Distance from the sun.
<span>The third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit</span>. The semi-major axis is the distance from the sun to the epicenter of the ellipse (which would be the planet in question). So, the revolutionary period is directly related to the distance of the planet from the sun.
Answer:
0.02
Explanation:
Force,
where N is normal reaction and coefficient of kinetic friction is
. Also, N is equivalent to mg ie N=mg where m is mass of an object and g is acceleration due to gravity. Making
the subject of the formula then

Substituting F with 2 N, m with 10 kg and g with 9.81 then

Answer:
The density of iceberg upper water and under water are 102.5 kg/m³ and 922.5 kg/m³
Explanation:
Given that,
Volume of seawater = 90 % of Volume of iceberg
Volume of visible surface = 10 %
Density of seawater = 1025 kg/m³
We need to calculate the density of the iceberg
Using equilibrium condition


Put the value into the formula
