Describe how wavelength, frequency, and energy are related.
Answers
The wavelength and frequencyincrease (decrease) in proportion to energy levels. Short wavelengths have a higher energy than long wavelengths because of the link between wavelength and frequency, which dictates that the higher the frequency, the shorter the wavelength.
What is energy?
Energy is defined as the capacity of a physical system to perform work.
Wavelength is related to energy and frequency by
E = hν = hc/λ,
where E = energy, h = Planck's constant, ν = frequency, c = the speed of light, and λ = wavelength
The number of waves that pass a specific place in a predetermined period of time is known as the wave frequency. The hertz is the wave frequency SI unit (Hz)
The distance between two successive crests or troughs of a wave is known as its wavelength. It is calculated using the wave's direction.

All the statements regarding law of conservation of energy are true except for statement 2 stating energy changes half way down the ramp.
What is law of conservation of energy?
According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.Energy of an isolated and closed system remains constant.

What is the force of gravity on the rocket at the planet's surface?
What is the force of gravity on the rocket at a distance of two units (twice the planet's radius from its center)?
In general, how does the force of gravity pulling on the rocket change as the distance between it and the planet increases?
Answers
-- The relationship between the distance from the planet's center and the force of gravity on the ship has been graphed. That's the reason for the labels on the axes.
-- The distance from the planet's center is labeled in multiples of the planet's radius.
The force of gravity on the ship is labeled in multiples of 1 million newtons.
-- The force of gravity on the rocket at the planet's surface (1 radius from the center) is 4 million newtons. (about 899,203 pounds)
-- The force of gravity on the rocket at a distance of two units (twice the planet's radius from its center) is 1 million newtons.
-- In general, as the distance between the rocket and the planet increases, the force of gravity pulling on the rocket decreases.
From our studies of the nature of gravity, we know that the force is inversely proportional to the square of the distance between the center of the rocket and the center of the planet. We might not notice it from the graph, because there's only one labeled point that clearly shows it. (2radius, 1/4 of the surface force).
If we have been really attentive to our studies and have done all of our gravity homework, we know that the equation of the purple line on the graph is
Force = (4 million newtons) / (Distance)² for Distance >= 1 radius.

Voltage difference causes charge to flow from higher potential to that of a lower potential.
What is Potential difference?
This is also known as Voltage difference and it is the difference in electric potential between two points.
V= W/Q
where v is potential difference, w is work done and q is charges.
This allows for charges to flow from higher potential to that of a lower potential.

Answer:
Voltage difference causes charge to flow from higher potential to that of a lower potential.
Explanation:
Voltage Difference:
It is work done per unit charge in moving a charge from one point to another point.
V = Voltage difference
W = Work done
Q = Charge
Then,
unit : Volt or Joule/Coulomb
Flow of charge :
A free positive charge move from a region of higher potential to that of lower potential whereas a free negative charge moves from lower potential region to a higher potential.
Thus, a voltage difference is required for the flow of charge.
Direction of conventional current is from positive terminal to negative terminal.
Direction of electron is from negative to positive.
