    Understanding Orbital Wavefunctions in Quantum Mechanics

    Sir i have learned that wave function has no physical meaning its only its square that makes sense, why its square in particular and not a cube? How was so the concept of wavefuntion put forward?

    Understanding Orbital Wavefunctions in Quantum Mechanics

    I have poor concepts in Orbitals, wavefunctions etc. What i know is that quantum mechanics(study of sub atomic particles) talks about probability. What i understand is wavefunction means probability of finding an electron in space around a nucleus, correct me i am wrong.So when we say that this...

    Finding initial velocity of body thrown upward for 10 seconds

    So either you take a single parabolic path or take motion along x and y axis, its one and the same thing.

    Finding initial velocity of body thrown upward for 10 seconds

    From down to up we have u=u, v=0 (velocity at top is 0, it is momentarily at rest at that point), (Here)t=10/2=5s, g=-10m/s(as direction of u is opposite to acc or force of gravitation) so we have: v=u+at 0=u-10*5 u=50 Also when you will check motion from up to down you will get the same 'u'...

    Finding initial velocity of body thrown upward for 10 seconds

    Okay let me correct it a bit...Projectile is motion in 2D, you can divide this motion along separate x and y axis, and apply equations of constant acc. accordingly along both directions. If you have any problem getting it, go through the derivation of projectile formulas.

    Projectile Problem: Horizontal Velocity Analysis

    In this graph of Vx vs time, Vx is along y-axis and t is along x-axis, now the y-axis is cut on only one point, this signifies that its value will remain constant or same(equal to y coordinate of that point) even if time is increasing. Thats why it is represented as a horizontal line parallel to...

    Finding initial velocity of body thrown upward for 10 seconds

    vf is the velocity at the max height of the parabolic path bro.

    Finding initial velocity of body thrown upward for 10 seconds

    Here u got to consider the motion in two parts, 1. From down to up and 2. Up to down From down to up we have u=u, v=0 (velocity at top is 0, it is momentarily at rest at that point), (Here)t=10/2=5s, g=-10m/s(as direction of u is opposite to acc or force of gravitation) so we have: v=u+at...

    Motion Problem Constant Acceleration from 10 to 50 m/s in 2 secs

    Check this: We have three equations of motion for constant acceleration along 1D, 1. v=u+at, 2. v*v - u*u=2as, and 3. S=ut + 1/2at*t okay Here u(initial velocity)=10m/s, v(final velocity)=50m/s, a=constant (so apply equations as it is a 1D problem), s=60, t=? Using eq. 2 we get...

    High School Is 220V household voltage the same as potential difference?

    In Indian standard electric supply at homes is of 220V and 50Hz, What is the physical meaning of Voltage 220V? Does Voltage means Potential difference? I know that potential difference(pd) between two points is the work-done per unit charge to move it between the two points. Is 220V the pd...
