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)

Two seventh grade students are studying how sound waves are transferring energy. They hold a large pot near the side of a cut of water and bang the pot with a wooden spoon. The sound waves make waves in the glass of water. How would the students increase the amplitude of the waves in the glass of water?
Question 2 options:
Hit the pot faster at a higher frequency
Hit the pot softer with less energy
Hit the pot faster at a higher frequency
Hit the pot harder with more energy
Answers
Answer:
The Answer You Are Looking For Is D) Hit the pot harder with more energy.
Explanation:
The amplitude of a the sound waves can be increased with frequency and hitting the pot harder with more energy will increase the amplitude of sound waves in the glass of water.
What are sound waves?Sound waves are mechanical waves transferring energy through a medium. They are longitudinal mechanical waves, where, the direction of oscillation of particles is in the direction of waves.
The frequency of a wave is the number of wave cycles obtained per unit time. Frequency is directly proportional to the amplitude and energy of the wave but inversely proportional to wavelength and density of the medium through which it travels.
Glass is a denser material and thus frequency of waves through it will be less. Hence by increasing the energy of hitting the frequency and thus the amplitude of sound waves in glass can be increased. Thus option d is correct.

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 ??.
Answers
Answer:
It'll take the student 8 hours.
Explanation:
All you need to do is divide 400 by 50 which is 8. To check this answer multiply 50 x 8 and it'll also equal 400.

Resonance
Answers
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.

b. left, right
c. bottom, top
d. top, bottom

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
Answers
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.
