Answer:
B. Wave-like way with a pattern that is wave-like
Explanation:
The double slit experiment when performed with electromagnetic waves, gives a pattern of light lines and dark areas, equally spaced.
In the case of electrons we must use Broglie's duality principle that states that all things have the characteristics of particles and waves together. The characteristic observed in a given experiment depends on the type of experiment, using the relationship
p = h /λ
Where p is the amount of motion of the particle and λ the wavelength associated with this particle
In consequence of the previous one to the screen it should arrive as a wave with a wave type pattern
Let's review the answer.
A) False. The pattern is wave type
B) True. The whole process is with undulating characteristics
C) False. A wave arrives
D) False. A wave arrives
Answer:
Your answer will be 6.0kg•m/s
Explanation:
In the given question all the required details d given. Using these information's a person can easily find the momentum of the object. In the question it is already given that the mass of the object is 5 kg and the velocity at which it is traveling is 1.2 m/s.We know the equation of finding momentum asMomentum = mass * velocity = 5 * 1.2 = 6So the momentum of the object is 6 Newton.
Answer:
Pinhole Projection
Explanation:
You will get a great view if you project a sunlight coming thrugh a small hole onto a viewing card enclosed in a long box. The smaller the pinhole, the sharper the image
Answer : The change in enthalpy of the reaction is, -310 kJ
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The given main reaction is,
The intermediate balanced chemical reaction will be,
(1) 
(2) 
(3) 
Now we will reverse the reaction 1 and multiply reaction 1 by 2, reaction 2 by 2 and reaction 3 by 3 then adding all the equations, we get :
(1) 
(2) 
(3) 
The expression for enthalpy of formation of 
will be,
Therefore, the change in enthalpy of the reaction is, -310 kJ
5.6 which would be acidic!
