravitation gives mg=GmMr2 m g = G m M r 2 , where m is the mass of the object, M is the mass of Earth, and r is the distance .
