Answer:
e = 1.21 mV
Explanation:
given,
length of rod = 10 m
height of drop = 4.89 m
Earth’s magnetic field = 12.4 µT
acceleration of gravity = 9.8 m/s²
velocity of the beam
v = 9.79 m/s
emf of the beam
e = B l v
e = 12.4 x 10⁻⁶ x 9.79 x 10
e = 1.21 x 10⁻³ V
e = 1.21 mV
Answer:
18feet
Explanation:
We need to find the distance,c between the vertex and the focus.
For a vertical parabola:
#If we place our parabola at the center, the expression changes to:
The points of the parabola are given as (12,2), substitute in our equation to find c:
Hence, the receiver should be placed at 18ft
