Answer:
Amplitude
Explanation:
Transverse waves such as water waves, sound waves and earthquakes usually contain a large amount of energy which is determined by the amplitude.
The amplitude is known as the maximum displacement and its measured in meters. We should also note that the energy of a wave doesn’t affect the wavelength, frequency or speed but only the amplitude.
Answer:
Option (C) Bromine (Br) has more electrons, which makes its energy sublevels more negative, which pulls them closer to the positively charged nucleus.
At the end the energy of the system is the same as 200 J.
<u>Explanation:</u>
It is a closed complex system and it has 200 J of energy.
Here the system is converting from one form to another form and then to another form.
As we know that there is a conservation of energy when one form is converted to another form without losing or gaining energy, whereas it may convert from one form to another form with the energy being conserved.
So after there is a conversion of one form to another form but there is no loss or gain of energy and same energy must be retained.
Answer:
First and seventeenth group.
Explanation:
Hydrogen is a special case as it has only one electron in its outermost orbital.
The hydrogen can lose or can accept electron easily.
Thus it can form positive ion similar to alkali metals and negative ion similar to halogens.
Thus it can fall into two groups
a) I group [Alkali metals]
b) 17th Group [Halogens]
