Final answer:
A truck will have more no-zones or blind spots due to its size. Advertisements and the number of passengers are unrelated to size. A heavily loaded trailer may bounce slowly because of the increased damping effect of the mass
Therefore, the correct answer is a. More no-zones or blind spots.
Step-by-step explanation:
A truck, because of its size, will have more no-zones or blind spots. These are areas around the truck where the driver has limited or no visibility. It's crucial for other drivers on the road to be aware of these no-zones to prevent accidents. However, the presence of advertisements on a trailer or the number of passengers is not directly related to the truck's size.
When observing a truck's behavior on the road, such as a trailer bouncing up and down slowly, several factors could be at play. If a trailer bounces slowly, it's possible that the trailer is heavily loaded.
A heavy load will often cause a trailer to move with a lower frequency of oscillation, due to the increased damping effect of the mass. Conversely, an empty trailer might bounce more rapidly due to less weight and therefore less natural damping.
A truck, because of its size, will have more no-zones or blind spots compared to smaller vehicles. These are areas around the truck where the driver's visibility is limited or obstructed. Due to its large dimensions, a truck has more areas that are not directly visible to the driver, such as the sides and rear of the trailer.
Therefore, the correct answer is a. More no-zones or blind spots.
