Answer:
F=BILsin90 when perpendicular sin90 =1 30T x50x30 so you can get 45000N
Moving fan has rotational kinetic energy
Non moving fan has no energy since it is in rest
First we find the energy level with the following formula, where a is the energy level, n1 is the final energy level, n2 is the starting energy level and r is Rydberg's constant in Joules

We insert the values


The wavelength is found with this formula, where h is Planck's constant and c is the speed of light

Finally we insert the values

Which is the same as 93.8 nm
S= 343m/s
F=256Hz
WL= 343ms/256-1
WL=V/F
= 1.339844m
The vacuoles because the plant's central vacuole is bigger.
