Answer:

the study of <u>MOTION</u> is called kinematics

Explanation:

Kinematics is the study of motion and its various parameters. Here we study about the acceleration velocity and displacement and their relations.

If an object is moving with some speed then its final speed and the displacement of object with time is analysis or study of motion.

So here in this all analysis we need not to discuss about the cause of motion we need to discuss only about the motion and its various parameters.

So here the correct answer would be

the study of <u>MOTION</u> is called kinematics

Which describes the two parts of a measurement? a unit and a symbol a conversion factor and a number a symbol and a conversion f

wariber [46]

<h2>Right answer: a number and a unit</h2>

The measurement consists in <em>comparing a selected pattern with the object or phenomenon whose physical magnitude is going to be measured, to find out how many times the pattern is contained in that magnitude.</em> That is, it is about identifying or quantifying a particular characteristic or aspect of a particular object or construct.

Now, a well done measurement has two parts:

-The number gives us information about the quantity of the measurement, or in other words, the magnitude of the measurement and its precision.

-The units gives us information about the property that is being measured. This is quite important, because a measurement or result with no units is useless.

Note the units may be expressed with letter or symbols, depending on what we are measuring.

The Millennium Falcon was constructed 43.6 m long. a) How fast is it traveling past Luke when he measures its length to be 30.1

Zinaida [17]

Answer:

a)0.5564c

b)43.6 m

Explanation:

Given proper length of falcrum L₀= 43.6 m

improper length L=30.1 m (when viewed from moving frame)

we know that $L=L_{0}\sqrt{1-\frac{v^2}{c^2}}$

$30.1=43.6\sqrt{1-\frac{v^2}{c^2}$

⇒ $\{1-\frac{v^2}{c^2}}$ = $\frac{30.1}{43.6}$

${1-\frac{v^2}{c^2}}=0.6904$

$\frac{v^2}{c^2}=0.3096$

$v^{2}=3096c^{2}$

v=0.5564c

this is the required speed of falcon when it passes luke

b). Since Han solo is on the Falcon its reference frame will be falcon itself hence there wont be any change in the length of Falcon that its length will be

43.6 m

A petrol engine that transforms 1000J of chemical potential energy into 300J of kinetic energy, and 700J into wasted heat and so

sergey [27]

Answer:

Efficiency = 30% = 0.3

Explanation:

The general formula for efficiency of a device is given as:

Efficiency = (Desired Output/ Input) * 100%

Here, in our case, we have a petrol engine as a device. So, we analyze it for the efficiency calculations. Here, we have:

Chemical Potential Energy = 1000 J

Kinetic Energy = 300 J

Heat and Sound Energy = 700 J

Now, we know that the desired output of a car or the purpose of a car is to provide Kinetic energy, while all other forms of energy such as heat and sound energies are produced as waste. And the chemical energy is provided to car as input, in form of fuel. Therefore,

Input = Chemical Potential Energy = 1000 J

Desired Output = Kinetic Energy = 300 J

Therefore,

Efficiency = (300 J/1000 J) * 100%

<u>Efficiency = 30% = 0.3</u>
