Hey buddy....
As U know speed of light is 3*10^8m/s
so for 1 MIN distance covered by light is 6*10^9m/m
and for an hour...36*10^10m/hr
and for a day 864*10^10 m/day
so for a month 2592*10^11 meter/month
and for a year 31104*10^11 meter/ year
so according to ur question u R asking that light took 20 years to cover that particular distance so need to multiply is by 20 nd i.e., 20*31104*10^11=62208*10^12 m
that is the distance in meters if u want in kilometers then just simply convert it...
Hope it will help u.. :)

Role of Friction in Starting Rolling Motion, Friction. When a force is applied to a ball or WHEEL, it will START rolling, provided there is a resistive force PREVENTING the wheel from simply sliding along the other surface. ... The RESISTANCE of STATIC friction causes the rolling motion.

The term angular frequency VECTOR is sometimes used as a synonym for the vector quantity angular velocity. ... ω is the angular frequency or angularspeed (measured in radians per second), T is the period (measured in seconds), f is the ordinary frequency (measured in hertz) (sometimes symbolised with ν).


In physics, angular frequency ω (ALSO referred to by the TERMS angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance) is a scalar measure of rotation rate. It refers to the angular displacement per unit time (e.g., in rotation) or the rate of change of the phase of a sinusoidal waveform (e.g., in oscillations and waves), or as the rate of change of the ARGUMENT of the sine function.

Angular frequency (or angular speed) is the magnitude of the vector quantity angular velocity. The term angular frequency vector {\displaystyle {\vec {\omega }}}is sometimes used as a synonym for the vector quantity angular velocity.[1]

One revolution is equal to 2π radians, hence[1][2]

{\displaystyle \omega ={{2\pi } \over T}={2\pi f},}

where:

ω is the angular frequency or angular speed (measured in radians per second),T is the period (measured in seconds),f is the ordinary frequency (measured in hertz) (sometimes symbolised with ν).

Optical detection and SPECTROSCOPY of single molecules and single nanoparticles have been achieved at room temperature with the USE of surface-enhanced Raman SCATTERING. Individual silver colloidal nanoparticles were screened from a large heterogeneous population for special size-dependent properties and were then used to amplify the spectroscopic signatures of adsorbed molecules. For single rhodamine 6G molecules adsorbed on the selected nanoparticles, the intrinsic Raman enhancement factors were on the order of 1014 to 1015, MUCH larger than the ensemble-averaged VALUES derived from conventional measurements. This enormous enhancement leads to vibrational Raman signals that are more intense and more stable than single-molecule fluorescence.

Bcoz the Earth is not a perfect sphere.its shape is oblate spheoid...Since different REGIONS have different DISTANCES from the centre the action of the gravitational PULL differs..Thank U..

Hola!!!


ANS is C. the velocities between them.

Actually you need MASS of TWO objects and the distance between them so there is no need to CALCULATE velocity.

By INCREASING the DISTANCE between LINE of ACTION and the axis of rotation

I don't KNOW TRY SEARCHING in chromy

We know that
electrostatic force
f = E.q
ma = E.q
a = E.q/m
in a UNIFORM electric field, E will be CONSTANT and also
m is constant
so
a is DIRECTLY proportional to q

For developing countries like India, wind turbines OFFER an attractive source for power production. The country's current generating capacity is about 105,000 MW (as of March 31, 2001), but this needs to be doubled in the next 10–15 years to meet a situation of “power on demand”. Both central and state agencies, various private and public sector COMPANIES are now considering the installation of wind FARM projects for power generation. Wind farm projects with a capacity of 990 MW have already been installed by private companies for power generation. As a result of the initiatives taken by the government to promote wind energy, different states are now supporting the wind power companies and investors with LIBERAL policy initiatives, THOUGH there are minor irritants that have to be sorted out. The government has taken some recent measures to eradicate these irritants and to promote wind power in India. This article reviews current Indian status of wind energy, the various hindrances in its smooth development, the initiatives taken by the government to remove them, and future development prospects of wind energy in India.

Hi there !!
Here's your answer

The correct OPTION is (B) 18N

Method:

GIVEN,
MASS of tricycle (m) = 15KG
Acceleration (a) = 1.2m/s²

We know,
Force = mass × acceleration
F = ma
F = 15kg × 1.2m/s²
F = 18kgm/s²
F = 18N

The velocity of an object is the RATE of CHANGE of its position with RESPECT to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion.....any more detail try INTERNET

There are a few ways to do this. 

i) observe that the acceleration is 9rad/s / 3s = 3 rad/s², so 
Θ = ω₀*t + ½αt² = -9rad/s*10s + ½ * 3rad/s² * (10s)² = 60 rads 

ii) It gained 15 rad/s over 5 s, so by 10 s it will GAIN another 15 rad/s with a final velocity of 21 rad/s. Then 
Θ = ωavg * t = ½(21 - 9)rad/s * 10s = 60 rads 

iii) the area under the t-axis is ½ * -9rad/s * 3s = -13.5 rads 
and the area over is ½ * 21rad/s * 7s = 73.5 rads 
so the net area = ANGULAR distance = 60 rads

I don't KNOW ASK your TEACHER

Heya
I SUPPOSE that C should be the ANSWER...
HOPE it HELPS...

Rest and motion are RELATIVE TERMS. Explain. ANSWER: Rest and motion arethe relative terms because they depend on the observer's frame of reference. ... So if two DIFFERENTOBSERVERS are not at rest with RESPECT to each other, then they too getdifferent results when they observethe motion or rest of a body.

Heya
here's your ANSWER...
but I'm only aware of the advantages so can only tell you that...
Advantages: Higher FIBRE content laminates can usually be achieved than with standard wet lay-up techniques. ... Better fibre wet-out due to pressure and RESIN FLOW throughout structural fibres, with excess into bagging materials. Health and safety: The vacuum bag reduces the amount of VOLATILES emitted during cure.
