Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h, hence Truck B will have a greater stopping distance.
The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.
From the following expression
Speed = Distance/Time
Distance = Speed*Time
More on the kinetic Energy
Following from the given problem truck B will also have more kinetic energy because it velocity is more
Formula
KE= 1/2mv^2
Hence the more the velocity for a constant mass the greater the Kinetic energy

Answer:
(c)-All results for the experimental groups involving wing surgery would be invalid.
Explanation:
The study researcher shown in the above question noted that flies that underwent wing surgery were more attacked than those that received no wing treatment. However, the researcher does not show the study variables and, consequently, does not show any relationship between the variables and the research result. For this reason, we can state that based on this result, all results for experimental groups involving wing surgery would be invalid.
C I did this question before
I think one must rotate the pt into a supine position and protect her spine.
Supine position means lying horizontally with the face and torso facing up, as opposed to the prone position, in which is face down. When used in surgical procedures, it allows access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities.
Multiply by the power of 10x and you get your answer. Which is by to ten.
