Because of the build up of pressure. There is so much steam coming from such a compressed point, it’s coming out in force.
Now think of that same spot being closed, it only has one place to go but it can’t leave, so that pressure will build and build and then BOOM, it explodes.
In short, the answer is the pressure being released from a small point, and how that energy is released.
Answer:
Explanation:
Electrons are allowed "in between" quantized energy levels, and, thus, only specific lines are observed. <em>FALSE. </em>The specific lines are obseved because of the energy level transition of an electron in an specific level to another level of energy.
The energies of atoms are not quantized. <em>FALSE. </em>The energies of the atoms are in specific levels.
When an electron moves from one energy level to another during absorption, a specific wavelength of light (with specific energy) is emitted. <em>FALSE. </em>During absorption, a specific wavelength of light is absorbed, not emmited.
Electrons are not allowed "in between" quantized energy levels, and, thus, only specific lines are observed. <em>TRUE. </em>Again, you can observe just the transition due the change of energy of an electron in the quantized energy level
When an electron moves from one energy level to another during emission, a specific wavelength of light (with specific energy) is emitted. <em>TRUE. </em>The electron decreases its energy releasing a specific wavelength of light.
The energies of atoms are quantized. <em>TRUE. </em>In fact, the energy of all subatomic, atomic, and molecular particles is quantized.

#1
for the block of mass 5 kg normal force is given as
friction force is given as
Net force is given as
now we know that
#2
Normal force is given as
now we know that
as object moves with constant velocity
now for coefficient of friction we can use
#3
net force upwards is given as
mass is given as
now as per newton's law we can say
#4
As we know that when block is sliding on rough surface
part a)
net force = applied force - frictional force
part b)
for coefficient of friction we can use
here normal force is given as
now we have
#5
if an object is initially at rest and moves 20 m in 5 s
so we can use kinematics to find out the acceleration
now net force is given as
#6
an object travelling with speed 25 m/s comes to stop in 1.5 s
so here acceleration of object is given as
now the force is gievn as
The macromolecule that is made up of subunits that are called amino acids are the protein. The answer is therefore letter D. The carbohydrates are made up of subunits called monosaccarides. The lipids are mades up of subunits referred to as the fatty acid while nucleic acid are made up of nucleotides.
