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.

In many locations, old abandoned stone quarries have become filled with water once excavating has been completed. While standing on a 10.0 m high quarry wall, Clarence tosses a piece of granite into the water below. If Clarence throws the rock horizontally with a velocity of 3.0 m/s how far out from the edge of the cliff will it hit the water?
Answer:
Explanation:
Let us calculate the time of flight first using the formula;
Velocity = Displacement/Time
Time = Displacement/speed
Time = 10.0/3
Time = 3.33secs
Next is to calculate how far out from the edge of the cliff it will hit the water. To get that, we will use the equation of motion;
S= ut+1/2gt²
u is the initial velocity = 0m/s
g is the acceleration due to gravity = 9.81m/s
S = 0 + 1/2(9.81)(3.33)²
S = 4.905*3.33*3.33
S = 54.39m
Hence it will hit the water at 54.39m from the edge of the cliff
Answer:
It will hit the water at [tex]4.28m[/tex] off the cliffExplanation:
Applying kinematic relations along vertical direction
[tex]y = V_0t + \frac{1}{2}a_yt^2[/tex]
where,
[tex]a_y = g[/tex]
therefore,
[tex]y = 0 + \frac{1}{2}gt^2[/tex]
The time taken
[tex]t = \sqrt{\frac{2y}{g}}\\\\t = \sqrt{\frac{2*10}{9.8}}\\\\t = 1.428s[/tex]
The horizontal distance
[tex]x = V_yt\\\\x = 3*1.428\\\\x = 4.28m\\\\[/tex]

what are muons in cosmology
Answer:
Explanation:
Muons in the atmosphere, a component of cosmic rays. Atmospheric muons are an essential component of cosmic ray showers. When a high energy primary particle coming from space collides with a nucleus of the upper atmosphere, it generates a spray of particles which later interact in their turn.

1. what organisms are shown?
2. Do they look the same?
3. Do the pictures show the same species?
4. How are they similar?
5. How are they different?
Answer:
u need it now?
Explanation:
I'll answer it
Based on the diagram above, the organisms that are shown are elephants.
What is a species?A species simply refers to a biological classification of related organisms that have the same (similar) characteristics and they are capable of mating (breeding) with one another in a cycle (different seasons).
Based on the diagram above, we can logically deduce that the organisms shown are species of elephants and they look similar due to the following points:
They both have a single tail.They both have ears.They both have four legs.They both have tusk.However, an obvious difference between them is the number of tusk.

average velocity of the race car? (1 pt)
a. Zero
b. 100 m/s
C. 200 m/s
d. None of the above
3. In problem two. What would be the average speed? (2 pts)
1
Answer:
100m/s
Explanation:
velocity = displacement/time
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.
What is Average Velocity?Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.
It is expressed as;
Velocity = displacement / time
It can also be expressed as;
Velocity = circumference / time = 2πr / t
Given the data in the question;
Radius of the track r = 500mTime elapsed t = 50sAverage velocity V = ?To determine the average velocity, we substitute our values into the expression above.
V = 2πr / t
V = ( 2 × 3.14 × 500m ) / 50s
V = 3140m / 50s
V = 62.8m/s
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.

How long would it take you too run the 100m sprint if from rest you accelerate at 2m/s/s for the whole race?
Answer:
10 s
Explanation:
Given:
Δx = 100 m
v₀ = 0 m/s
a = 2 m/s²
Find: t
Δx = v₀ t + ½ at²
100 m = (0 m/s) t + ½ (2 m/s²) t²

The electric motor of a model train accelerates the train from rest to 0.620 m/s in 21ms. The total mass of the train is 825 g. find the average power delivered to the train during its acceleration.
Explanation:
Average power = change in energy / change in time
P = ΔE / Δt
P = (½ mv²) / t
P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)
P = 7.55 Watts
A moving object is in equilibrium. Which best describes the motion of the object if no forces change?
O It will change directions.
O It will slow down and stop.
O It will maintain its state of motion.
O It will speed up and then slow down.
Answer:
It will maintain its state of motion
Explanation:
The object would maintain its state of motion.
What does it mean when an object is in equilibrium?If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.

a. How can a spinning ball have more lift than one that is not spinning?
Answer:
It is spinning, making the ball a little more airborn than the one that isn't spinning
Answer:
A spinning ball creates a Centrifugal Force because it is given the "energy" so to speak to spin. A ball that is not moving does not need any external energy to keep it still or, in other terms, at rest.

Answer:
7.5 seconds
Explanation:
Given that a dog starts at the origin and runs forward at 6 m/s for 1.5 s
From speed formula
Speed = distance/time
Substitute speed and time into the formula
6 = distance/1.5
Distance = 6 × 1.5 = 9 m
and then turns around to fetch the ball by
running backward at 7 m/s for 3 s. If the dog runs.
Calculate the distance covered
Distance = 7 × 3 = 21 m
This means that the dog ran beyond the original position.
The elapsed distance = 21 - 9 = 12m
back to the origin at 4 m/s, by covering distance 12 m
Calculate the time.
Speed = distance/time
Time = 12/4 = 3s
The time elapsed between the start and when he returns with the ball will be:
T = 1.5 + 3 × 3
T = 7.5 seconds

PLS HELP. A flatbed car of a train moves 8 m/s to the east. A jogger runs along to top the flatbed car (which is not very safe) with a velocity of 6 m/s to the west. How fast is the jogger moving?
Answer:
2 m/s
Explanation: Given that a flatbed car of a train moves 8 m/s to the east. A jogger runs along to top the flatbed car (which is not very safe) with a velocity of 6 m/s to the west.
Since the jogger is moving in an opposite direction to the direction of the train, and velocity is the distance covered in a specific direction, the jogger will be moving at a velocity relative to the velocity of the train.
Velocity = (8 - 6) m/s
Velocity = 2 m/s
Therefore, the jogger will be moving at the speed of 2 m/s

Multiply field strength (N/kg) by mass (kg) to get weight (N)
At the start, the car is carrying
4.7 kg * (9.8 N/kg) = 46.06 N
of fuel.
At the end, it is carrying
3.0 kg * (9.8 N/kg) = 29.4 N.
Assuming the car remains completely intact, its weight was reduced by
46.06 N - 29.4 N = 16.66 N.
