A body freely falling under the action of gravity passes two points 10 metres apart vertically In 0.2s. From what height, above the higher point did it start to fall?
Answers
Answer:
Explanation:
We can use the equation for free fall motion to solve this problem:
h = (1/2)gt^2
where:
h = height from which the body started to fall (what we want to find)
g = acceleration due to gravity (9.8 m/s^2)
t = time taken to fall 10 meters (0.2 s)
First, we need to find the velocity of the body when it passes the lower point. Since the body is freely falling, it will have the same velocity as an object thrown vertically downward from rest at the height from which it started to fall (h). We can use the equation for final velocity in free fall to find this velocity:
vf^2 = vi^2 + 2gh
where:
vf = final velocity (which is the velocity when the body passes the lower point)
vi = initial velocity (which is zero)
g = acceleration due to gravity (9.8 m/s^2)
h = height from which the body started to fall (what we want to find)
Rearranging the equation and substituting the known values, we get:
vf = sqrt(2gh)
vf = sqrt(2 × 9.8 m/s^2 × h)
vf = sqrt(19.6h) m/s
Now we can use this velocity to find the time taken by the body to travel the 10-meter distance between the two points:
vf = gt
t = vf/g = sqrt(19.6h)/9.8 s
Finally, we can substitute this value of t into the equation for height and solve for h:
h = (1/2)gt^2 = (1/2) × 9.8 m/s^2 × (sqrt(19.6h)/9.8 s)^2
h = (1/2) × h
h = 5 meters
Therefore, the body started to fall from a height of 5 meters above the higher point.
why in five glass is not give a vinegar
Answers
While certain types of glass containers may be suitable for short-term storage of vinegar, it is generally recommended to use non-reactive materials, such as plastic or stainless steel, for long-term storage to avoid any potential chemical reactions or corrosion.
Vinegar is an acidic liquid that contains acetic acid. When vinegar comes into contact with certain types of glass, particularly those made of lead or other reactive materials, a chemical reaction can occur. This reaction can lead to the leaching of potentially harmful substances into the vinegar.
Glass containers made from specific types of glass, such as soda-lime glass, are generally safe for storing vinegar.
However, it is important to note that prolonged storage or exposure to vinegar can still cause the glass to corrode over time. This can result in the deterioration of the glass container, potentially leading to breakage or the release of glass fragments.
To avoid any potential issues, it is recommended to use containers made of non-reactive materials, such as food-grade plastic or stainless steel, for long-term storage of vinegar. These materials do not react with the acidic nature of vinegar and do not pose a risk of leaching harmful substances.
Additionally, it is important to store vinegar in a cool, dark place to maintain its quality and prevent spoilage. Exposure to light and heat can degrade the quality of vinegar over time.

Challenge Problem (Extra Credit) A car with bad shocks has a mass of 1500 kg. Before you go for a drive with three of your friends you notice that the car sinks a distance of 6.0 cm when all four of you get in the car. You estimate that the four of you together have a mass of [11] kg. As you are driving down the highway at 65 mph you notice that the car is starting to bounce up and down with large amplitude. You realize that there is a periodic series of small bumps and dips in the road that is driving the bouncing. What is the distance (in meters, to two significant figures) between adjacent bumps on the road, assuming that damping by the shocks is negligible
Answers
Answer:
167.354 m
Explanation:
We are given;
The mass of the car with bad shock;
m = 1500 kg
The distance at which the car sinks; x =
6 cm = 6 × 10^(−2) m
The total mass of 4 people; m_t = 11 kg
The total speed in the highway; V = 65
mph = 29.058 m/s
The spring's constant can be calculated from the formula;
F = Kx
F is also equal to mg.
Thus;
m_t × g = Kx
K = (m_t × g)/x
K = (11 × 9.81)/(6 × 10^(−2))
K = 1798.5 N/m
Mass of car and four people;m_(c+t) = 1500 + 11 = 1511 kg
Thus, the period cam be calculated from the formula;
T = 2π√((m_c+t)/k)
T = 2π√(1511/1798.5)
T = 5.759 s
the distance between adjacent bumps is calculated from;
Velocity = distance/time
Distance = velocity x time
Distance = 29.058 × 5.759
Distance = 167.354 m

Answers
Explanation
Step 1
Diagram:
Step 2
the work done by an object is defined as:
the product of the displacement of an object and the component of the applied force which is in the direction of the object's displacement:
\(Work=force*distance*cos(angle)\)so,let
\(\begin{gathered} displacement\text{ =}3m \\ force=\text{ 150 N} \end{gathered}\)therefore,l to reduce the amount of force needed , we need to affect the distnace or the angle
Step 3
let's check every option
A)Make the ramp higher.
as the distnace becomes greater the force must increase too, so this is not the rigth option,in other words , a higher distnace will neeed a stronger force
B)making the ramp longer will make the angle becomes smaller, and this makes the distance becomes greater,
C) when yuo make the ramp shorter ,you will need the same force because the displacementis vertical
when the angle becomes smaller, the work will be the same, but the distnace and force, change, cos
\(\begin{gathered} Work=force*distance*cos(angle) \\ cos\text{ \lparen angle}\Rightarrow0)=1 \\ so,\text{ } \end{gathered}\)when the angle goes to 0° degrees the required force becomes smaller, so
the answer is
b. Make the ramp longer.
D)finally, if yuo lift the object witouth the ramp ( vertically) , the distnace becomes smaller, ( only 3 m),but the force is the total weigth of the object ( 300 N)

Question 16. The girl in the picture is using an ore to push the water backwards. At the same time the canoe is moving forward within the same amount of force. Which of Newton’s Laws would explain why for every action there is an opposition and equal reaction?
Question 62. Label the following image correctly?
Answers
The girl in the picture is using an ore to push the water backwards. At the same time the canoe is moving forward with the same amount of force. Newton's Third Law would explain why for every action there is an opposite and equal reaction. Hence correct option A, (Newton's Third Law.)
Every action has an equal and opposite response, according to Newton's Third Law of Motion. In the example, the girl applies an action force to the water when she pushes it backward with the ore. Newton's Third Law states that the girl and the canoe are both subject to an equal and opposite reaction force from the water.
The girl and the canoe thus encounter a backward reaction force from the water, which causes the canoe to advance. The action force is what the girl with the ore is doing, and the reaction force is what the water is doing to the girl and the canoe. The Third Law of Newton applies to this occurrence.

Explanation:
It's correct on Edge
The first version of a product, which is built and tested during the third stage of technological design, is called a prototype
What are the stages of technological design?There are mainly five stages of the technological design
Identifying the issue that needs to be solved is the first step in every problem-solving process.
The second stage is to imagine; during this phase, a designer would generate several concepts and conduct research on potential creations. They must pick a handful of their greatest concepts and then narrow it down to the best.
The third stage plans the imaging stage's selected product. In this process, the product is designed and drawn in order to be made into a model or prototype while taking into account the limitations that must be overcome.
The fourth step entails assessing, testing, and revising the final product. By creating a model or prototype of their product, the designer may decide what they like and what they could modify. This is found through product testing. If changes are necessary, the designer will go through the process again until they are happy with the outcome.
The fifth step is to share your solution. You present your solution to get feedback, exchange ideas with others, and improve your product. After you've gone through the design process a few times, you might decide to reveal your response to a larger audience in later phases. Similar modifications are made to homework by World of Inquiry students before they deliver it during an excursion.

The first law of thermodynamics
2.
The second law of thermodynamics
3.
The third law of thermodynamics
4.
It is allowed
Answers
The scenario described violates option 2. the second law of thermodynamics.
The second law of thermodynamics states that in any energy transfer or transformation, the total entropy of an isolated system always increases or remains constant, but it never decreases. Entropy can be thought of as a measure of the disorder or randomness in a system.
In the given scenario, the machine is claimed to create 1000J of heat energy from only 100J of electrical energy. Heat energy is a form of random molecular motion, and the conversion of electrical energy to heat involves an increase in entropy. According to the second law, energy transfers or transformations must always lead to an overall increase in entropy.
However, in this scenario, the machine appears to violate the second law by creating a significant amount of heat energy from a relatively small amount of electrical energy. This would imply a decrease in entropy, which contradicts the fundamental principle of the second law.
In reality, no machine can achieve 100% efficiency, meaning it cannot convert all the input energy into the desired output energy without any energy losses. Some energy will always be lost as waste heat due to inefficiencies in the conversion process. This waste heat contributes to the increase in entropy.

Answers
The magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹ (Option E).
The electric flux through a surface is given by the product of the electric field strength and the area of the surface projected perpendicular to the electric field.
In this case, the electric field strength is 18 N C⁻¹, and the area of the sheet projected perpendicular to the electric field is 0.450 m²
(since the normal to the sheet makes an angle of 60° with the electric field). Multiplying these values gives the electric flux:
Electric flux = Electric field strength × Area
Electric flux = 18 N C⁻¹ × 0.450 m²
Electric flux = 8.1 N m² C⁻¹
In summary, the magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹. This value is obtained by multiplying the given electric field strength by the projected area of the sheet perpendicular to the electric field.
The angle of 60° is taken into account to determine the effective area for calculating the flux.(Option E).

This is the third time Demario has been so worried about other personal matters that he hasn’t done quite as well on the quizzes as he might have otherwise. What has Demario upset is the fact that the professor leaves the room while the students take the quiz, and over half the class is taking the opportunity to cheat. Demario knows personally several of the other students in the class, and some of the ones Demario hangout with are among those who are cheating. Demario knows that a failure to speak to the professor about the cheating will result in his own grade being lower, since the school grades on the curve system. But if Demario does say something to the professor he will be doing his friends and the others a great harm, since cheating is taken very seriously at the school and can lead to expulsion. If Demario doesn’t “turn in” the classmates, the only other alternative is he will get a worse grade than he deserves. He will also be labled as a snitch among is peers and a cheater at the school, either of which Demario has never done. Further, if the professor somehow discovers that Demario is hiding the cheating of others, Demario will be considered an accessory to the cheating, and may be reprimanded for not turning others in, since the school operates on an honor system.
