What is translocation in soils?
What will be an ideal response?
Translocation of materials within the soil profile is primarily
due to gradients in water potential and chemical concentrations
within the soil pores

Suppose that in a parallel universe, the proton and electron were identical to their counterparts in our own universe EXCEPT that the electron had twice as much charge as our electron. In our present universe,
the radius of the first Bohr orbit for hydrogen is a0 and the speed of an electron in that orbit is v0. In the parallel universe (a) what would be the radius (in terms of a0 ) of the first Bohr orbit for hydrogen? (b) what would be the speed (in terms of v0 ) of an electron in the first Bohr orbit for hydrogen?
What is the average power dissipated by a 25-? resistor in an LRC series ac circuit for which the power factor is equal to 0.25 and the maximum voltage of the ac source is 8.0 V?
A) 0.16 W B) 0.040 W C) 0.62 W D) 0.080 W E) 0.32 W
In outer space, you observe a straight stream of electrons flowing past you at 14.5 miles per second, about the same speed that Mars moves on its orbit around the sun. 
You maneuver your spacecraft to face the current so that the electrons are moving from left to right and so that you are 10 m from the stream. Now you fire your rockets and boost your speed so that you are also moving at 14.5 miles per second, exactly at the same speed and direction as the electrons. In what direction does a compass needle point now?
A. right 
B. down 
C. left 
D. up 
E. You observe no magnetic field
