Hydrogen i suppose is the right one
Answer:
Basically, the more hot the state is, the more kinetic energy it will have. This means that answer D. would be right, as it goes from coldest to hottest states!
Answer:
Ammonia is the richest source of nitrogen on a mass percentage basis because it has 82.35% of nitrogen by mass.
Explanation:
Percentage of element in compound :
(a) Urea, 
Molar mass of urea = 60 g/mol
Atomic mass of nitrogen = 14 g/mol
Number of nitrogen atoms = 2
(b) Ammonium nitrate, 
Molar mass of ammonium nitrate = 80 g/mol
Atomic mass of nitrogen = 14 g/mol
Number of nitrogen atoms = 2
(c) Nitric oxide, NO
Molar mass of nitric oxide = 30 g/mol
Atomic mass of nitrogen = 14 g/mol
Number of nitrogen atoms = 1
(d) Ammonia, 
Molar mass of ammona = 17 g/mol
Atomic mass of nitrogen = 14 g/mol
Number of nitrogen atoms = 1
Ammonia is the richest source of nitrogen on a mass percentage basis because it has 82.35% of nitrogen by mass.
A. They are the most destructive earthquake waves.
D. They can move in a rolling pattern through rock, like an ocean wave.
Explanation:
Surface waves are seismic waves that cause the most destruction during an earthquake.
Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.
- Seismic waves are elastic waves that notably transmits energy.
- They usually accompany earthquakes.
- There are two broad categories of these waves.
- Surface and body waves.
- Seismic surface waves are low frequency and long wavelength waves.
- They travel very close to the surface.
- They are made up of Love and Rayleigh waves.
- Love waves travels laterally in a horizontal fashion.
- Rayleigh waves rolls like ocean waves in the ground.
- The bulk of the destruction caused during an earthquakes is due to these waves.
- They are the last waves to arrive a seismic station

The answer for the following questions is explained below.
Explanation:
The two variables that affect kinetic energy are:
- mass and
- velocity
- velocity - The faster an object moves,the more the kinetic energy it has.
- mass - Kinetic energy increases as mass increases
The kinetic energy of an object depends on both its mass and its velocity
Kinetic energy increases as mass increases
For example,think about rolling a bowling ball and a golf ball down a bowling lane at same velocity
Here,the bowling ball has more mass than the golf ball
Therefore you use more energy to roll the bowling ball than to roll the golf ball
The bowling ball is more likely to knock down the pins because it has more kinetic energy than the golf ball
