Rules for drawing ray diagrams for spherical mirror

Answer» DEAR MATE HERE IS UR ANSHWER


Once these incident RAYS strike the mirror, reflect them according to the two rules of REFLECTION for concave mirrors. The ray that passes through the focal point on the way to mirror will reflect and TRAVEL parallel to the principal axis. Use a straight edge to accuratelydraw its path

Is it possible for a particle to have negative kinetic energy in a barrier?

Answer»

No NEVER...KINETIC Energy can never be negaive...

As K.E =
\frac{1}{2} m {v}^{2}
Here m = mass of a particle...which is a scalar quantity and we dont have negative mass...

v = velocity of a particle , THOUGH velocity is a vector quantity so it can be negative...But we have square of velocity which makes velocity always POSITIVE....(square of any number whether a negative or positive always a positive)
So K.E cannot be negative...Atmost it can be zero only if velocity of a particle is zero or particle is at rest..

Role of integrator and clock bistable circuit in adaptive delta modulation

Answer»

A modulation (DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance. DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples are ENCODED into n-bit data streams. In delta modulation, the transmitted data are reduced to a 1-bit data stream. Its main features are:

The analog signal is approximated with a series of segments.Each segment of the approximated signal is compared of successive bits is DETERMINED by this comparison.Only the change of information is sent, that is, only an increase or decrease of the signal amplitude from the previous sample is sent whereas a no-change condition causes the modulated signal to remain at the same 0 or 1 state of the previous sample.

To achieve HIGH signal-to-noise ratio, delta modulation must use oversampling techniques, that is, the analog signal is sampled at a rate several TIMES higher than the Nyquist rate.

Derived forms of delta modulation are continuously VARIABLE slope delta modulation, delta-sigma modulation, and differential modulation. Differential pulse-code modulation is the superset of DM..

Can anyone tell me how to make a prism (rainbow) on a surface with water and torch? No stupid answers.

Answer»

When light goes through a glass of water – it also splits into a rainbow.

To GET ready – take a piece of paper and CUT a slot into the middle of it. Tape this onto the SIDE of a smooth/clear drinking glass so that the sun’s rays can PASS through the opening onto the SURFACE of the water in the glass.

You will NEED to do this on a very sunny day (or try a darkened room with a strong direct light source.)

Make sure that the glass of water is VERY FULL. Place the glass on a white floor or white piece of paper, making sure the sun’s rays are shining through the slot in your paper and hitting the surface of the water.

You should see a mini-rainbow appear below the glass!

The average value of rotational kinetic energy of 1 mole of Oxygen gas at temperature t will be

Answer»

O₂ is a DIATOMIC molecule . Hence , there are five DEGREE of freedom for 1 MOLE of O₂ gas .In which 3 translational and 2 rotational .
∴ degree of freedom for 1 mole of O₂ gas , f = 2 [ for rotational motion ]
We know,
Average Rotational Kinetic energy = \bold{\frac{f}{2}<klux>RT</klux>}
Here f is degree of freedom for rotational motion.
∴ average Rotational Kinetic energy = 2/2 RT = RT

Moment of intertia of rod hinged at end = (1/3)Ml2
Moment of intertia of disc = (1/2)mR2 + ml2

3. The attempt at a solution
Why does the answer disregard the partmoment of intertia of the disc (1/2)mR2that is SPINNING on its own axis, and only taking into account the ml2?

Positive deviation raoult's law change in entropy

Answer»

Raoult's law (/ˈrɑːuːlz/ law) is a law of thermodynamics established by FRENCH CHEMIST François-Marie Raoult in 1887. [1] It STATES that the partial vapor pressure of each COMPONENT of an ideal mixture of liquids is equal to the vapour pressure of the pure component multiplied by its mole fraction in the mixture. In other words it is stated as the relative lowering of vapour pressure of a dilute solution containing NONVOLATILE solute is equal to the mole fraction of solute in the solution.

Introduction to Maximum Power Transfer THEOREM

Very often we come across various real time circuits that WORKS based on maximum power transfer theorem. For effective way of connecting source to load, an impedance matching transformer is used. In case of transmission lines, the DISTORTION and REFLECTIONS are avoided by making source and load impedances to be matched to the characteristic impedance of the line

Find the initial velocity of a car if it can be a stop in 10 second by applying brakes which provide it a retardation of 2.5m/s².

Answer» U = ?
V = 0
t = 10s
a = -2.5 m/s²

v = u +at
⇒ 0 = u + (-2.5)×10
⇒ 0 = u - 25
⇒ u = 25 m/s

Initial VELOCITY was 25 m/s
