This type of energy can be transferred in three different ways: 1) direction contact through collisions (also called conduction)

, 2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection), and 3) by waves traveling with or without a medium (also called radiation)
this type of energy is often found in things like batteries or food


this is radiant energy from the sun; it's the only kind of energy we can see with our eyes


this has to do with the speed of an object and how much mass it has; basically how the object is moving


this is energy that is transferred by the movement of electrons through a conductor: the electrons create a current.


this can be either kinetic or potential and has to do with the energy of position and motion of an object


this is the energy found in the nucleus of an atom


this is the term used when energy changes from one form to another


this type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band


this type of energy travels through vibrations on waves

<h2><u>Answer: </u></h2>

Energy is the ability of matter to produce work in the form of movement, light, heat, among others.

It should be noted that <u>energy is not created or destroyed, it is transformed</u>. This is a universal law, known as the Law of conservation of energy which  is also the first principle of Thermodynamics.

Taking this into account, let’s match each of the types of energy given in the questions with its respective definitions and meanings:

<h2>6.  Thermal energy </h2>

This type of energy can be transferred in three different ways: 1) direction contact through collisions (also called conduction), 2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection), and 3) by waves traveling with or without a medium (also called radiation)

<h2>8. Chemical energy </h2>

this type of energy is often found in things like batteries or food

<h2>5. light energy </h2>

this is radiant energy from the sun; it's the only kind of energy we can see with our eyes

<h2>2. kinetic energy </h2>

this has to do with the speed of an object and how much mass it has; basically how the object is moving

<h2>4. electrical energy </h2>

this is energy that is transferred by the movement of electrons through a conductor: the electrons create a current.

<h2>1. mechanical energy </h2>

this can be either kinetic or potential and has to do with the energy of position and motion of an object


<h2>9. nuclear energy </h2>

this is the energy found in the nucleus of an atom

<h2>10. energy conversions </h2>

this is the term used when energy changes from one form to another

<h2>3. potential energy </h2>

this type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band

<h2>7. sound energy </h2>

this type of energy travels through vibrations on waves

Bas_tet [7]
The reason why there is no energy shortage nor will there ever be is because energy is being preserved and conserved and only changes form. It never gets lost or increased.

Use your knowledge of waves to explain why echoes occur. Use your explanation to devise a system to measure distances to objects
german

Explanation:

Echoes occur due to the reflection of sound from any obstacle, but not all the reflected sound waves lead to the phenomenon of echo. For the echo to be heard it actually depends upon the human perception as well, human ears can encounter the difference between the sound wave directly form the source and the reflected sound waves only if there is a minimum time gap of one-tenth of a second. For this time gap in the atmosphere at normal temperature and pressure the obstacle must be at least 7 meters away from the sound source.

Two coconuts fall freely from rest at the same time, one from a tree twice as high as the other. If the coconut from the shorter
valentinak56 [21]

Wee can use here kinematics

as we know that

y = v*t + \frac{1}{2} at^2

for shorter tree we know that

y = 0 + \frac{1}{2}*9.8 * 2^2

y = 19.6 meter

now since we know that other tree is twice high

So height of other tree is y = 39.2 m

now again by above equation

y = v*t + \frac{1}{2} at^2

39.2 = 0 + \frac{1}{2}*9.8 * t^2

t = 2.83 s

so the time taken is 2.83 s

The force needed to keep a car from skidding on a curve varies inversely as the radius of the curve and jointly as the weight of
motikmotik

Explanation:

It is given that, the force needed to keep a car from skidding on a curve varies inversely as the radius of the curve and jointly as the weight of the car and the square of the car's speed such that,

F\propto \dfrac{mgv^2}{r}

F=\dfrac{kmgv^2}{r}

mg is the weight of the car

r is the radius of the curve

v is the speed of the car

Case 1.

F = 640 pounds

Weight of the car, W = mg = 2600 pound

Radius of the curve, r = 650 ft

Speed of the car, v = 40 mph

640=\dfrac{k(2600)(40)^2}{650}

k = 0.1

Case 2.

Radius of the curve, r = 750 ft

Speed of the car, v = 30 mph

F=\dfrac{0.1\times 2600\times (30)^2}{750}

F = 312 N

Hence, this is the required solution.
