Answer:
i dont really understand but when you accelerate you move faster. So i guess the skateboarder is moving fast forward
Answer: 1 : an observable fact or event. 2a : an object or aspect known through the senses rather than by thought or intuition. b : a fact or event of scientific interest susceptible of scientific description and explanation. More from Merriam-Webster on phenomenon.

Incomplete question: "A signal of 20.7 mV is measured at a distance of 29 mm and 15.8 mV is measured at 32.5 mm. Correct the data for background and normalize the data to the maximum value. What is the normalized corrected value at 32.5 mm?"
The normalized corrected value at 32.5 mm is 0.1638
Explanation:
The corrected light measurement at 29 mm is equal to:
20.7 - 5.1 = 15.6 mV
The corrected light measurement at 32.5 mm is equal to:
15.6 - 5.1 = 10.5 mV
To normalize the data to its maximum value means that the maximum value must be calculated and the data must be scaled using that value, as in this case the maximum value is 15.6 mm, then the normalized corrected value at 32.5 mm is equal to:
10.5 * 15.6 = 163.8 = 0.1638
Answer:
Explanation:
given
initial velocity u = 4.45m/s
Height = 0.6m
g = 9.8m/s²
Required
final velocity v
Using the equation of motion;
v² = u²-2gH (upward motion of the fish makes g to be negative)
v² = 4.45²-2(9.8)(0.6)
v² = 19.8025-11.76
v² = 8.0425
v = 2.84 m/s
Hence the speed of the fish as it passes a point 0.6 m above the water is 2.84m/s
To get the time, we will use the formula
v = u - gt
2.84 = 4.45 - 9.8t
2.84-4.45 = -9.8t
-1.61 = -9.8t
t = 1.61/9.8
t = 0.164secs
Hence the time taken is 0.164secs
Answer:
A motion diagram represents the motion of an object by displaying its location at various equally spaced times on the same diagram. Motion diagrams are a pictorial description of an object's motion. They show an object's position and velocity initially and present several spots in the center of the diagram.
