A 76-kg water skier is being pulled by a nylon (Young's modulus 3.7 x 109 N/m2) tow rope that is attached to a boat. The unstretched length of the rope is 19 m and its cross-section area is 1.6 x 10-5 m2. As the skier moves, a resistive force (due to the water) of magnitude 140 N acts on her; this force is directed opposite to her motion. What is the change in length of the rope when the skier has an acceleration whose magnitude is 0.61 m/s2?

Answer:

smog. Just trust me im sure its right.

Answer:The solution is in the attached file below

Explanation:

The value of r is approximately 0.56. The closest option is D) π / 0.56, which is equal to approximately 5.6 when π is approximated to 3.14.

Using the arc length formula, s = rθ, we can rearrange it to find the missing variable r:

r = s / θ

Given that s = 26.4 and θ = 3π/2, we can substitute these values into the formula:

r = 26.4 / (3π/2)

To divide by a fraction, we can multiply by its reciprocal:

r = 26.4 * 2 / (3π)

Now, we simplify:

r = 52.8 / (3π)

To express r in terms of π, we divide:

r ≈ 52.8 / (3 * 3.14)

r ≈ 5.6

Therefore, option D) is the correct answer.

Carnivores

Explanation:

A carnivore is an organism that mostly eats meat, or the flesh of animals. Sometimes carnivores are called predators. Organisms that carnivores hunt are called prey.

Carnivores are a major part of the food web, a description of which organisms eat which other organisms in the wild. Organisms in the food web are grouped into trophic, or nutritional, levels. There are three trophic levels. Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, organisms that eat plants and other autotrophs, are the second trophic level. Carnivores are the third trophic level. Omnivores, creatures that consume a wide variety of organisms from plants to animals to fungi, are also the third trophic level.

Answer:

The correct choice is D. Concentric exercise can be hard on joints, so she should be very careful.

The best advice for Elsa is she is probably using the stair machine wrong if the soreness resides for a long time. Therefore, option (B) is correct.

Exercise can be described as the body activity that enhances or maintains physical fitness, wellness, and overall health.

Exercise can be performed for various reasons, to aid growth, develop muscles, improve strength, and the cardiovascular system, honing athletic skills, weight loss or maintenance, and simply for enjoyment.

Many people choose to exercise outdoors where they socialize and improve their well-being as well as their mental health.

The amount of recommended exercise depends upon the type of exercise, goal, and age of the person in terms of health benefits, Even doing a small exercise can be healthier than doing nothing.

Any exercise causes soreness, but if soreness resides for a long time, it can be time to analyze your exercise and modifies it in an appropriate way.

Therefore, if the soreness resides for a long time, then Elsa is probably using the stair machine wrong.

Explanation:

The time required for the ball to roll down the given distance is 4 seconds.

Given the data in the question;

Since the ball started from rest,

To determine the time required for the ball to travel the given distance, we use the Second Equation of Motion:

[tex]s = ut + \frac{1}{2}at^2[/tex]

Where s is distance traveled, u is initial velocity, a is acceleration and t is time taken.

We substitute our given values into the equation and solve for "t"

[tex]40m = [ 0*t ] + [ \frac{1}{2}\ *\ 5.0m/s^2\ *\ t^2 ]\\\\40m = 2.5m/s^2\ *\ t^2\\\\t^2 = \frac{40m}{2.5m/s^2}\\\\t^2 = 16s^2\\\\t = \sqrt{16s^2}\\\\t = 4s[/tex]

Therefore, the time required for the ball to roll down the given distance is 4 seconds.

Answer:

facts provided or learned about something or someone.

As the spring returns to it's equilibrium position, it performs

1/2 (4975 N/m) (0.097 m)² ≈ 23 J

while the gravitational force (opposing the block's upward motion) performs

-(0.244 kg) g (0.097 m) ≈ -2.3 J

of work on the block. By the work energy theorem, the total work done on the block is equal to the change in its kinetic energy:

23 J - 2.3 J = 1/2 (0.244 kg) v² - 0

where v is the speed of the block at the moment it returns to the equilibrium position. Solve for v :

v² = (23 J - 2.3 J) / (1/2 (0.244 kg))

v = √((23 J - 2.3 J) / (1/2 (0.244 kg)))

v ≈ 44 m/s

After leaving the spring, block is in free fall, and at its maximum height h it has zero vertical velocity.

0² - (44 m/s)² = 2 (-g) h

Solve for h :

h = (44 m/s)² / (2g)

h ≈ 2.3 m

The sun's thermal energy serves as the primary energy source for producing atp during the photosynthesis process. Essentially, it serves as the primary catalyst for all metabolic processes in plants. Protons diffusing through the F0 section of ATP synthase

All living things contain the energy-carrying molecule adenosine triphosphate (ATP) in their cells. When food molecules are broken down, chemical energy is released that is captured by ATP and used to power other cellular operations.

To drive metabolic events that would not happen naturally, to transfer necessary molecules across membranes, and to do mechanical labor, such as moving muscles, cells need chemical energy.

Chemical energy cannot be stored by ATP; lipids and carbohydrates such as glycogen serve this purpose. ATP is created when energy from storage molecules is required by the cell.
