Answer:
That is false, Protons have a positive charge, Electrons have a negative charge, and Neutrons have a blank charge.
Explanation:
Answer:
The total charge Q of the sphere is .
Explanation:
Given that,
Radius = 5 cm
Charge density
We need to calculate the total charge Q of the sphere
Using formula of charge
Where, = charge density
V = volume
Put the value into the formula
Put the value into the formula
Hence, The total charge Q of the sphere is .
The answer is A. Plant growth, Plant growth is the only thing that can actually be tested and scientificly measured, hope this helps!!!!
Answer:
I'm not completely sure, but I believe the first and third of the three are mechanical.
Explanation:
Chemical potential isn't moving or about to go into motion. It can't be mechanical.
Explanation:
It is given that,
A planet were discovered between the sun and Mercury, with a circular orbit of radius equal to 2/3 of the average orbit radius of Mercury.
Mass of the Sun,
Radius of Mercury's orbit,
Radius of discovered planet,
Let T is the orbital period of such a planet. Using Kepler's third law of planetary motion as :
T = 4135214.625 s
or
T = 47.86 days
So, the orbital period of such a planet is 47.86 days. Hence, this is the required solution.
