Answer:
Part a)
Induced EMF when length vector is along Z direction is 0.72 V
Part b)
Induced EMF when length vector is along Y direction is ZERO
Explanation:
As we know that the motional EMF induced in the wire is given as
1)
As we know that
now we have
so we have
2)
If the length vector is along Y direction then we have
so again we have
so we have
EMF = 0
Answer:
specific gravity = 0.8
specific gravity of solution = 2
Explanation:
given data
rectangular block above water = 0.400 in
rectangular block below water = 1.60 in
material floats below water = 0.800 in
solution
first we get here specific gravity of block that is
specific gravity = block vol below ÷ total block vol × specific gravity water ..............1
put here value we get
specific gravity = × 1
specific gravity = 0.8
and now we get here specific gravity of solution that is express as
specific gravity of solution = total block vol ÷ block vol below × specific gravity block ........................2
put here value we get
specific gravity of solution = × 0.8
specific gravity of solution = 2
