Answer:
you need to include the units for both axis to be able to answer this
Explanation:
average speed in uniform motion is the slope anywhere on the line but you could always pick 2 points and do it that way and speed is just rise over run
or y2-y1/x2-x1
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
the second bit i think they are looking for this calculation y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y axis (the vertical one that has no units
Then use that formula for the last question and put in the x value of 10 and complete the formula to find out what y is

The graph shows the motion of a lift starting at rest and initially moving upwards: What is the acceleration of the lift between 0 and A?
Answers
Answer:
0.67 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 m/s
Final velocity (v) = 2 m/s
Time (t) = 3 secs
Acceleration (a) =?
Acceleration can be defined as the rate of change of velocity with time. It can be represented mathematically as:
Acceleration = change in velocity /time.
a = (v – u) /t
With the above formula, we can calculate the acceleration of the lift as shown below:
Initial velocity (u) = 0 m/s
Final velocity (v) = 2 m/s
Time (t) = 3 secs
Acceleration (a) =?
a = (v – u) /t
a = (2 – 0) /3
a = 2/3
a = 0.67 m/s²
Thus, the acceleration of the lift between 0 and A is 0.67 m/s².

C. Obesity and diabetes
D. Obesity and heft
Answers
Answer: A. Overweight and obesity
Explanation:
Overweight and obesity are labeled for ranges of weight that are greater than what is generally considered healthy for a given height. Hence, option A is correct.
What are Overweight and obesity?Overweight and obesity are calculated by Body Mass Index (BMI). BMI is a person's weight in kilograms divided by the square of height in meters. The healthy adult human BMI ranges from 18.5 to 25.
If BMI is less than 18.5, it falls within the underweight range. If the BMI ranges from 25.0 to 29.9, it falls within the overweight range. If the BMI is greater than 30, it comes under the obesity range. A high BMI indicates high fatness.
Obesity and overweight are determined as an abnormal growth or excessive fat accumulation in the healthy range. It is caused by an energy imbalance between calories consumed and calories expended.
Obesity and Being overweight can cause certain diseases and health issues. It increases the risk of high blood pressure, heart disease, diabetes, and stroke.
It is important to maintain a healthy range BMI. Obesity and overweight are reduced by making the choice of healthier foods and regular physical activities like yoga and exercise.

Lack of investigation – we jurors were told over and over not to investigate the situation ourselves. We were to make our decision only on the basis of the evidence presented to us. I can tell you in the case I was on there were at least two whopping big questions hanging over the case that nearly every juror in the room identified as very important but not addressed by either lawyer. Either one of them (whether the defendant’s schedule allowed time to drink before being stopped in the car, whether a particular medical condition could affect breathalyzer tests) could have changed the outcome. We could have answered one of these with 10 minutes on google and the other with some very simple subpoena of records. But we couldn’t use any of this. Scientists obviously are the opposite – if they need more information, they are expected to go get it before making an opinion.
Reliance on personal testimony – although science and trials share a focus on evidence, trials recognize testimony of individual people under oath as a major form of evidence. They certainly acknowledge the possibility of lying and explicitly instruct jurors to decide what testimony they believe. My case was unusual in that there was so much video footage, but still a majority of the case came down to testimony by the police officers, and most cases even a few years ago would have had only testimony. Science on the other hand, doesn’t accept testimony. Or does it? What else is the methods and results section of a paper? I’m on the fence whether science is so different on this one.

O Children of servants were included in the law as recipients of said education.
Children were to be sent to designated schoolmasters for their learning.
Answers
Answer:
What was not required by the Massachusetts Education law of 1642 is;
Children were to be sent to designated schoolmaster for their learning
Explanation:
The Law of 1642 required that parents and master see to it that their children knew the principles of religion and the capital laws of the commonwealth.
The important aspects of the 1642 Law includes;
1) The responsibility for the basic education and literacy of a child are those of the parents and masters of child apprentices
2) Reading and writing competency of all children and servants are a requirement
3) It is the duty of the government, where a parent or master are unable to meet their tutoring responsibility, to see that a child is placed where the basic educational requirement will be met.
The role of a schoolmaster or the setting of a formal school were yet to be formed as at that time.
Answer:
The correct answer is Children were to be sent to designated schoolmasters for their learning
The responsibility of educating children was on parents and apprenticeship masters, not on designated teachers or schoolmasters. However, the law did allow the government to step in if the supervising adults failed in their responsibilities.

When it is 21 m above the ground, a package is released from the balloon. For
how long is it in the air?
Answers
Answer:
The time spent in air by the package is 1.5 s
Explanation:
Given;
speed of the balloon, v = 7.0 m/s
distance traveled by the balloon, d = 21 m
The time spent by the object in the air is give by;
d = vt + ¹/₂gt²
21 = 7t + ¹/₂(9.8)(t²)
21 = 7t + 4.9t²
4.9t² + 7t -21 = 0
solve this quadratic expression, and the value of t will be
t = 1.5 s
Therefore, the time spent in air by the package is 1.5 s

a 50-kg object moving at 12 m / s has a momentum of 600 kg m / s what is the mass of an object moving at 4 m/s has the same momentum
Answers
Explanation:
p=mv
600kgms-1=m × 4ms-1
m=600kgms-1/4ms-1
m=150kg
The mass of the object which has momentum of 600kgm/s with the velocity of 4m/s is 150kg.
What is Momentum?Momentum is the product of the mass and velocity of the object. Momentum is the quantity of motion which is made up of the amount of matter moved and the velocity at which it moves. Momentum is a vector quantity because it has both the magnitude and direction. The SI unit of momentum is kg.m/s (kilogram meter per second).
p = m × v
p = momentum of the object,
m = mass of the object,
v = velocity of the object
600kgm/s = m × 4m/s
m = 600/ 4
m = 150kg
Therefore, the mass of the object will be 150kg.

What do the planets have in common and how are they different?
Answers
Answer:
They vary quite a lot, yet there are some similarities
Explanation:
With Mercury, you have a hot and barren expanse of rock
With Venus, you also have a fairly hot and barren expanse of rock, with a molten core
With Earth, you have a warm/cool variant with water and a full atmosphere
With Mars, you have a colder and barren expanse of valleys and rock, with a rather paste-like ground
With Jupiter, we have our first gas giant, covered in clouds with a thick atmosphere
With Saturn, it is yet another gas giant, with rings of gas and rock and a dense core of metals, such as iron and nickel
With Uranus, it is also rather gas-full with a fair amount of water and methane, which results in its bluish color (an ice giant)
And finally with Neptune, it is the other ice giant, consisting of water, methane, and ammonia
So there are some similarities (gases, water, land formations, etc.) and some differences (rings, temperature, structure, etc.). Our planets are very unique to one another and continue to engage and surprise us.
A car accelerates from rest at 7.2 m/s 2 . How much time does it need to attain a speed of 4 m/s? Answer in units of s.
Answers
Answer:
The time is 0.6 sec.
Explanation:
Given that,
Acceleration of car = 7.2 m/s²
Speed = 4 m/s
We need to calculate the time
Using equation of motion
[tex]v=u+at[/tex]
Where, u = initial velocity
v = final velocity
a = acceleration
t = time
Put the value in the equation
[tex]4=0+7.2\times t[/tex]
[tex]t=\dfrac{4}{7.2}[/tex]
[tex]t=0.6\ sec[/tex]
Hence, The time is 0.6 sec.
A 3.00 kg mass is traveling at an initial speed of 25.0 m/s. What is the
magnitude of the force required to bring the mass to rest in a distance of 62.5m?
Answers
Answer:
The magnitude of the force required to bring the mass to rest is 15 N.
Explanation:
Given;
mass, m = 3 .00 kg
initial speed of the mass, u = 25 m/s
distance traveled by the mass, d = 62.5 m
The acceleration of the mass is given as;
v² = u² + 2ad
at the maximum distance of 62.5 m, the final velocity of the mass = 0
0 = u² + 2ad
-2ad = u²
-a = u²/2d
-a = (25)² / (2 x 62.5)
-a = 5
a = -5 m/s²
the magnitude of the acceleration = 5 m/s²
Apply Newton's second law of motion;
F = ma
F = 3 x 5
F = 15 N
Therefore, the magnitude of the force required to bring the mass to rest is 15 N.
Which of these objects could be falling with constant acceleration?
Answers
Answer:
1 and 2
Explanation:
If an object has constant acceleration, it's displacement at time t is:
Δx = v₀ t + ½ at²
For object 1:
0.44 = (0) (0.3) + ½ a (0.3)²
a = 9.78
3.14 = (0) (0.8) + ½ a (0.8)²
a = 9.81
So object 1's acceleration is approximately constant.
For object 2:
0.06 = (0) (0.3) + ½ a (0.3)²
a = 1.33
3.09 = (0) (2.1) + ½ a (2.1)²
a = 1.40
So object 2's acceleration is approximately constant.
For object 3:
0.44 = (0) (0.3) + ½ a (0.3)²
a = 9.78
3.09 = (0) (2.1) + ½ a (2.1)²
a = 1.40
So object 3's acceleration is not constant.
