Write a report on the lap experiment: Motion with Constant Acceleration
Answers
Answer:
Purpose: To observe how an object’s position and velocity change while it is moving with a constant acceleration.
Question: How does an object’s position and velocity change as the object accelerates?
Hypothesis: If the fan speed increases, then the acceleration of the cart increases, because a greater fan speed supplies more energy to move the cart.
Variables:
• Independent variable: fan speed
• Dependent variable: acceleration of the cart
• Controlled variables: mass
Materials:
• Cart with Fan (1 kg)
• CM ruler (1 cm)
• Stop watch (0.0 cm pe sec)
• Flag
Procedure:
1. Use the setup on “Force and Fan Carts” Gizmo.
2. First, put the fan speed on low and no friction surface.
3. Press the start button and record the final time when the cart crosses the finished line. Record on table B.
4. Then, click on the data tab to record the speed data, total distance, average velocity, and acceleration. Record on table A and B.
5. After, observe the position vs. time graph with the speed and line graph toggled. Record on table C.
6. Repeat steps 2-5 on fan speed on medium and high with no friction surface.
7. Next, reset and put fan speed on low.
8. Press start and pause on 4 seconds.
9. On the same trial turn off the fan speed and hit start again.
10. Observe the graph and write observations on table D.
Analysis and Conclusion:
In conclusion, my hypothesis matches the data, because the data shows that increasing the fan speed increases the acceleration of the cart. The trends for all fan speeds are linear slope for speed. The higher the fan speed, the less time it took for the cart to cross the finish line.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.
What is the velocity?Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.
Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.
v = d / t
Where v is the velocity, d is the distance covered and t is the time taken by the body.
The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).
Given, the distance traveled by the vehicle, d = 100 m
The time taken by vehicle = 0.246 sec
The velocity of the vehicle, v = 100/0.246 = 406.5 m/s
We know that 1km = 1000m then 1 m = 10⁻³ Km
1 hour = 60 ×60 = 3600 s
1s = 1/3600 hr
Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)
v = 1463.4 Km/hr

#SPJ2
Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s
To convert m/s to km/hr, we need to multiply the velocity by 3.6:
Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr
The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.
What will happen when you slide the sponges in different directions?
Answers
Transform boundary
is the answer from stemscopes
The sponges will contract when there is a slide of sponges in different directions.
What are the sponges?Sponges are called as the members of the phylum Porifera. This is a basic animal group and the diploblasts' sibling. They are multicellular creatures with pores and channels that let water to move through their bodies, which are made of jelly-like mesohyl sandwiched between two thin layers of cells.
Sea sponges were among the earliest animal groups to form on Earth, but new chemical evidence puts their appearance 120 million years earlier than previously assumed, according to New Scientist.
According to the research, it is found that When there is a sliding of sponges in opposite directions, the sponges will compress. As water filters through the porous shell of a sponge, it develops motion, obtains food and oxygen, and expel waste.
Therefore, Flagella, microscopic hairlike structures inside the sponge, produce currents that filter germs out of the sponge's cells and trap food within them.

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum). According to Newton's third law, the forces on the two objects are equal in magnitude.

Allie took archery lessons and became proficient after several months. She placed the arrow into the bowstring, pulled it back, and released the arrow. She did not hit the bull's-eye, so she decided to shoot another arrow. Describe the kinds of energy she demonstrated in each step of the process, and how they changed.
Answers
At this stage, Allie primarily exhibits potential energy. The arrow possesses potential energy due to its position and the forces acting upon it. The potential energy is stored in the bowstring, which is stretched when the arrow is placed.
Pulling back the bowstring:
As Allie pulls back the bowstring, she exerts force, converting her muscular energy into elastic potential energy. The energy is stored in the flexed bowstring and the limbs of the bow. The further she pulls back, the more potential energy is accumulated in the bow.
Releasing the arrow:
When Allie releases the bowstring, the potential energy stored in the bowstring and limbs is rapidly transformed into kinetic energy. The potential energy is converted into the energy of motion as the bowstring snaps forward, propelling the arrow forward.
Arrow in flight:
As the arrow moves through the air, it possesses kinetic energy. The energy of motion is determined by the arrow's mass and velocity. The arrow's kinetic energy gradually decreases as it encounters air resistance and gravity.
During these steps, the energy transformations occur as follows:
Allie converts her muscular energy into potential energy when pulling back the bowstring.
The potential energy stored in the bowstring and bow limbs is transformed into kinetic energy when the arrow is released.
The arrow then travels through the air, converting its kinetic energy into other forms, such as heat due to air resistance and gravitational potential energy as it rises and falls.
It is important to note that there may be other forms of energy involved, such as thermal energy from the friction between the arrow and the bow or the surrounding air.
In each step of the archery process, Allie demonstrates different forms of energy.
Throughout the process, the kinds of energy involved change. Initially, Allie deals with potential energy in the arrow and the bowstring. Then, she converts her muscular energy into elastic potential energy when pulling back the bowstring. Upon release, the elastic potential energy transforms into kinetic energy in the arrow. Finally, during flight, the arrow primarily exhibits kinetic energy.
While placing the arrow into the bowstring, Allie is mainly dealing with potential energy. The arrow possesses potential energy due to its position relative to the ground. When Allie is Pulling back the bowstring, she exerts force, converting her muscular energy into elastic potential energy. The potential energy in the stretched bowstring increases as she pulls it farther back.
Allie releases the arrow, hence the stored elastic potential energy in the bowstring is rapidly converted into kinetic energy. The arrow gains kinetic energy, which is the energy associated with its motion.

What is a Box Camera
Answers
A box camera is a simple type of camera, the most common form being a cardboard or plastic box with a lens in one end and film at the other. They were sold in large numbers during the late 19th and early 20th centuries. The lenses are often single element designs meniscus fixed focus lens, or in better quality box cameras a doublet lens with minimal (if any) possible adjustments to the aperture or shutter speeds. Because of the inability to adjust focus, the small lens aperture and the low sensitivity of the sensitive materials available, these cameras work best in brightly lit day-lit scenes when the subject is within the hyperfocal distance for the lens and of subjects that move little during the exposure. Eventually, box cameras with photographic flash, shutter and aperture adjustment were introduced, allowing indoor photos.
