• Two bodies 'A' and 'B' have VELOCITIES in the

ratio of 2 : 1.

• Mass of body A is half of the mass of body 'B'.

To calculate :

• The ratio of kinetic energies of A and B.

Calculation :

As velocities of 'A' and 'B' are in the ratio of 2 : 1. So,

Let ,

• Velocity of body A = 2v

• Velocity of body B = 1v or v

Also, let US assume ,

• Mass of body B = m

So, as per the given question mass of body A is half of the mass of body 'B'.

Mass of Body A =

Now, let's calculate the ratio of the kinetic energies of 'A' and 'B' .

Kinetic Energy of Body A :

We know that,

• K.E = Kinetic Energy

• m = mass

• v = velocity

Here,

✰ Mass of A =

✰ Velocity of A = 2v

Substituting values,

Kinetic Energy of Body B :

We know that,

• K.E = Kinetic Energy

• m = mass

• v = velocity

Here,

✰ Mass of B = m

✰ Velocity of B = v

Substituting values,

Calculating Ratio :

Therefore, the kinetic energies of 'A' and 'B' are in

the ratio of 2 : 1.

ong>Explanation:

EXAMPLES of Newton's THIRD law of motion are ubiquitous in everyday life. For EXAMPLE, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite REACTION force that PROPELS you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.

This lecture note is based on the textbook # 1. Electric MACHINERY - A.E. Fitzgerald, Charles Kingsley, Jr., Stephen D. Umans- 6th edition- Mc Graw Hill series in Electrical Engineering. Power and Energy

The objective of this course is to study the DEVICES used in the interconversion of electric and mechanical energy, with emphasis placed on electromagnetic rotating machinery.

The transformer, although not an electromechanical-energy-conversion device, is an important component of the overall energy-conversion process.

Practically all transformers and electric machinery use ferro-magnetic material for shaping and directing the magnetic fields that acts as the medium for transferring and converting energy. Permanent-magnet materials are also widely used.

The ability to analyze and describe systems containing magnetic materials is essential for DESIGNING and understanding electromechanical-energy-conversion devices.

ong>Given info : the INITIAL amount of CARBON 14 is 100g and the amount of carbon 14 dropped to 1 g after decay process and the half line of carbon 14 is 5,730 yrs.

To find : The TIME taken to COMPLETE this decay process is ...

solution : using half life equation, T½ = ln2/k

where k is decay constant

given half life, T½ = 5730 yrs

so 5730 = ln2/k

⇒k = ln2/5730 ....(1)

initial amount of carbon 14, N₀ = 100g

final amount of it, N = 1G

using decay equation, N = N₀e^(-kt)

⇒1 = 100 × e^(-kt)

⇒ln(1/100) = -kt

⇒ln(100) = kt

⇒t = ln(100)/{ln2/5730} = 5730 × ln(100)/ln2

= 38069.3 yrs

Therefore the time taken to complete the decay process is 38069.3 yrs

ong>ANSWER:

Principle of calorimetry - law

The principle of calorimetry (or principle of mixtures) states that for an insulated system, HEAT energy LOST by the hot body is EQUAL to the heat energy GAINED by the cold body.

Average velocity = 20 m/s for time t .

TOTAL time = t + 2t seconds => 3t seconds

Average speed = 10 m/s

To find -

=> Velocity for next 2t seconds so that average speed is 10 m/s .

Concepts/Formulae Used -

»

»

Note -

=> We have assumed distance and displacement to be the same here since it is rectilinear motion in a straight line.

=> So, we can interchangeably refer to the ratio as speed or velocity .

LET's Solve -

» Values that we already have -

=> We already know that the total time is 3t seconds.

=> We also know that the Average speed is 10 m/s .

» For total distance -

=> Total distance = (distance COVERED in time t) + (distance covered in time 2t) .

• For distance in time t -

   => Average velocity = 20 m/s

  => Time = t seconds

  =>

   => Distance = 20t metres

• For distance in time 2t -

    => Let velocity for this be V m/s .

    => Time = 2t seconds

   =>

   => Distance = 2t * v metres

Total distance = 20t + 2tv

                        => 2t(10+v) metres

» Finding the value of 'v' -

Total time = 3t seconds

Total distance = 2t(10 + v) metres

Average speed = 10 m/s

=>

=> (t is cancelled)

=>

=> 30 = 20 + 2v

=> 30-20 = 2v

=> 10 = 2v

=> 2v = 10

=> v = 10/2

=> v = 5 m/s

Answer -

=> The velocity of the PARTICLE for the next 2t seconds should be 5 m/s .
