Answer:
Gamma radiation .
Explanation:
Three types of emission result at the time of nuclear emission .
alpha emission
Beta emission
Gamma radiation emission
Gamma radiation results in the emission of gamma ray . This is a very high frequency radiation . It is not a particle having charge and mass like alpha and beta emission . So it has no effect on the mass and charge of the product that is formed after gamma radiation . The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product . It causes negligible change in the mass of the product and no change in the charge of the product.
That is why , generally this product is not written in the nuclear reaction .
Hannah comes to a rest in <em>t</em> = 0.4 s, so her acceleration is
<em>a</em> = (0 - 25 m/s) / (0.4 s) = -62.5 m/s²
(that is, the acceleration points in the direction opposing her movement forward as she brakes)
Then the force exerted on her by the seatbelt has magnitude
<em>F</em> = (65 kg) (62.5 m/s²) = 4062.5 N ≈ 4063 N
The gravitational attractions are greatest be when the objects have large masses and they're closer together. Their sizes don't matter.
Answer:
Summarized
Explanation:
Among the many hypotheses proposed for the origin of the moon the four main are summarized as
the fission hypotheses in which moon was once a part of earth but got separated due to collision. The second hypotheses is that the moon formed along with the Earth but independently.Moon was formed else where in the solar system and got captured by the Earth's gravitational pull. The newer giant impact hypotheses suggest that a mars sized object grazed Earth, Ejecting material from both Earth and itself, that material condensed to form moon.
The motion of the branch being shaken causes the fruit to detach off the branch, and gravity helps make the fruit fall.
