Energy can be transferred from one storage mechanism to another.
How energy is converted from one form to other
Explanation:
Energy can be converted from one form to another. Examples: Gasoline (chemical) is put into our cars, and with the help of electrical energy from a battery, provides mechanical (kinetic) energy. ... Similarly, purchased electricity goes into an electric bulb and is converted to visible light and heat energy.
Answer:
Explanation:
Energy transformation is when energy changes from one form to another. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation. For example, Electricity goes into an electric bulb and is converted to visible light and heat energy.

what happens to the mechanical energy of an apple as it falls from a tree?
Answer:
When the apple falls from the tree, it has some gravitational potential energy due to its height. Now, When it starts falling, the Gravitation Potential energy will starts converting into the Kinetic Energy. When the apple is about to strikes the ground, the Gravitational Potential energy have been converted into the Kinetic Energy.
Explanation:
The potential energy will be low when its kinetic energy is high and vice versa. But the mechanical energy remains conserved.
What is mechanical energy?Mechanical energy can be explained as the sum of kinetic energy and potential energy that can be used to do work. Mechanical energy can be described as the energy of a body due to its motion or position.
The total mechanical energy of a physical system is conserved as the energy can not be created or destroyed. The mechanical energy of a physical system can only be transformed from one form to another when the forces acting work are conservative in nature.
Each force is related to potential energy form and the energy changes between different kinds of potential energy and kinetic energy but the total energy remains constant.
The mechanical energy of the apple remains conserved. As the apple falls its potential energy is converted into kinetic energy.

the path of least resistance.
b.
a path toward the north pole.
c.
a path toward the south pole.
d.
the path that leads through insulators.
Answer:
A. The path of least resistance.
Explanation:
ur welcome again ;)
An electric current will always follow the path of least resistance. So, the right option is a.
In inverse relation to the resistance of the pathways, electric current follows every available paths.
The voltage and resistance of the path in the electric circuit affect the amount of electric current that flows through the circuit.
The quantity of electric current flowing through the circuit is inversely proportional to the resistance in the circuit.
Assuming a fixed voltage, the current increases with decreasing resistance. The current decreases in accordance to the level of increasing resistance.

Green light (520 nm) enters glass with n = 1.52. What is the wavelength of light that enters the glass?
Answer:
answer=1.97×10^8
Explanation:
will u mark me brainliest?
Green light (520 nm) enters glass with n = 1.52, the wavelength of light that enters the glass is 520 nm.
To find the wavelength of light that enters the glass, we can use Snell's Law, which relates the angles and indices of refraction for light passing through a boundary between two mediums:
n₁ × sin(θ₁) = n₂ × sin(θ₂)
In this scenario, we can assume that the angle of incidence is zero degrees (the light is entering the glass perpendicular to the surface). Therefore, sin(θ₁) becomes sin(0) which is 0.
Using Snell's Law, we have:
n₁ × sin(θ₁) = n₂ × sin(θ₂)
1 × 0 = 1.52 × sin(θ₂)
The wavelength of light that enters the glass remains the same as the initial wavelength in air, which is 520 nm (nanometers).
Thus, the wavelength of light that enters the glass is 520 nm.

Radio waves pass through us easily every day with no bad effects. Gamma Rays will kill you in large doses. What is the difference between these two forms of energy?
Answer:
gamma rays are super compact
Explanation:
as you move up the electromagnetic spectrum the wave lengths get shorter and shorter (higher and higher energy) gammas being the highest on the spectrum
Radio waves pass through us easily every day with no bad effects. Gamma Rays will kill you in large doses. the difference between these two forms of waves are in their energy.
What is wave ?Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.
Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.
There are two types of the wave longitudinal wave and transverse wave.
The energy of the electromagnetic photon is given by frequency times plank's constant. Hence energy is directly proportional to the requency. The frequency of the radio waves is far smaller than the gamma rays hence it has low energy. this is the difference, which leads gammas rays injurious to heath.

what is the relationship between harmonics and resonance frequency in a piano
There is direct relationship between harmonics and resonance frequency.
A harmonic is a wave with a frequency that is a positive integer multiple of the frequency of the original wave whereas, resonance frequency is the frequency at which the oscillation reaches to its maximum point. The lowest resonant frequency is known as the fundamental, while on the other hand, the higher resonant frequencies are called overtones. All resonant frequencies are multiples of the fundamental, and are called harmonics. So we can conclude that there is a direct relationship between harmonics and resonance frequency.Learn more about harmonic here: https://brainly.com/question/17315536

Qs 5 pleaseeee help!!!
Answer:
Ok, first is important that you understand how the heat radiation works.
All the objects that have some heat energy in them, radiate some of that energy in the form of electromagnetic waves.
Particularly, the Sun radiates a lot of energy (at the point that if you step under the sunlight, you can feel on your skin the heat that comes from the sun, this is due to radiation).
Now, suppose that you have a thin coat of water over you, then the material that gets impacted by that radiation will be the water and not you, and then the energy is dissipated (some of the energy goes to your body and some go to the air)
This is one way in which spraying water over themselves helps the elephants to keep them cool.
Another way in which heat can be transferred is by conduction.
When you have a hot object and a cool object, and you put them together (so the objects touch each other), the heat will flow from the hotter object to the cooler object until both objects have the same temperature.
Then if the elephant body temperature is larger than the temperature of the water that the elephant sprays over his body, when the water touches the body some of the heat in the elephant body will be transferred to the coat of water, and in this way, the temperature of the elephant's body decreases.
These are the two ways we wanted to find.

The diagram below shows a light ray striking a plane mirror surface at an angle of 40° to the normal. Which of the following diagrams shows the ray that is reflected from the plane mirror surface?
Answer:
3rd diagram
Explanation:
From the laws of reflection, we understood that the angle of incidence in equal to the angle of reflection.
For example, if a ray of light strikes a mirror at 60°, it reflected at the same angle (i.e 60°)
Considering the diagram given in the question above,
The ray of light strikes the mirror at 40°. Therefore, the light will be reflected with the same angle (i.e 40°)
Thus, the 3rd diagram gives the correct answer to the question.
Joni plays a scale on her clarinet. As she plays from low notes to high notes, what happens to the sound waves that the clarinet creates?
Answer:
The answer is "The frequency of the sound waves increases".
Explanation:
Its most oscillating their frequency waves, therefore higher the vibration we hear. However you see, sound frequency is determined through the oscillation of electrical signals while moving to our ears, which implies that perhaps the audio medium, which usually is air, makes a distinction between compression to spreading. It's the end of the communication as the frequency rises.
