When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores
1/2 (150 N/m) (0.030 m)² = 0.0675 J
of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores
1/2 (150 N/m) (0.060 m)² = 0.27 J
Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J
Maximize the objective function p = 5x + 3y for the given constraints. X ≥ 0 y ≥ 0 3x + 6y ≤ 48 2x + 8y ≤ 56.
The maximized value of the objective function is 38
The objective function is given as:
Max P = 5x + 3y
The constraints are given as:
3x + 6y ≤ 48 2x + 8y ≤ 56x ≥ 0 y ≥ 0To do this, we make use of the graphical method.
See attachment for the graph of the constraints.
From the graph, we have the following feasible point
[tex](x,y) = (4,6)[/tex]
Substitute 4 for x and 6 for y in the objective function.
[tex]Max\ P = 5x + 3y[/tex]
So, we have:
[tex]P = 5 \times 4 + 3 \times 6[/tex]
[tex]P = 20 + 18[/tex]
[tex]P = 38[/tex]
Hence, the maximized value of the objective function is 38

Answer:
Explanation:
If an objective function has a maximum value, it will occur at one of the vertices of the feasible region (i.e., the solution region for the system of inequalities). The feasible region's vertices occur at (0, 0), (0, 7), (4, 6), and (16, 0).
Use the x- and y-value from each vertex to evaluate the objective function P = 5x + 3y.
(x, y) 5x + 3y P
(0, 0) 5(0) + 3(0) 0
(0, 7) 5(0) + 3(7) 21
(4, 6) 5(4) + 3(6) 38
(16, 0) 5(16) + 3(0) 80
Therefore, the maximum of the objective function is 80.

What is the frequency of a sound source that produces the same wavelength in 20∘c air?.
Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "115.87Hz."
What is the frequency of a sound source?The frequency of a sound source is the quantity of waves that move through a point per unit of time.
Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.
Therefore, in this case, we have
Velocity (v) of sound in air = 343 m/s
Wavelength (λ) = 2.96 m
Frequency (f) =?
f = v ÷ λ
f = 3.43m/s ÷ 2.96m
=> 115.87Hz
Hence, in this case, it is concluded that the correct answer is 115.87Hz.

Point e is drawn on the graph so that line ef is parallel to line cd. If the coordinates of point e are (, y), what is the value of y? −8 −4 0 8.
Based on the graph given, it can be deduced from the computation that the value of y will be -8.
Point C is given as (-10 , -2) and D = (10 , 6)
The Slope of line CD = ( 6 - (-2) /( 10 - (-10) = 8/20 = 2/5
Since EF is parallel to line CD , the slope of EF = 2/5
Equation y = (2/5)x + c
5y = 2x + 5c
It passes through F ( 6 , -4)
= 5(-4) = 2*6 + 5c
= -20 = 12 + 5c
5c = -32
5y = 2x - 32
Point E ( - 4 , y)
5y = 2(-4) - 32
5y = -8 - 32
5y = -40
y = -8
Therefore, the value of y is -8.

A 1. 5-kilogram lab cart is accelerated uniformly from rest to a speed of 2. 0 meters per second in 0. 50 second. What is the magnitude of the force producing this acceleration?.
The magnitude of the force producing this acceleration is found to be 3.0 N.
What is Force?Force may be defined as the process of pushing and pulling an object with an appropriate mass in order to cause it to change its velocity with respect to time.
Force is a vector quantity as it has both magnitude and direction. Force is an external agent which is generally capable of changing a body's state of rest or motion with respect to time.
According to the question,
The total mass of an object = 1.5 kg.
The speed of an object = 2.0 m/sec.
So, the formula for calculating the magnitude of the force is as follows:
Force = Mass × Acceleration.= 1.5 kg × 2.0 m/sec = 3.0 N.
Therefore, the magnitude of the force producing this acceleration is found to be 3.0 N.

What change in a population would you expect to see if a selection pressure was against the trait of a dominant allele in that population?.
Answer:
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.
