The position of a moving particle in vortex is expressed as, x(t) = x0 sin(a√t + bt^2) where x0 isthe position at t = 0, x (t) is the position at time t, and a and b are the constants. Using dimensionalanalysis find the units of the constants a and b?
The planet Venus orbits the Sun in periodic motion (as yearly motion) and simultaneously spins
about its axis (as diurnal motion). Venus has a (yearly) period of orbit of 225 days and a (diurnal)
period of rotation of 243 days. So for Venus inhabitants, a day would last longer than a year!
Determine the frequency of orbit and the frequency of rotation (in Hertz) on Venus.
O For yearly motion 5.1 x 108 Hz,
For diurnal motion
— 4.8 х 108 Hz,
O For yearly motion
+ 1.7 x 108 Hz,
For diurnal motion 1.8 x 10-8 Hz,
O For yearly motion → 2.5 x 106 Hz,
For diurnal motion
+ 1.8 х 107Hz,
O For yearly motion
→ 4.3 x 107 Hz,
For diurnal motion
→ 48.0 x 10-7 Hz,
It changed but I tried putting the right input but it didn’t work so now I have to find what equals to 374J
