Using the picture above, which ball has the greatest potential energy?
Ball 1 has the greatest amount of potential energy inside it because it has the maximum height among all the balls shown in the graph.
What is Potential energy?Potential energy is the stored energy which depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched due to external force.
Potential energy is not affected by the environment outside of the object or its system, such as the air or height. On the other hand, kinetic energy is the energy of an object or a system's particles in motion.
The potential energy of an object depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity and h is the height in meters.
The object 1 has maximum height hence, it has greatest potential energy.

Explain how sound travels from your vocal cords to your friend’s ear when you talk
Answer:
Your vocal cords vibrate and then travel through the air to your friends ear. ... loudness is a humans perception of sound intensity, as intensity of a sound wave increases the loudness of a sound wave increases.
~+lil more info+~
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.

How can humans use their knowledge of changing states of matter to better society? (ex. A human can harness the thermal energy from transitioning water from a liquid state to a gas state.)
Please Hurry This assignment is due tonight.
Write 5 sentences why. Thanks
Answer:
Anything that has mass is made up of matter – an all-encompassing word for atoms and molecules that make up our physical world. We describe this matter as existing in states (sometimes referred to as phases). Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates

Hey I'm working on this test right now, did you ever get the answers?
what is an element that needs to lose or gain
4 valence electrons in order to become
stable?
Answer:
Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure. In fact, if they are going to form ions, Group 14 elements form positive ions. Carbon and silicon form covalent bonds. Carbon's millions of organic compounds are all based on shared electrons in covalent bonds.

what is the two kinds of solids in amorphous
Solids can be classified into two types: crystalline and amorphous. Crystalline solids are the most common type of solid. They are characterized by a regular crystalline organization of atoms that confer a long-range order. Amorphous, or non-crystalline, solids lack this long-range order.
Hardin electronic corporation is designing a new cell phone, they need a solid material that will insulate the phone and product their users from electric shock. Which material would best fit the needs of Hardin engineers A. A non-metal B. A metalloid C. A metal D. A semiconductor
Answer:
A
Explanation:
The material that would best suit Hardin electronic corporation's need would be a non-metal.
Non-metals are naturally occurring substances or materials that lack the properties of metals. In other words, non-metals are poor conductors of heat and electricity, unlike metals.
Solid non-metals are, therefore, used as insulators in the design of materials. Hence, the best material for Hardin electronic corporation to use that will insulate the phone and protect their users from electric shock would be a non-metal.
The correct option is A.
I NEED HELP :) ty.............
Answer:
The answer to your question is given below
Explanation:
From the question given above, we can see that the wave with a higher frequency has a shorter wavelength while that with a lower frequency has a longer wavelength. This is so because the frequency and wavelength of a wave has inverse relationship. This can further be explained by using the following formula:
Velocity = wavelength x frequency
Divide both side by wavelength
Frequency = Velocity /wavelength
Keeping the velocity constant, we have:
Frequency ∝ 1 / wavelength
From the above illustration, we can see clearly that the frequency and wavelength are in inverse relationship. This implies that the higher the frequency, the shorter the wavelength and the shorter the frequency, the higher the wavelength.

An 80-kg student collides with a padded wall in the gymnasium while moving at 6.0 m/s.
Because he collided with a padded wall instead of a concrete wall, the time of collision was
increased by a factor of 10. What affect does this increase in collision time have upon the
force and the impulse that he experiences? Select two answers.
1. Colliding with the padded wall will make the force 10 times greater.
2. Colliding with the padded wall will make the force 10 times smaller.
Answer:
2. Colliding with the padded wall will make the force 10 times smaller
Explanation:
Impulse is the product of force and time. Its units are those of momentum. Assuming the change in momentum (impulse) remains the same, the increase in time means the force will be decreased by the same factor.
Colliding with the padded wall will make the force 10 times smaller

Question 2 of 25
What is the voltage drop across the 20 resistor?
10.00
120.0 V
20.0 2.
www
30.02
The voltage drop across the 20 Ohm resistor is 40V.
To determine the answer, we need to know about the current flowing through the resistor.
What is the total resistance of the circuit?As the three resistors are connected in series, so the resultant resistance is
10 Ohmv+ 20 Ohm + 30 Ohm = 60 Ohm
What is the current flowing through the resistors?As these resistors are connected in series, so the amount of current flowing through each resistor is equal.According to Ohm's law, current = voltage/resistanceCurrent= 120/60 = 2 A
What is the voltage across the 20 Ohm resistor?According to Ohm's law, voltage across the 20 Ohm resistor
= current×resistance
= 2×20
= 40volt
Thus, we can conclude that the voltage across the 20 Ohm resistor is 40V.

Which statement best describes what was demonstrated about speed and pitch in the "Doppler Effect" lab?
Speed and direction do not affect pitch.
Speed and direction affect pitch.
Direction affects pitch but not speed.
Speed affects pitch but not direction.
Answer:
Speed and direction affect pitch.
Answer:
The correct answer is B. Speed and Direction affect pitch
Explanation:
The Doppler effect, a quantitative analysis that demonstrates how the repetition heard by the stable perceiver depends on whether the perceiver sees the source approach, causes sound and light waves to increase and decrease in frequency due to the proportional motion between the wave source and its receivers. Accordingly, when the wave source is moving, waves are perceived at frequencies that are different from one another.
