Green has a shorter wavelength.
It is very easy..let me tell you.. there are seven colors in the rainbow. Isn't it?
According to their decreasing order of wavelength , they are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet.
It is as simple as that to remember....
Answer:
Transduction.
Explanation:
Transduction is actually a process which involves the conversion of energies or messages from one kind to another. So in this case the transfer of light energy received by the eyes into the message for the brain is also called as transduction.
Answer:
A simple machine having a velocity ratio of 3 simply means that the ratio of the distance moved by effort to the distance moved by load is equal to 3.
Explanation:
A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.
Basically, a simple machine allows for the transformation of energy into work. The six simple machines are;
I. Inclined plane.
II. Screw.
III. Wheel and axle.
IV. Lever.
V. Wedge.
VI. Pulley.
Mathematically, the velocity ratio of a simple machine is given by the formula;
Hence, a simple machine having a velocity ratio of 3 simply means that the ratio of the distance moved by effort to the distance moved by load is equal to 3.
Answer:
c. the speed of a planet is greatest when it is closest to the Sun.
Explanation:
Johannes Kepler was an astronomer who discovered that planets had elliptical orbits in the early 1600s (between 1609 and 1619).
The three (3) laws published by Kepler include;
I. The first law of planetary motion by Kepler states that, all the planets move in elliptical orbits around the Sun at a focus.
II. According to Kepler's second law of planetary motion, the speed of a planet is greatest when it is closest to the Sun.
Thus, the nearer (closer) a planet is to the Sun, the stronger would be the gravitational pull of the sun on the planet and consequently, the faster is the speed of the planet in terms motion.
III. The square of any planetary body's orbital period (P) is directly proportional to the cube of its orbit's semi-major axis.
