Answer:
3,4,1 and 6,5,2
Explanation:
In the electromagnetic spectrum the arrangement of the waves in increasing frequencies and decreasing wavelengths are as follows;
Radio waves
Microwaves
Infrared waves
Visible light rays
Ultraviolet rays
X-rays
Gamma rays
(a simple mnemonic is RMIVUXG)
The correct option is B.
Carbon is an element with an atomic number of 6. Each atom of carbon is made up of electron, proton and neutron. Carbon has six protons and six neutrons in its atom but its number of neutrons differ. This is because carbon exhibit isotopy. The isotopes of carbon are: carbon 12, carbon 13 and carbon 14. Carbon 12 has 6 neutrons, carbon 13 has 7 neutrons and carbon 14 has 8 neutrons.
We can characterize properties of a substance to identify it because it helps us determine how the substance should be used. We can identify a substance by using physical or chemical properties. These help us by telling us which chemical we are looking at.
I hope this helps.. I wasn't sure what kind of answer you were looking for.
Explanation:
Speed depends on your referential. Some chemical reactions can take only a fraction of a second while others take days.
Combustion is typically very fast. You can also try and look at lithium+water which is a dangerous, fast and exothermic reaction.
Answer:
Axis
Anatomy
In anatomy, the second cervical vertebra of the spine is named the axis or epistropheus. By the atlanto-axial joint, it forms the pivot upon which the first cervical vertebra, which carries the head, rotates.
Rotation
A rotation is a circular movement of an object around a center of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axis. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin.
Revolution
In political science, a revolution is a fundamental and relatively sudden change in political power and political organization which occurs when the population revolts against the government, typically due to perceived oppression or political incompetence.
Elliptic orbit
In astrodynamics or celestial mechanics, an elliptic orbit or elliptical orbit is a Kepler orbit with an eccentricity of less than 1; this includes the special case of a circular orbit, with eccentricity equal to 0. In a stricter sense, it is a Kepler orbit with the eccentricity greater than 0 and less than 1.
