Answer:
Transverse wave- Back and forth at right angles to the direction of the wave arrow.
longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.
electromagnetic wave- two alternating waves moving at right angles to each other.
Explanation:
In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.
In a transverse wave, the particles vibrate parallel to the wave motion
Electromagnetic waves occur as a result of the interaction between two waves and are normally transverse in nature.
Answer:
Explanation:
m = Mass of object = 
m' = Mass of water = 
= Density of object
= Density of water
Weight of the water displaced is the force in the case of floating objects
According to the question
In the case of floating objects
The ratio of the density of the object to that of water is
Answer:
0
Explanation:
Displacement is a vector from initial to final point. Because initial and final point are the same, so displacement is 0.
They have the same number of electrons in their outermost shell
Explanation:
Lithium, sodium, potassium, rubidium, cesium and francium are in the same column on the periodic table because they have the same number of electrons in their outermost shell.
- The periodic table is based on the precepts of the modern periodic law which states that "the properties of elements are a periodic function of their atomic number".
- In the table elements having the same number of electrons in the outermost shell of their atoms are placed over one another in vertical columns.
- Each of the resulting vertical column is known as a group or family.
- The given elements belongs to the first family on the periodic table.
- In this group, all the elements have just one electron in their outermost shell.
