Answer:
Option (B)
Explanation:
In the stabilizing natural selection, the extreme traits from both the ends are eliminated by natural selection and natural selection favors the intermediate trait. So over time individuals having the intermediate traits are selected over the individuals having extreme traits.
So here the population of the bat which possesses moderate wing length is selected over the individual with extreme traits like individuals with short wings and long wings. As a result, the population of moderate length wing bats increased.
Therefore the correct answer is (B)- stabilizing natural selection.
Answer:
Explanation:
mass attached m = .14 kg
force constant k = 5N / m
displacement
= amplitude of oscillation
A = .03 m
A ) period of motion = 
= 2 x 3.14 
T = 1.05 s
B ) maximum speed of block = angular velocity x amplitude
= (2π /T) x A
= (2 x 3.14 x .03) / 1.05
= .1794 m / s
17.94 cm /s
C )
maximum acceleration = angular velocity² x amplitude
= (2π /T)² x A
= (2π /1.05)² x .03
= 1.073 m / s²
D )
position
S = A cos ωt , ω is angular velocity
S = .03 cos(2πt /T)
= .03 cos 5.98 t
v =ω A sin(2πt /T)
= 5.98 x .03 sin5.98t
= .1794 sin5.98t
acceleration = ω²A sin5.98t
= 1.073 sin5.98t
Answer:
vB = 12 m/s
W = 36 J
Explanation:
Potential energy converts to kinetic energy
½mv² = mgh
v = √(2gh)
vB = √(2(9.8)(7.1 - 0) = 11.796609... m/s
W = mg(hA) - mg(hB) = 0.8(9.8)(7.1 - 2.5) = 36.064 J
Given what we know, the statement that "if the part you are designing is completely symmetric, you can complete the part by designing just half of the part and using one mirror feature" is true.
<h3>Why is this statement true?</h3>
Symmetry is when something is exactly the same on either side.
This line can be drawn anywhere but is most commonly a vertical line splitting the object in question down the middle.
Since the object is identical on both sides, using a mirror to flip the completed half to the other side, will effectively give you the finished product.
Therefore, given that when something is entirely and perfectly symmetric it will be exactly the same on either side, it is true to say that by designing half of the end product and using a mirror effect to flip it to the other side, you can complete it.
