What is exactly mass spectograph?

how it works?

the parallatic angle substanded by distant sta is 0.86" on the earth's orbitical diameter (1.5X1011) . the distant of a star from the earth is explain this Q ? and it solution

This is the Given Problem I Solved At The End Calculate By Logarithms Method.

The Given Answer is 26.82 m/sAndMy Answer is 27.81 m/s. The Total Difference is 0.99 in the answer Is it correct answer ? (If my answer is incorrect give me correct solution to the problem). My Answer is submitted in JPG Image.Show that 1 dyne/cm2 = 0.1 N/m2

whate is parallax? how to take measure of parallax

Q. The values of measurement of a physical quantity in 5 trials were found to be 1.22, 1.23, 1.23, 1.24 and 1.25. Then pick up the incorrect answer-

1) average absolute error is 0.01

2) relative error is 0.01

3) percentage error is 1 %

4) percentage error is 0.1 %

derive an expression of kinetic energy of a BODY OF mass'm' and moving with velocity 'v' ,using dimensional analysis.

error in calculation is unclear to me.....

what is the meaning of n,m,q dimention?

of kinetic energy

^{n}is dimensionally consistent : E^{2}= (mc^{2})^{2}+ (pc)^{2}where E, m and p are the energy, mass and momentum of a particle, respectively and c is the speed of light in vacuum.A science student takes 100 observations in an experiment. Second time he takes 500 observations in the same experiment, by doing so the possible error becomes -

1) $\frac{1}{5}times$

2) 5 times

3) unchanged\

4) none of these

the heat generated (H) in a wire of resistance (R) when a current (I) flows through it for a time (t) is given by H=I^2Rt. Show that the quantity H has the same dimension as that of energy.

x-axis with speed 6 m/s for the first half distance of a journey and the second half distance with a speed 3 m/s. The average speed in the total journey is(1) 5 ms/ (2) 4.5 m/s (3) 4 m/s (4) 2 m/s

from hsc board ]Q.29. Suppose the kinetic energy of a body oscillating with amplitude A and at a distance x is given by k = $\frac{Bx}{{x}^{2}+{A}^{2}}$. The dimensions of B are the same as that of -

1) work / time

2) work $\times $ distance

3) work / distance

4) work $\times $ time
