Answer: 2m/s
Explanation:
The acceleration of the wake boarder is equal to 2 m/s².
What is acceleration?Acceleration of a body can be described as the change in velocity of a body with respect to time. The acceleration is a vector parameter posses both magnitude and direction. Acceleration is described as as the second derivative of position w.r.t. time and the first derivative of the velocity of an object w.r.t. time.
According to Newton's 2nd law of motion, the force (F) acting is equal to the product of the mass and acceleration (a).
F = ma
or, a = F/m
Therefore, acceleration (a) is inversely proportional to the mass (m).
Given, the force with which the boat pulled wake boarder, F = 124 N
The mass of the wake boarder = 62 Kg
The acceleration of the wake boarder, a = 124/62 = 2 m/s²
Therefore, the acceleration of the wake boarder is 2 m/s².

Define each vocabulary word and use each word in a sentence
Reflection
Refraction
Diffraction
absorption
interference
standing wave
Resonance
Answer:
Reflection:
The phenomenon of a propagating wave (light or sound) being thrown back from a surface
Sentence: Your reflection is what you see in the mirror. Other things that bounce back at you are also reflections — light waves, sound waves, even your thoughts.
Refraction:
Definition: The change in direction of a propagating wave (light or sound) when passing from one medium to another
Sentence: Refraction is the bending of light or sound as it passes through something like a wall (sound) or a window (light).
Diffraction:
Definition: When light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands
Sentence: Diffraction is the process of light bending around an obstacle or spreading out after it moves through a small space. If you study physics, you'll learn about the diffraction of light waves.
Absorption:
Definition: (chemistry) a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid
Sentence: Absorption describes the process of absorbing or soaking up something: Sponges are good at water absorption; dark colors are better for heat absorption.
Interference:
Definition: The act of hindering or obstructing or impeding
Sentence: Interference is something that is in your way. If the sound of your sister's band practicing keeps you from getting your homework done, that’s interference.
Standing wave:
Definition: A wave (as a sound wave in a chamber or an electromagnetic wave in a transmission line) in which the ratio of its instantaneous amplitude at one point to that at any other point does not vary with time
Sentence: A bubble, trapped and held in a fixed position by an acoustic standing wave, begins to move erratically if a threshold wave amplitude is exceeded. The longitudinal standing wave is synchronously forced and resonated while the cross-wave is not resonant and is of higher order in amplitude.
Resonance:
Definition: Having the character of a loud deep sound; the quality of being resonant
Sentence: If you have a loud, deep voice, then your voice has resonance, and if your words are powerful and meaningful, then your words have resonance, too. Something with resonance has a deep tone or a powerful lasting effect.
I hope this helps! :)
How did you figure that out? (think of FORMULA!)
Answer:
the most potential energy would be at the highest point and the least it's at the lowest point so let's say and rollercoaster when it's like moving up its gaining potential energy while it's going down it loses potential energy (sorry if u get it wrong)

1. LAW OF SUPERPOSITION: When observing rock layers, the oldest rocks/fossils can be found at the ______________, while the youngest can be found at the _______________.
a. middle, bottom
b. left, right
c. bottom, top
d. top, bottom
2. Two rock layers contain fossils of similar organisms. What is likely true of these rock layers?
a. They were from different environments.
b. They had advantageous traits.
c. They had analogous structures.
d. They were from the same time period.
ps this is science
Answer:
Q1. Young rocks are found on top, and old layer are found on the bottom.
Q2. Layers of sedimentary rock. Fossil layers are fossils that formed in sedimentary rock. When, over a long time, layers and layers of sediments get deposited on top of each other, the weight of the top layers presses down on the bottom layers, forming them into rock called sedimentary rock
Explanation:
Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.

A student needs to travel a total of 400 miles to reach his vacation destination . if he drives at an average speed of 50 mph how many hours will it take for him to complete the 400 miles ??.
Answer:
It'll take the student 8 hours.
Explanation:
