C) is the correct answer.
Answer:
1.9 km
Explanation:
The equation for vertical motion is ...
h(t) = -4.9t^2 +26t +20
This will have a zero near t = 5.988 seconds.*
The horizontal distance traveled in that time is ...
(310 m/s)(5.988 s) ≈ 1856 m ≈ 1.9 km
_____
* The root of a quadratic can be found numerous ways. We choose the quick and easy: let a graphing calculator show it to you.
Answer:
A)What average intensity does a GPS receiver on the ground, directly below the satellite, receive? = 9.75 x 10 ∧-15w/m²
B)What is the amplitude of the electric field at the GPS receiver in part = 2.71 x 10 ∧-6nc
C)What is the amplitude of the magnetic field at the GPS receiver in part = 9.03 x 10∧-15T
D)How long does it take the signal to reach the receiver? = 6.73 x 10 ∧-2s
E)If the receiver is a square panel 2.00 on a side that absorbs all of the beam, what average pressure does the signal exert on it = 3.25 x10 ∧-25pa
F)What wavelength must the receiver be tuned to? = 0.190m

If everything else is held constant ... the substance from which
the conductor is formed, its cross-sectional area, its temperature
everywhere along its length ... then yes, its resistance will be
directly proportional to its length.
