The correct answer is C. Universal Gravitation (it was written by Issac Newton)
It would be rock by erosion bc the rocks erode to form a volcano
Answer:
5501 kg/m^3
Explanation:
The value of g at the Earth's surface is

where G is the gravitational constant
M is the Earth's mass
is the Earth's radius
Solving the formula for M, we find the value of the Earth's mass:

The Earth's volume is (approximating the Earth to a perfect sphere)

So, the average density of the Earth is

Answer:
Explanation:
a )
The Gaussian surface must have contained both the charges like +3 nC and - 3 nC , total charges being zero . According the Gauss's law , total electric flux over a closed surface is equal to 1 / ε₀ times the total charge contained inside the closed surface .
Since total charge inside is zero , total flux will be 1 / ε₀ x 0 = 0
b )
In this case the Gaussian surface is so small that it contains only the charge
+ 3 nC .
So electric flux over the Gaussian surface
= ( 1 / ε₀ ) x 3 x 10⁻⁹
= (1 / 8.85 x 10⁻¹² ) x 3 x 10⁻⁹
= 3 x 10³ / 8.85
= 339 weber.
=
Answer:
D. (static equilibrium)
