請問幾句數理的問題怎麼翻
1.
A sine wave is passing through a medium above the x-axis at speed V.
The formula for the medium's vibration at time t=0,
is given by y(t)= A sin ((T*pi*t)/2)
Find the formula for y given arbitrary values for x and t.
Then provide the formula that describes the waveform at t=0.
2
A nucleus of helium 42 has passed through an accelerator
and gained kinetic energy e.
It is fired in a vacuum
towards stationary Nnucleus P, which has an electrical charge of Ze.
Given alpha particle charge as 2e, mass as m,
and Coulumb's proportionality constant as k,
what is the voltage at the point when the two nuclei are closest?
3
Find the convergence of the infinite series
Sigma(N) = 1*sin ((n/3*pi)/2) from 1 to infinity.
