For writing a scientific lab report, when you write the discussion do you need to include every single result in your data? Or do you just include a summary of your data?
Answer:
include a summary of data
Explanation:
In writing a scientific laboratory report, only the summary of the data is included in the discussion and not the entire result.
The discussion section of a lab report deals with the interpretation and explanation of findings during the course of the experiment in relation to the background information leading to the experiment/research. Hence, only the summary of the data generated is required. The detailed results are usually reported in the result section, not the discussion section.

2. A ball is dropped from a height of 52 m. The ball falls freely and reaches the ground in 75 s. What was the average speed of the ball?
Answer:
v = 0.69 m/s
Explanation:
Given that,
A ball is dropped from a height of 52 m.
The ball reaches the ground in 75 seconds
We need to find the average speed of the ball. The ball will travel a distance of 52 m in 75 s. The average speed of the ball is distance divided by time taken. So,
[tex]v=\dfrac{52\ m}{75\ s}\\\\v=0.69\ m/s[/tex]
Hence, the average speed of the ball is 0.69 m/s.
Difference between si unit and derived unit
Answer:
Derived units are derived from these 7 base units. Derived units are dependent on the base units and are not independent of each other. ... Mass has SI units of kg, distance is measured in m and t has the SI unit of second. Thus, SI unit of force is kg.
Carlos runs with velocity \vec{v}v →= (5.6 m/s, 29o north of east) for 10 minutes. How far to the north of his starting position does Carlos end up? (Give your answer to the nearest meter)
Answer:
1629 metres
Explanation:
Given that Carlos runs with velocity v = (5.6 m/s, 29o north of east) for 10 minutes.
To the north, the velocity will be:
V = 5.6 × sin 29
V = 2.715 m/s
Convert the time to second
Time = 10 × 60 = 600
Using the formula below
Velocity = distance/ time
Substitute all the parameters into the formula
2.715 = distance/600
Distance = 2.715 × 600
distance = 1629 m

A wave has a length of 8 meters and a speed of 32 meters per second. What is the frequency of the wave
Answer:
The frequency of wave is 4 hertz.
Explanation:
Given,
wave length = 8m
speed of sound ( v) = 32 m/s
frequency ( f) = ?
we know,
v = f × lambda
or, 32 = f × 8
or, f = 32/8
or, f = 4 Hertz.

Please help on this physics question
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
What happens to the chemical structure of water when it changes state?

B. Water molecules harden into ice molecules.
C. Water molecules melt into gas molecules.
D. Nothing happens to the chemical structure.
Answer:
c) Water molecules melt into gas molecules.
The chemical structure of water when it changes state - D. Nothing happens to the chemical structure.
Physical state of an object is the condition where substance have different energy content. For instance water is on heating it change into vapor or gaseous phase while cooling (decreasing heat content) causes water to become ice in solid phase. Therefore,
physical states is only in the energy content of the substance.Change in the state or phase of water does not change the chemical property. However, changing phase can alter the speed of the chemical reactions.Thus, the change in physical state do not affect chemical properties, but affects the kinetics of the reactions.

Explanation:
A student walks to the right 25-m along the 800 hall in 15-s. They turn around and walk 15-m to the left in 8.0-s. Calculate the average speed and the average velocity
Answer:
Explanation:
Total distance covered = 25 + 15 = 40 m
Total time = 15 + 8 = 23 s
Average speed = total distance covered / total time
= 40 / 23
= 1.74 m / s
Total displacement = 25 - 15 = 10 m
Total time = 15 + 8 = 23 s
Average velocity = total displacement / total time
= 10 / 23
= .434 m / s to the right .
The average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left).
Given:
Distance to the right = 25 m
Time taken to the right = 15 s
Distance to the left = 15 m
Time is taken to the left = 8.0 s
To calculate the average speed and average velocity, we need to use the following formulas:
Average speed = Total distance traveled ÷ Total time taken
Average velocity = Displacement ÷ Total time taken
Calculate the total distance traveled:
Total distance = Distance to the right + Distance to the left
Total distance = 25 + 15 = 40 m
Calculate the total time taken:
Total time = Time taken to the right + Time taken to the left
Total time = 15 + 8.0 = 23 s
Calculate the average speed:
Average speed = Total distance ÷ Total time
Average speed = 40 ÷ 23 = 1.74 m/s
Calculate the displacement:
Displacement = Final position - Initial position
Displacement = (-15 ) - 25 = -40 m
Calculate the average velocity:
Average velocity = Displacement ÷ Total time
Average velocity = -40 ÷ 23 ≈ -1.74 m/s
So, the average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left). The negative sign in the average velocity indicates that the student's net direction is to the left.

How can positive feedback influence the stability of a system?
A. It can cause the system to remain stable as long as inputs are
constant
B. It can cause the system to oscillate between stability and
instability
c. It can cause instability that eventually results in the system's
destruction
D. It can cause instability by reversing the direction of the system,
The positive feedback influence the stability of a system is: It can cause the system to remain stable as long as inputs are constant. Hence, option (A) is correct.
What is stability ?A body's capacity to return to its initial static equilibrium after being slightly shifted is referred to as stability.
A body in equilibrium doesn't suffer linear acceleration or a turning effect, and unless a force from the outside disturbs it, it will stay in that state forever. (The First Law of Newton)
When tiny, externally induced displacements from an equilibrium result in forces or torques that tend to oppose the displacement and bring the body back to its initial equilibrium, the equilibrium is said to be stable.If even the smallest deviations result in forces or torques that tend to increase the displacement, the equilibrium is said to be unstable.Learn more about stability here:
