Evaporation would be the answer.
The beaker which consists of water at a temperature of 45℃ represents ‘The average kinetic energy of water particles’.
<u>Explanation:
</u>
According to ‘Kinetic Molecular Theory of water’ the average kinetic energy of atoms in a system is directly proportional to its temperature. So, this explains that the kinetic energy in between the inner particles of water which is in the beaker is something which represents the temperature of the water as 45℃. This kinetic energy is produced due to the moment of particles of the matter. (A liquid is the second state of matter which is prepared by tiny particles, such as atoms, inter-molecular bonds between the particles helps these atoms to hold together)

Answer: 168.75 N
Explanation:
first, let's convert microcoulombs to coulombs
q1 = 1e-4 C
q2 = 3e-5 C
r = 0.4 m
then use the equation Fe =
plug in values --> F = (9e9*1e-4*3e-5)/(0.4)^2
F = 168.75 N
Answer:
1. Absorption or Emission of the light
2. Light induced changes in the matter
Explanation:
When an electromagnetic wave such as light interacts with solid, two consequences are for sure:
1. Absorption or Emission of the light
2. Light induced changes in the matter
When light travels through the solid, the intensity of light decreases as a result of addition of light energy to the body to which it interacts. If the medium or body to which light interacts is low in absorbing due to its atomic structure inside then light passing through it will show it. On the contrary, if a material is high in absorbing, very less intensive light will travel out.
Moreover, there will ionization of the atoms inside the medium to which light interacts. As light carries energy and when it interacts with atoms of the body, atoms gets energy and excited or de-excited accordingly.
Hence, above are the two primary consequences of this interaction.
Answer:
Explanation:
Volume of lead object = volume of aluminium object = V
mass of lead object > mass of aluminium object
When both the objects immersed in water, the buoyant force acting on both the objects.
Buoyant force = Volume immersed x density of water x gravity
As the volume of both the objects is same, so the buoyant force acting on both the objects is same.
So, weight in air of lead object is more than the weight in air of aluminium object.
