While no energy can escape from beyond the event horizon AROUND the black hole, energy is released from the material as it FALLS in. Accretion onto a black hole is the most efficient process for emitting energy from MATTER in the Universe, RELEASING up to 40% of the restmass energy of the material FALLING in.

It's NATURAL COLOUR is BLACK so at which EVER colour it is ,it will be black...

A LEAF appears green in DAYLIGHT because it absorbs all WAVELENGTHS of visible light spectrum except the green colour, and THEREFORE it appears green as they reflect it. But when solely red light is given to the leaf, it will absorb the red light and therefore appears as black. As we know when all the wavelengths of the spectrum are absorbed, the subjected object appears black; and if they appear WHITE, that means the object reflects the incident light.

Because it does not has its own LIGHT.It SHINES DUE to the light of the SUN.

According to hinsberg UNCERTAINTY principle the POSITION and momentum of an electron cannot be a determined SIMULTANEOUSLY. Because ELECTRONS don't have a definite position and DIRECTION .

Hey mate!

as u know
R =RHO l/A

multiplying both NUMERATOR and denominator by A you will GET..

R =rho V/A^2

where,

V = volume (GIVEN 1cc)

A =area

rho =RA^2/V

1mm =0.1cm....

diameter=0.32mm =0.16 ×10^-cm..

Rho =2.46(0.16×0.16×10^-2 ×3.14)^2

rho =1.58 × 10^-6 ohm-cm

Because Z>1 ,here z=compressibility factor. That’s why at higher pressure and LOWER TEMPERATURE gas can be compressed

TWO ESSENTIAL CONDITIONS TO BE FULFILLED FOR OSCILLATION ARE:-

✓ repeated after definite time

✓ to and fro about a point.

Example:-MOTION of simple PENDULUM for large displacement.

a moving car can be stopped easily because the FRICTION is more high in the road and the ship can't stop immediately BECOZ the WATER has a very very LOW firction



hope it will help
take care Budd...

There are more VELOCITY and SPEED

6billions NUMBER of PHOTONS will be SOURCE of 1000W

The OBJECT FLOATS on the SURFACE

Hi mates here is your answer
Specular reflection is also know as REGULAR reflection. it is the MIRROR lie reflection of waves, such as LIGHT from a surface

A leaf appears green in daylight because it absorbs all WAVELENGTHS of visible light spectrum except the green colour, and therefore it appears green as they REFLECT it. But when solely RED light is given to the leaf, it will absorb the red light and therefore appears as black.

a=slope ab

a=bf/FA

a=bt-ft/ot   [CAUSE ot//to fa]

a=v-oa/t

a=v-u/t

at=v-u        [CROSS MULTIPLICATION]

v-u=at

v=u+at  

it COULD be false

as mass=weight/g

m=9.8/9.8

mass=1 kg

now force=mass*acc

40=1*a

acceleration=40m/s2

The first law is simply a conservation of energy equation: The INTERNAL energy has the symbol U. Q is POSITIVE if heat is ADDED to the system, and negative if heat is REMOVED; W is positive if workis done by the system, and negative ifwork is done on the system.

The SHEEP dollly..................

This example is an approximation. We are supposed to find the average distance between the molecules in air, and the first approximation is to assume that air only CONSISTS of N2 (I know it is only about 78% N2, but this is only an approximation).

The atomic NUMBER of N is 14, which gives the MOLECULAR mass

2⋅14⋅U≈46⋅10−27kg

where u is representing the atomic mass unit: u≈1.66⋅10−27kg.

The density of air is given as: ρair≈1.3kg/m3.

The volume occupied by 1 molecule can THEREFORE be written as

Vmolecule=mN2ρair≈35⋅10−27m3.

The DIMENSION FORMULA of Capacitance in TERMS of (M L T I) is :

C=Q/V

=Q*Q/W

=Q²/W

=i²t²/W

[C]=[M⁻¹L⁻²T²][I²T²]

=[M⁻¹L⁻²T⁴I²]

THE FIRST LAB IS HAVING HIGHER RESISTANCE THAN THE SECOND ONE.

Iron filings attracted to a horseshoemagnet SHOW the MAGNETIC field. ... It refers to physical phenomena arising from the force caused by magnets, objects that PRODUCE fields that ATTRACTOR repel other objects..

Electric power is the rate, PER unit time, at which ELECTRICAL energy is transferred by an electric circuit. The SI unit of power is the WATT, one joule per second. Electric power is usually PRODUCED by electric generators, but can also be supplied by sources such as electric batteries.
