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:
The final velocity is -49.05 meters per second.
Explanation:
Let's use an equation of constant acceleration:
Where a is the acceleration and g is the acceleration caused by gravity.
Since the object is being dropped from rest, .
We're looking for the speed after 5 seconds, so .
So the final velocity is -49.05 meters per second.
