This can be either kinetic or potential and has to do with the energy of position and motion of an energy- This is related to mechanical energy.It is so because mechanical energy is the sum total of kinetic and potential energy.

This is radiant energy from the sun;it is the only kind of energy we can see with our eyes-It is related to light energy which consists of white light along with its seven colors and these are also electromagnetic radiations.

This is the energy that is transferred by the movement of electrons through a conductor;the electrons create a current-This is related to electric energy.

This type of energy is often found in things like batteries or food-This is related to chemical energy .It is chemical energy which is converted to electrical energy in battery.

This type of energy travels through vibrations on waves-This is related to sound energy which travels in a medium in the form of compressions and rarefactions.

This type of energy is found in the nucleus of an atom-This is related to nuclear energy.For instance the energy produced during nuclear fusion and fission from unstable nuclei.

This is the term used when one type of energy changes from one form to another-This is related to energy conversions.

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 is related to potential energy .It is the energy gained by a body due to its position or change in configurations.

This type of energy can be transferred in three different ways i.e conduction,convection and radiation-We know that heat is transferred in three different ways mentioned above and heat is nothing else than transferred  thermal energy.Hence, it is related to thermal energy.

This has to do with the speed of an object and how much mass it has;basically how the how the object is moving-This is related to kinetic energy which is the energy gained by a body due to its motion.

Mathematically it is written as

                                      kinetic\ energy =\frac{1}{2} mass*[velocity]^2

Tyrone, an 85-kg teenager, runs off the end of a horizontal pier and lands on a free-floating 130-kg raft that was initially at
Ghella [55]

Answer:u=4.04 m/s

Explanation:

Given

Mass m=85 kg

mass of Raft M=130 kg

velocity of raft and man  v=1.6 m/s

Let initial speed of Tyrone is u

Conserving Momentum as there is no external Force

mu=(M+m)v

85\times u=(85+130)\cdot 1.6

u=\frac{215}{85}\cdot 1.6

u=2.529\cdot 1.6=4.04 m/s

Aluminum has a density of
agasfer [191]

<h3><u>Volume is 0.1848 m³</u></h3><h3 />

Explanation:

<h2>Given:</h2>

m = 49.9 kg

ρ = 270 kg/m³

<h2>Required:</h2>

volume

<h2>Equation:</h2>

ρ \:= \:\frac{m}{v}

where: ρ - density

m - mass

v - volume

<h2>Solution:</h2>

Substitute the value of ρ and m

ρ \:= \:\frac{m}{v}

270\: kg/m³\:= \:\frac{49.9\:kg}{v}

(v)\:270\: kg/m³\:= \:49.9\:kg

v\:= \:\frac{49.9\:kg}{270\: kg/m³}

v\:= \:0.1848\:m³

<h2>Final Answer:</h2><h3><u>Volume is 0.1848 m³</u></h3>

it is possible that the acceleration and velocity are perpendicular to each other? explain with example​
shusha [124]

Answer: Ok so We already know that velocity is on the x-axis.

Since acceleration = Force / Mass

Here the Force is downward due to the gravitational pull or we can say it is along y-axis.

Since acceleration is directly proportional to force, so acceleration is also along y-axis. This means that velocity & acceleration are perpendicular to each other.

Example:

Let us assume that an aeroplane is flying parallel to the horizontal plane. The aeroplane will experience the acceleration in several directions. One of them here is the gravitational pull which is perpendicular to the the apparent velocity. So the net velocity & its direction will depend upon the vector sum total of all the forces/acceleration acting on it. Also because of this gravitational pull the aeroplane rotates along with the earth, which is a proof that the force/g experienced by it does not go waste.
