Answer:
Explanation:
acceleration is the time rate of change of velocity
a = (51 - 20) / 3 = 10⅓ mi/hr/s
which should probably be converted to standard units.
10⅓ mi/hr/s(5280 ft/mi) / 3600 s/hr) = 15.15555... ≈ 15.2 ft/s²
which is roughly half the acceleration of gravity.
The ones that interact would be Atmosphere, biosphere, and cryosphere. :)
<h2>
Answer: By the double slit experiment applied to electrons</h2>
The French physicist Louis De Broglie proposed the existence of matter waves, that is to say that <u>all matter has a wave associated with it.</u>
On the other hand, Heisenberg enunciated the uncertainty principle, which postulates that the fact that <u>each particle has a wave associated with i</u>t, imposes restrictions on the ability to determine its position and speed at the same time.
These postulations were tested with the double slit experiment (formerly applied to photons) applied to electrons, and the result was: electrons (as well as the other particles different from the photons) are able to behave as waves.
Its (a) and(a)for the other ? and the last one is (d)
Answer:
Yes, a body with a certain velocity can have an opposite acceleration, the acceleration would then be negative, since it is opposite to the direction to the velocity and also because the direction in which the acceleration is portrayed is on the left-hand side.
Hope this answer helps :)
