Answer:
A scientific model is a way of representing a system to better understand it's behavior
Explanation:
speed of the car is given on the road

reaction time is given as

now we can find the distance that it will move during this reaction time

now the deceleration of the car is 10 m/s^2
so the distance that it will move before stop is given by



so the total distance that it require to stop is given as

while the deer is standing at distance 38 m
so the car will stop 2.8 m before the position of deer
The compression curve would be theoretically given for a system of bodies in which the spring applies the force (Although in the same way the following process can be extrapolated to any system, depending on the type of Force to consider) For a spring mass system, the strength is given by Hooke's law as

Where,
K = Spring constant
x = Displacement
If we integrate based on distance we would have

This integral represents the area under the Force Curve based on each distance segment traveled.



This is the same formula that represents the elastic potential energy of a body. Therefore the correct answer is D.
Answer:
32 amu is the right choice because both protons and neutrons have a mass of 1 amu. Electrons have no mass so go with the last choice
