Answer:
The measured value of the constant is known with some certainty to four significant digits. In SI units, its value is approximately 6.674×10−11 m3⋅kg−1⋅s−2. The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys.
It is vital to take measurements at the same time everyday to determine the natural cycle, this will show the numbers on a regular basis. It is important because this will be basis of any action that needs to be taken. If it's not taken at the same time, it may disrupt the correct result or change the expected outcome.
The charge would be in equilibrium so there would be no charge in the body of the conductor.
Answer:
(b) there cannot be any charge in the body of the conductor
Speed of light is given as

time interval is given as

so the distance covered by the light is given as


now as we know that

so the distance moved by light is

now for the comparision of this distance with diameter of earth
as we know that radius of earth is

so the diameter of earth will be

now the ratio of diameter with the distance that light move will be


<em>so it is 2.35 times more than the diameter of earth</em>
Answer:
8.97 days
Explanation:
Assuming we are asked what will be the period of revolution, this planet's year, in Earth days?
The period of revolution T is given as

here, r= distance between planet and its sun which is same as distance between Earth-Sun = 
g= acceleration due to gravity = 
therefore,

=775580 seconds
= 8.97 days
