ANSWER:

Your QUESTION is INCOMPLETE PLEASE SEND the comlete question

The degree of convergence or divergence of light rays by the lens is called it's power.

or,

The reciprocal of focal LENGTH is known as power.

It's SI unit is Dioptre.

By using formula of power,

★

where, it is multiplied by 100 to convert in cm.

Now focal length = 40 cm

Nature:- It is convergence lens because it's power is positive or CONVEX lens.

Now focal length = -20 cm

Nature :- It is a divergence or CONCAVE lens because it's power is in NEGATIVE.

Answer:

An ODOMETER or odograph is an INSTRUMENT used for measuring the DISTANCE travelled by a VEHICLE, such as a bicycle or car.

y=(x3 - 3X + 3) ( X2 + 2x -1)

x5 - 6X - 3

Answer:

Explanation:

Object distance given is 15cm which is (U).

Object length(o) = 4 cm.

Focal length(f) = 5 cm.

Thus, magnification(m) is object distance / IMAGE distance

m=i/o.

Or, we can SAY -

1/v - 1/u=1/f

1/v - 1/15 = 1/5

So, 1/v = 1/5 + 1/15

        1/v = 4/15

          v= 15/4 cm which is the POSITION of the image from the                 convex lense.

Thus, magnification is (f-v)/f=m

                                 =(5-15/4)/5=m

                                 = 5/20=m

                                  m=1/4.

Now, m=i/o for all lenses  

=1/4=image / 4

So, image distance is 1 cm.

Nature of the image will be larger and inverted.

Explanation:

The scientists propose that space is 3D because of a THERMODYNAMIC quantity called the Helmholtz FREE energy density. In a UNIVERSE filled with RADIATION, this density can be thought of as a kind of pressure on all of space, which depends on the universe's temperature and its number of SPATIAL dimensions.

Being log-periodic, the antenna's main characteristics (RADIATION pattern, gain, driving point impedance) are ALMOST constant over its entire frequency range, with the match to a 300 Ω feed line ACHIEVING a standing wave ratio of better than 2:1 over that range.

Answer:

Ohm's LAW stated that voltage or POTENTIAL difference between two points is directly PROPORTIONAL to the CURRENT or electricity passing through the resistance, and inversely proportional to the resistance of the circuit. The FORMULA for Ohm's law is V=I/R.

Explanation:

MANY musical instruments CONSIST of an air column enclosed inside of a hollow metal TUBE. Though the metal tube may be more than a meter in length, it is often curved upon itself ONE or more times in order to conserve space. If the end of the tube is uncovered such that the air at the end of the tube can freely vibrate when the sound WAVE reaches it, then the end is referred to as an open end. If both ends of the tube are uncovered or open, the musical instrument is said to contain an open-end air column. A variety of instruments operate on the basis of open-end air columns; examples include the flute and the recorder. Even some organ pipes serve as open-end air columns.

EXPLANATION:

ENERGY = FORCE × Distance So, if UNIT of Force and unit of length is DOUBLED then unit of energy will be quadrapuled

Explanation:

To measure the shape of the signal, FS will need to be divided by 10 INSTEAD of 2. For example, a signal with frequency 50 Hz, there will need to be at LEAST 0.02(1/50) SECONDS of data for a full period of the signal. At a sampling rate of 100 Hz for a frequency measurement, N will be 5000.

1. The problem statement, all variables and given/known data what happens to wavelength if temperature increases? 2. RELEVANT equations V= lambda * frequency 3. The attempt at a solution I'm guessing since no change to frequency is STATED?.. and I know that the speed of sound increases as temperature increase. The wavelength would have to increase in order to balance the equation V= lambda * frequency? But I'm not sure if it's CORRECT or why and if frequency would be affected by temperature or not.. I can't find a straight ANSWER or explanation on google so here I am.

IT'S IS THE REPRESENTATION OF QUANTITIES WITH RESPECT TO LENGTH AND TIME

Explanation:

.velocity is speed in a PARTICULAR direction.

.velocity is a VECTOR quantity.

.S.I unit of velocity is m/s in a particular direction.

. velocity=displacement/time

. acceleration is RATE of CHANGE in speed.

. acceleration is represented by m/s^2.

Answer:

Prism in Physics is defined as a transparent, polished flat optical element that reflects light. These can be made from any transparent material with WAVELENGTHS that they are designed for. Most commonly USED material are glass, fluorite and plastic.

Prisms called dispersive prism are used to break the light into its spectral colors. Other uses of prisms are to split light into its components with polarisation or to reflect light. Following are the types of prisms:

Dispersive prisms: These are used to break the light into their constituent spectral colors. A triangular prism, amici prism grism are few examples of the dispersive prism.

Reflective prisms: These are used to reflect light in order to invert, rotate, deviate or displace the light beam. Pentaprism, dove prism, retroreflector prism are some of the examples of reflective prisms.

POLARISING prisms: These are used to split the beam of light by varying the polarisation. Nicol prism, Glan-Taylor prism are some the examples of polarising prisms.

Beam-splitting prisms: These are used to split beams into two or more beams. Beam splitter cube and dichroic prism are the examples of the beam-splitting prism.

Deflecting prisms: These are used to deflect the beam of light at a fixed angle. Wedge prism is the EXAMPLE of deflecting prism.

Derivation of prism formula

μ=sinisinr (by Snell’s law)

δ=i1−r1+i2−r2… (eq.1)

δ=i1+i2−(r1+r2)

∠ALO+∠AMO=2rt∠s (from quadrilateral and ∠ALO=∠AMO=90°)

∠LAM+∠LOM=2rt∠s (sum of four ∠s of a quadrilateral = 4 rt∠s) (eq.2)

∠r1+∠r2+∠LOM=2rt∠s (eq.3)

∠LAM=∠r1+∠r2 (comparing eq.2 and eq.3)

A=∠r1+∠r2

δ=i1+i2−A (substituting A in eq.1)

i1+i2=A+δ

∠i1=∠i2

∠r1=∠r2=∠r

∠ALM=∠LMA=90∘−∠r

Thus, AL = LM and LM ∥ BC

∠A=∠r1+∠r2

A=2r (since, ∠r1=∠r2=∠r)

r=A2

i1+i2=A+δ

i1+i1=A+δm

2i1=A+δm

i1=A+δm2

∴μ=sinA+δm2sinA2

Thus, above is the prism formula

Question:

Find the total resistance of the circuit and the CURRENT drawn in the arm CD?

Answer:

In the arm CE

2 OHM and 4 ohm resistance are in series,

Therefore total resistance in arm CE is 2 + 4 = 6 ohms.

Arm Ce and arm AB are parallel

Arm Ce and arm AB are parallel so total resistance of the circuit is :

1/Rtotal = 1/6 + 1/6

1/Rtotal = 1/6 + 1/6 = 2/6

R/total = 6/2= 3 ohms

Answer:

Natural sources of light INCLUDE the sun, stars, fire, and electricity in storms. There are even some animals and plants that can CREATE their own light, such as fireflies, jellyfish, and mushrooms. This is called BIOLUMINESCENCE. Artificial light is created by humans.

Explanation:

Flashlights, table lamps, neon SIGNS, and televisions are some sources of artificial light. Most of the LIGHTS that are man-made need an energy source, such as electricity or batteries, to produce light.

Answer:

Convex mirror are used for rear view in vehicles not CONCAVE mirror.

Convex mirror shows objects SMALLER and can cover a wider area than concave mirror allowing driver to look more than he WOULD be if he were using concave mirror. SInce objects in convex mirror LOOKS smaller so the rear view mirror MAKERS write this line on rear view mirrors i.e.

"Objects are closer than they appear."
