Answer:

S = V t - 1/2 a t^2      a here is negative due to deceleration

S = 4 * 8 - 1/2 * 64 = 0

The object just returns to its original starting point

It started out at 8 m/s which was reduced to 0 m/s after 4 sec

In 4 more seconds it was moving at -8 m/s, just the opposite of where it started

State the methods of nuclear fission waste disposal and the suitability of each method.
Alexeev081 [22]
<span>Most low-level radioactive waste (LLW) is typically sent to land-based disposal immediately following its packaging for long-term management. This means that for the majority (~90% by volume) of all of the waste types produced by nuclear technologies, a satisfactory disposal means has been developed and is being implemented around the world.
</span>

Radioactive wastes are stored so as to avoid any chance of radiation exposure to people, or any pollution.The radioactivity of the wastes decays with time, providing a strong incentive to store high-level waste for about 50 years before disposal.Disposal of low-level waste is straightforward and can be undertaken safely almost anywhere.Storage of used fuel is normally under water for at least five years and then often in dry storage.<span>Deep geological disposal is widely agreed to be the best solution for final disposal of the most radioactive waste produced.

I've been getting this question wrong and i still don't know it.
RideAnS [48]

Answer: Option (A) is the correct answer.

Explanation:

Laser helps in zooming an image on which it is directed or falls so that it becomes easier for a large population to understand what the teacher or guide is talking about.

For example, when Greg is giving slide show presentation to a large audience then in order to make his slides visualized by everyone in the room he uses laser.

Therefore, we can conclude that a laser best help him with the presentation as he can use the laser to enlarge images on the slides.
