Ghosts are the souls of people who have died cannot be tested experimentally.
An experiment is a technique used in science to create a discovery, test a theory, or show a known truth. because owing to a lack of technology, we might not be able to analyze souls.Any procedure where measurements are taken and tests are run to support or disprove a hypothesis is referred to as a scientific experiment.The scientific experiment is a component of the scientific method as a whole. This process is a series of sequential processes used to learn new information about any subject.The steps are: making a discovery. posing a query and developing a theory. scientific tests to validate the theory and gather data Analyzing the findings and making judgments presenting the findingsTo know more about experiment visit : https://brainly.com/question/9199868

Suppose a particular spectral line has a wavelength of 500 nm in the lab. If you look at the spectrum of star A, you see this line at 480 nm. Star B exhibits this line at 510 nm, and the line is measured to be at 530 nm in star C. Which of the following statements is true?
a. Star A is moving the fastest of the three stars.
b. Star A is the only star moving away from us, star B and star C are both moving towards us (with star C moving towards us the fastest)
c. Star C is moving away from us faster than star B, star A is moving towards us.
A car is initially traveling at an unknown velocity. It accelerates constantly
for 5.0 seconds of elapsed time at a rate of 3.0 m/s² to reach a velocity of
30 m/s. What was the initial velocity of the car?
(A) 1.0 m/s
(B) 5.0 m/s
(C) 10 m/s
(D) 15 m/s
Answer: A
Explanation: No, we put the values S is 200 m and acceleration a is four m per second squared, So this gives us time to equal to 10 seconds
I hope its correct!

Felix steals second base running at a speed 4.2 m/s. He slides into second base at a speed of
The resultant displacement such that Felix steals second base running at a speed 4.2 m/s and slides into second base at a speed of 5.8 m/s is 10 meters.
What is average velocity?Average velocity is a physical quantity which refers to the average of the velocity it takes to compete certain displacement.
It is calculated by adding two velocities and dividing by net time taken.
What is displacement?Displacement is a physical quantity which refers to the shortest possible distance between two points. Displacement drawn is generally a straight line until space curvature starts.
Given:
Speed in first base = 4.2 m/s
Speed in second base = 5.8 m/s
Time taken for first base = 0.5 seconds
Time taken for second base = 1.5 seconds
Average velocity = (4.2+5.8)/2
Average velocity = 5 m/s
Total time taken = 2 seconds
Average displacement = average velocity × total time taken
Average displacement = 5 × 2
Average displacement = 10 meter
Therefore, resultant displacement such that Felix steals second base running at a speed 4.2 m/s and slides into second base at a speed of 5.8 m/s is 10 meter.

you notice another ant beginning to walk along a meter stick. curious, you take out a stopwatch and determine the ant’s position on the meter stick. you record the following data: {(0.0 s, 0.0 m), (1.0 s, 0.12 m), (2.0 s, 0.24 m), (3.0 s, 0.36 m), (4.0 s, 0.48 m)}. determine the ant’s speed from the slope of the distance vs. time graph.
The speed of Ant is 0.12 m / s .
The given data is for Uniform Motion .
Ant ' s speed can be calculated as follows :
Speed = Distance / Time
v = s / t
s ₁ = 0.12 m
t ₁ = 1.0 sec
v ₁ = 0.12 / 1.0
v ₁ = 0.12 m / s
s ₂ = 0.24
t ₂ = 2.0 sec
v ₂ = 0.24 / 2.0
= 0.12 m / s
So , the speed of Ant is 0.12 m / s .
