Refraction and reflection both shows the wave property of light and the difference between them is that during reflection the medium of light will not change while in refraction the light will change its medium
so in reflection of light we use that angle of incidence = angle of reflections with respect to normal
While in refraction we use Snell's law
Diffraction of light is the phenomenon of light in which light will bend at the corners and enter into the region of dark
While absorption is the phenomenon of energy absorption when light incident on any medium or surface
Answer:
A
Explanation:
I think that if the object is a conductor, it would want all of that electricity, attracting the object
To solve this problem, it is necessary to apply the concepts related to the change of entropy in function of the Volume in two states due to the number of moles and the ideal gas constant, this can be expressed as
Where,
R = Gas constant
V = Volume (at each state)
At the same time the number of moles of gas would be determined by the ideal gas equation, that is,
Where,
P = Pressure
V = Volume
R = Gas Constant
T = Temperature
Using the value of moles to replace it in the first equation we have
Therefore the correct option is A.
Answer
Hi,
The forces are; weight (gravity), Normal/centripetal force and friction. Force due to gravity is constant where as friction and centripetal are not.
Explanation
Weight is constant, given by the force of gravity on the object. The centripetal force is a function of the angles occurring between the velocity vector and the weight vector that is at right angle with the perpendicular line drawn from the surface. Friction is a function of the centripetal force thus it also varies.
Hope this helps!
