Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.

Swatantra Veer Savarkar was an Indian nationalist who played a vital role in the Movement of Nationalism and Independence of India.

The contribution of swatantra Veer Savarkar to Nationalistic historiography included:

(i) Motivated young Indian to join militant struggle against the British.

(ii) Supported Subhas ChandraBose during the demand of release of Indian soldiers during the World War I.

(iii) Initiated the Nationalistic Movements among Indian students.

(iv) Wrote books related to Indian Nationalism; "1857-Freedom of India

Without loss of generality, we only need to look at the equation for the x-position, since we know that centripetal acceleration points towards the center of the circle. Thus, when θ = 0, the second derivative of x with respect to time must be the centripetal acceleration.

The first derivative of x with respect to time t is:

dx/dt = -Rsinθ(dθ/dt)

The second derivative of x with respect to time t is:

d2x/dt2 = -Rcosθ(dθ/dt)2−Rsinθ(d2θ/dt2)

In both of the above equations the chain rule of Calculus is used and by assumption θ is a function of time. Therefore, θ can be differentiated with respect to time.

Now, evaluate the second derivative at θ = 0.

We have,

d2x/dt2 = -R(dθ/dt)2

The term dθ/dt is usually called the angular velocity, which is the rate of change of the angle θ. It has units of radians/second.

For convenience we can set w ≡ dθ/dt.

Therefore,

d2x/dt2 = -Rw2

This is the well-known form for the centripetal acceleration equation.

A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample.

For example, milk (when homogenized) and lotions are both examples of colloidal suspensions. There are no phase differences at the human scale, but neither one is a solution. On a more microscopic scale, you could call the suspended micelles phase boundaries, and in that case might not call the mixture homogeneous.

A fraction (sometimes, a common fraction) is a way of expressing a number that is a ratio of two integers: or or even as. The top (or the first) number is called the numerator, the bottom (or the second) number is called the denominator.

two force are acting on q ,one due to 4q and second due to Q

F1 = 1/4∏ε (4q)q/l2

F2 = 1/4∏ε (Q)q/(l/2)2

= 1/4∏ε (4Q)q/l2

F1 +F2 =0

1/4∏ε (4q)q/l2+ 1/4∏ε (4Q)q/l2=0

Q=-q

The average velocity of gas particles is found using the root mean square velocity formula. μrms= (3RT/M)½

Ve should always be greater than Vrms then only particles will not leave the atmosphere of the planet.

We know that

λν=c

now wavelength= c/v= 3*10^8/10^143*10^-6mOption-A

Using equation of motion:

V = u + at

we haveWriting the equation of motion in vector form.a =(3i+8j) m/s2

v=-4j + (3i+ 8j)1 as u = -4j m/s and t=1 sec

or , v= 3i+ 4j

​so final velocity = (32+ 42)1/2= 5m/s
