a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
Explanation:
A transverse wave is a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
A wave is a disturbance that transmits energy from one place to another.
There are two major types of waves:
- Transverse waves are waves that are propagated perpendicularly to the direction of the wave.
- A wave in string going up and down is a transverse wave.
- Electromagnetic waves are transverse waves.
- Seismic s-waves are transverse waves.
- Sound waves are longitudinal waves propagated parallel to their source.

Greater density means to greater mass and greater mass to more gravity on the body
The number of valence electron in sodium is 1 and that in chlorine are 7. In order to complete the octet (8 electrons in outermost shell) sodium can give its valence electron to an atom with more electronegativity. Here, chlorine is more electronegative than sodium, due to 7 valence electrons it required one more electron to complete its octet.
Therefore, chlorine can take 1 valence electron of sodium to form ionic bond. In the ionic compound so formed, both sodium and chlorine have complete octets. In aqueous solution they exist as 
and 
ions, the positive charge on sodium indicates that it donates its one electron and negative charge on chlorine indicates that it accepts an electron.
All this happen due to difference in electronegativity of sodium and chlorine (chlorine is more electronegative than sodium).
Answer:
(2)×(9.8)×(0.76)
Explanation:
Given data:
Mass of bottle = 2 kg
Given height = 0.76 m
Gravitational potential energy of bottle = ?
Solution:
Formula:
Gravitational potential energy = mgh
g = 9.8 m/s²
Now we will put the values in formula.
Gravitational potential energy = 2kg×9.8 m/s²×0.76 m
Gravitational potential energy = 14.896 kg.m².s⁻²
j = kg.m².s⁻²
Gravitational potential energy = 14.896 j
