Answer: 88 Earth days
Explanation:
According to the Kepler Third Law of Planetary motion <em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.
</em>
<em />
In other words, this law states a relation between the orbital period 
of a body (moon, planet, satellite) orbiting a greater body in space with the size 
of its orbit:
(1)
If we assume the orbit is circular and apply Newton's law of motion and the Universal Law of Gravity we have:
(2)
Where 
is the mass of the massive object and 
is the universal gravitation constant. If we assume constant and larger enough to consider really small, we can write a general form of this law:
(3)
Where is in units of Earth years, is in AU (<u>1 Astronomical Unit is the average distane between the Earth and the Sun)</u> and is the mass of the central object in units of the mass of the Sun.
This means when we are making calculations with planets in our solar system 
.
Hnece, in the case of Mercury:
(4)
Isolating :
(5)
(6)
This means the period of Mercury is 88 days.
Answer:
water
Explanation:
water is not an element, it is a molecule
Answer:
A stormy ocean, having the most kinetic energy means it moves more and faster
Answer:
Son aquellas ondas que no necesitan un medio material para propagarse. Incluyen, entre otras, la luz visible y las ondas de radio, televisión y telefonía. Todas se propagan en el vacío a una velocidad constante, muy alta (300 0000 km/s) pero no infinita.
Option C,
Reason
Kinetic energy is proportional to the square of velocity. Thus the higher the velocity the higher will be the kinetic energy
K.E. dog = 1/2 x 10 x (0.44704 x 30)^2 m/s = 899.14 J
K.E. bullet = 1/2 x 0.02 x (0.44704 x 8000)^2 m/s = 127,878 J
