Answer:
endothermic
Explanation:
An endothermic is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Answer:
Explanation:
For constructive interference in thin films by reflected light , the condition is
Path difference = 2μd = odd multiple of λ / 2
Where μ is refractive index of water , d is thickness of water medium and λ
is wavelength of light
λ = 4μd or 4μd / 3 or 4μd / 5
= 4 x 1.33 x 400 nm = 2128 nm
or 2128 /3 = 709.33 nm
or 2128 /5 = 425.6 nm
For destructive interference ( dim reflection )
2μd = multiple of λ = λ or 2λ or 3λ
2 x 1.33 x 400 nm =1064
or 1064 x 2 = 2128 nm
or 1064 x 3 = 3192 nm.
Answer:
For instance, an object is moving and we can say that a force is acting or must have been acted upon to cause the state of motion. When force is applied, it changes the position of the object concerning time resulting in motion. The motion, in other words, is described as a change in speed or change in direction.
