Answer:
Diagrams are essential to provide a clear, unambiguous picture. They can be put together in meetings, can make discussions easier than lots of text and are quicker and easier to do iterations and re-work.
Explanation:
Diagrams play an important role in statistical data presentation. Diagrams are nothing but geometrical figures like lines, bars, circles, squares, etc. Diagrammatic data presentation allows us to understand the data in an easier manner.
A block of mass 0.244 kg is placed on top of a light, vertical spring of force constant 4 975 N/m and pushed downward so that the spring is compressed by 0.097 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise
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

Using the Arc length formula s = r θ, find the missing variable. Find r when s = 26.4 and θ = 3π/2.
A) 39.6/ π
B) π /17.6
C) 17.6/ π
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.

A rescue pilot drops a survival kit while her plane is flying at an altitude of 2000.0 m with a forward velocity of 100.0 m/s. If air friction is disregarded, how far in advance of the starving explorer's drop zone should she release the package?
Answer:
H = 1/2 g t^2 no original vertical velocity
t = (2 * 2000 / 9.8)^1/2 = 20.2 s
Sx = 100 m/s * 20.2 s = 2020 m
A rescue pilot drops a survival kit while the plane is flying at an altitude of 2000 m then the distance travelled by the package after the drop will be 2020 meters.
What is Friction?A force that prevents two solid objects from smoothly sliding or rolling over one another is known as friction. While frictional forces, such as the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion. To overcome frictional forces in the moving parts, automotive engines use about 20% of their total power.
The main contributor to friction between metals appears to be adhesion, or the forces of attraction, between the contact regions of the surfaces, which are always microscopically uneven.
According to the question,
H = 1/2 g t²
2000 = 1/2(9.8) t²
t² = 4000/ 9.8
t = 20.2 seconds.
So the distance travelled by the package will be :
Distance = s × t
Distance = 100 m/s × 20.2 s
Distance = 2020 meters.

Elsa has been spending a lot of time on the stair machine at her gym. She is starting to feel really sore in her knees, but she figures that it is not a big deal since exercise often makes people ache. What is the BEST advice for Elsa?
A.
She is right to think that soreness is part of working out.
B.
She is probably using the stair machine wrong if she is sore.
C.
The soreness means that the concentric exercises are doing their job.
D.
Concentric exercise can be hard on joints, so she should be very careful.
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.
What do you mean by Exercise?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.

Animals which only consume other animals are called
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.
