You are studying a population of flowering plants for several years. When you present your research findings you make the statem

ent that, "Increased allocation of resources to reproduction relative to growth diminished future fecundity." Which of the following graph descriptions could accurately present your data?
a) With seeds in the current year on the y-axis and seeds in the previous year on the x-axis, you would see a line that increased from left to right
b) With survivorship on the y-axis and number of seeds produced on the x-axis, you would see a line that decreased left to right.
c) With leaf area on the y-axis and number of seeds produced on the x-axis, you would see a line that increased left to right
d) With survivorship on the y-axis and number of seeds produced on the x-axis, you would see a line that increased left to right.
e) With seeds in the current year on the y-axis and seeds in the previous year on the x-axis, you would see a line that decreased from left to right

Answer:

Option A

Explanation:

The graph for this problem must depict the following ""Increased allocation of resources to reproduction relative to growth diminished future fecundity."

Hence, the survivor ship must be on the Y axis and the resources on the X axis.

Here the resources include the number of seeds produced.

hence, the higher is the number of seeds (resource), the lower is the survivorship (future fecundity)

Hence, option A is correct

2. An 873 kg dragster accelerates at a rate of 44.6 m/s during a race.
Ira Lisetskai [31]

Answer:

<h3>38,673.9N</h3>

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

<em>Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N</em>

A man stands on roof of a house and drops a ball of mass M (from rest) from a height of 10 m above the ground. Its speed just be
horsena [70]

Answer:

Vf = 14 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics, which is independent of the mass of the object.

v_{f} ^{2} =v_{o} ^{2} +(2*g*x)

where:

Vf = final velocity [m/s]

Vo = initial velocity = 0

g = gravity acceleration = 9.81 [m/s²]

x = distance = 10 [m]

Now replacing:

Vf² = 0 + (2*9.81*10)

Vf = 14 [m/s]

A whistle produces sound of frequency of 1.00 kHz. If a listener moves with a speed of 30 m/s away from the whistle, what freque
Serggg [28]

Answer:

The frequency the listener hears is 911.765 Hz.

Explanation:

The speed of a sound is 340 m/s

The speed of listener is 30 m/s in a direction away from the whistle.

The speed of the listener with respect to the sound waves from the whistle

= ( 340 - 30) m/s

= 310 m/s

This because the direction of the sound waves from the whistle and the direction of travel of the listener are the same, that is, both are traveling away from the whistle.

Therefore from the formula we get

⇒     \frac{f_2}{f_1}  = \frac{v_2}{v_1}            ⇒  f_2 = 1000 \times \frac{310}{340}  = 911.765 \hspace{0.1cm} Hz

The frequency the listener hears is 911.765 Hz.
