What is kelvin scale and celsius scale

Answer»

Explanation:

Celsius is, or relates to, the Celsius temperature scale (previously KNOWN as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as SERVE as unit increment to indicate a temperature interval(a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death.

K = °C + 273.15

°C = K − 273.15

Until 1954, 0 °C on the Celsius scale was defined as the melting point of ice and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalence is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement, defined by two different points: absolute zero, and the TRIPLE point of SPECIALLY prepared water. This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C.

Describe power in long

Answer»

Answer:

Power comes from the Latin word potere, which means "to be able." But things with power are much more than able — they're able to exert a lot of force. "The powers that be" are those who hold authority, and "the power BEHIND the THRONE" refers to the people who exert influence without being formally in charge.Expert Answer. 100% (1 rating) Power is the influence that you have on other people. A person can have influence on others by the virtue of his or her personality traits, knowledge, skills etc. For example a doctor has the power toview the full answer.Power is the amount of work that is done. Power is the product of force APPLIED that displaces an object.......

Example for ideal machine ​

Answer»

Answer:

answer is

Explanation:

Ideal machine. The term ideal machine refers to a hypothetical mechanical system in which ENERGY and power are not lost or dissipated through friction, deformation, wear, or other inefficiencies. ... Mechanical efficiency is the performance of the machine compared to its theoretical maximum as performed by an ideal machine ...Ideal MACHINES have the theoretical maximum performance and THEREFORE are used as a baseline for evaluating the performance of real machine SYSTEMS. A simple machine, such as a lever, pulley, or gear train, is "ideal" if the power input is equal to the power output of the device, which means there are no losses.

There are lots of things that can be eaten and in many ways explain the statement briefly

Answer»

The EXPLANATION of the statement,that there are lots of things that can be eaten and in many ways,is as follows -

• The food MATERIALS are MOSTLY cooked before we eat.

• Now,there are different methods of cooking,like boiling,frying,baking etc.

• So,we can make different TYPES of food from a SINGLE uncooked food material by using different types of cooking methods.

• And,we can also change the secondary ingredients in order to make new dishes with the same food material.

• Even we can do this with the ready to eat food materials also. Example,banana can be simply eaten or can be used to make banana shake.

• In this way,we are able to eat a food material in different ways.

When an electron in Hydrogen atom revolves in stationary orbit, itA) does not radiate light though its velocity changes.B) does not radiate light and velocity remains unchanged.C) radiates light but its velocity is unchanged.D) radiates light with the change of energy.​

Answer»

Hyy Dude

As the ELECTRON, in the Hydrogen ATOM, revolves around the nucleus in a stationary orbit, it means the electrons does not jump from one orbit to another and thus it does not radiate light.

Also the electron moves in a circular orbit, ALTHOUGH magnitude of its VELOCITY remains the same but it continuously changes its direction. Hence we say that the velocity of electron changes when it revolves in a stationary orbit.

Starting from home a person goes to market 2km from home and returned back to a friend's house on same road 500m from the market. It took him 40min to complete the journey. What is speed and velocity? Which one of them is larger value?

Answer»

Velocity = DISPLACEMENT/time

Here, velocity = 1500/40x60     (Since displacement = 2km-500m and 40 minutes = 40x60 seconds)

  1. Therefore, velocity = 0.625 m/s

SPEED = DISTANCE/time

Here, speed = 2500/40x60      (Since distance = 2km+500m and 40 minutes = 40x60 seconds)

    2. Therefore, speed = 1.04 m/s (Approximately)

    3. => Speed is larger than velocity

the numerical ratio of displacement to distance for a moving object. always less than 1 equal to 1 or more than 1 always more than 1​

Answer»

Answer:

Yea, That's Holds True.

Explanation:

Remember, The DISTANCE is always GREATER than or equal to the displacement(when the BODY is in rest or moves in a single STRAIGHT path) but is NEVER lesser than the displacement.

So, \frac{Displacement }{Distance} \leq 1

It is one when the distance is equal to the displacement.

It is lesser than one when the distance is greater than the displacement.

28.

The numerical ratio of displacement to distance for a moving object.always less than 1equal to 1 or more than 1always more than 1equal to 1 or less than 1.​

Answer»

Question - The NUMERICAL ratio of DISPLACEMENT to distance for a moving object is _____________.

Answer -

The numerical ratio of displacement to distance for a moving object is equal to one or less than one.

Explanation -

The displacement for a moving object is always equal to or less than the (actual) distance covered. Therefore, when we take the displacement as the numerator and distance as the DENOMINATOR, the numerator(displacement) is EITHER equal to the denominator(distance) or less than the denominator(distance). We know that WHENEVER the numerator and denominator are same, the ratio is equal to one and whenever the numerator is lesser/smaller than the denominator, the ratio is less than one.

Hence, the ratio of displacement to distance is always either equal to one or less than one.

What is means by corrosion?​

Answer»

Answer:

Corrosion is a chemical reaction that happens on metals due to the attack of acid, water or moisture.

Skme examples are:-

  • The silver articles become black after sometime when exposed to air this is because of the presence of sulphur in air which forms a coating of sulphur SULPHIDE on the article.

  • The copper reacts with moist carbon dioxide in the air and loses its ground SURFACE by gaining a green coat which is BASIC copper carbonate.

  • Wheniron is exposed to moist air for a long time it acquires a coating of brown substance which we normally CALL as rust.

Prevention of corrosion:-

  • Painting
  • Oiling
  • Greasing
  • Galvanising
  • Chrome plating
  • Anodising
  • Making ALLOYS

1. A patient's leg was put into traction, stretching the femur from a length of 0.46 m to 0461 m.The femur has a diameter of 3.05 cm. With the knowledge that bone has a Young's modulus of1.6 10 in tensions, what force was used to stretch the femur?​

Answer»

Thus the AMOUNT of force used to stretch the FEMUR is F = 25, 391 N

Explanation:

F = Y ( Δ L / LO) A

Y = 1.6 x 10^10 Pa

Lo = 0.46 m

Δ L = Lo - L = (0.461 - 0.46 ) =  0.00 1 m

A = πr^2

A = 3.14 x (1.525)^2

A = 7.30 cm^2 = 0.00073 m^2

Now using Young's modulus equation.

F = 1.6 x 10^10 x (0.001 / 0.46 ) x 0.00073

F = 25, 391 N

Thus the amount of force used to stretch the femur is F = 25, 391 N

two infinite parallel lines of charge are shown in the figure below ,and are separated by 5 cm.Their uniform linear charge densities are (λ1) +2.0x10^-6 C/m and (λ2)=-3.0x10^-6 C/m.Find the net electric field at point that is 1.0 cm to the left of (λ1).Express your answer in unit vector notation

Answer»

Given :

The separation between the two infinite PARALLEL lines of charge =5 cm

The uniform linear charge density of first line is :

\lambda_1 = +2.0 \times 10^{-6} \frac{C}{m}

The uniform linear charge density of 2nd line is :

\lambda_2 =-3.0 \times 10^{-6} \frac{C}{m}

To Find :

The net electric FIELD at a point 1 cm to the left of \lambda_1= ?

SOLUTION :

The net electric field at the point 1 cm left of \lambda_1 will be = E_1 - E_2

Here E_1  is electric field at this point due to \lambda_1

Here E_2  is electric field at this point due to \lambda_2

Since , the electric field due to an infinitely LONG line charge is =\frac{k\lambda }{r}

Here k is electrostatic constant , \lambda is linear charge density and r is distance

of point .

So, E_{net} = \frac{k\lambda_1}{r_1} -\frac{k\lambda_2}{r_2}

Or, E_{net}  = k(\frac{\ambda_1}{r_1}- \frac{\lambda_2}{r_2})

              =9 \times 10^9(\frac{2\times 10^{-6}}{5+1} -\frac{3\times 10^{-6}}{1})

              = 9 \times 10^9 \times 10^{-6} (\frac{2}{6}- \frac{3}{1})

              = 9 \times 10^3 (\frac{1-9}{3})

              = 3 \times 10^3 \times (-8)

              = -24 \times 10^3 \frac{N}{C}

Hence ,the electric at the required point is towards right and its magnitude is -24 \times 10^3 \frac{N}{C} .
