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

Dolphins communicate using compression waves (longitudinal waves). Some of the sounds dolphins make are outside the range of hum
lana66690 [7]

Answer: send the message underwater because a more dense medium would make the sound travel faster.

Explanation:

Dolphins communicate using compression waves - longitudinal waves. Longitudinal waves requires a medium to travel. A longitudinal wave transfers energy by the vibration of medium particles in the direction of the wave motion. Compression are the regions where density of the medium is higher and rarefaction is a low density region.

A longitudinal wave travels faster in a denser medium. It has maximum speed in solid and minimum in gas. Thus, to transfer message quickly to dolphin B., dolphin A should send the message underwater and not in air. This is because water has higher density than air. Molecules collide more quickly in water than in air and it takes less time for signal to travel.

Two waiters are trying to get through a single door of a kitchen. One pushes on one side of a door 0.567 m from the hinge with a
NISA [10]

Answer:

275.5 N

Explanation:

F_{1} = Force on one side of the door by first waiter = 257 N

F_{2} = Force on other side of the door by second waiter

r_{1} = distance of first force by first waiter from hinge = 0.567 m

r_{2} = distance of second force by second waiter from hinge = 0.529 m

Since the door does not move. hence the door is in equilibrium

Using equilibrium of torque by force applied by each waiter

r_{1} F_{1} = r_{2} F_{2} \\(0.567) (257) = (0.529) F_{2}\\F_{2} = 275.5 N

A heavy meterstick has a mass of 1 kg. When the meterstick is thrown like a spear past you, you measure its momentum to be 2mv.
CaHeK987 [17]

Answer:

Its length is measured to be 0.5 m

Explanation:

From theory of relativity (mass variation), we know that:

m = mo/√(1-v²/c²)

Where, m = relative mass

and, mo = rest mass

The momentum of stick while moving, will be:

P = mv

but, it is given in the form of rest mass as:

P = 2(mo)v

thus, by comparison;

2(mo)v = mv

using value of m from theory of relativity;

2(mo)v = (mo)v/√(1-v²/c²)

√(1-v²/c²) = 1/2     ______ eqn(1)

Now, for relativistic length (L), we have the formula from same theory of relativity;

L = (Lo)√(1-v²/c²)

The rest length (Lo) of meter stick is 1 m, and the remaining term on right side √(1-v²/c²), known as Lorentz Factor, can be given by eqn (1), as equal to 1/2.

Thus,

L = (1 m)(1/2)

<u>L = 0.5 m</u>

what is the difference between stirring hot soup with a wooden spoon and a metal spoon? what physical property is being observed
AnnyKZ [126]

Wooden spoons don't quickly heat to hot temperatures not nearly as fast as metal does. Metal conducts heat faster than wood — if the head of the spoon is in a hot liquid, the handle will get hot faster if it's made out of a metal.
