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

Answer:
option A
Explanation:
given,
drive 4 km at 30 km/h and
another 4 km at 50 km/h
average speed for the whole 8 Km trip = ?
time for the trip of first 4 km
distance = speed x time
t₁= 0.1333 hr
time from another 4 km trip
t₂ = 0.08 hr
average speed
s = 37.50 Km/hr
Less than 40 Km/h
the correct answer is option A
Answer:
im pretty sure its because wax has i higher melting point therefore it would cool quicker if the temperature dropped more. water has a lower melting point so it takes longer to freeze i think. i hope this helps
C. It acts perpendicular to the velocity and it's directed towards the center
hope this helps :)
Answer:
Explanation:
Let solve the differential equation by separating corresponding variables:
