Answer: Only 2 and 3
Explanation:
2.) Wavelength has an inverse relationship with wave frequency when wave speed remains constant.
3.) Wave speed is directly related to the product of wavelength and frequency.
V = F(λ)
Where
V = wave speed
F = wave frequency
(λ) = wavelength.
True. The amount of water on Earth is consistent even if it is displayed in different forms.
The period of the planet is 58.1 years
Explanation:
We can solve this problem by using Kepler's third law, which states that:
"The square of the orbital period of a planet is proportional to the cube of its semimajor orbital axis"
Translated into equations, we can write:
Where, taking the orbits of the planets as almost circular, we have:
is the orbital period of the unknown planet
is the radius of the orbit of the planet
(1 year) is the period of the orbit of the Earth
is the orbital radius of the Earth
Solving for , we find the orbital period of the unknown planet:

Answer:
2 atoms of oxygen in carbon dioxide
Explanation:
Answer:
Work is equal to the change in kinetic energy.
Explanation:
The law relating work and kinetic energy states that "the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle."
This theorem is also called the work energy principle.
It was derived from the law of conservation of energy.
This principle stands even if there is a single force acting on the body. The change in the kinetic energy of the body is equal to the work done.
Mathematically,
W = ΔK.E.
