Answers:
a) 10 m
b) time=1.6 s, frquency=0.625 Hz
c) 6.25 m/s
Explanation:
a) If there is a crest at each dock and another three crests between the two docks, and the wavelength 
is the distance between to crests; this means we have 
in 
:
Clearing :
b) This part can be solved by a Rule of Three:
If 10 waves ---- 16 s
1 wave ----- 
Then:
This is the period of the wave
On the other hand, the frequency 
of the wave has an inverse relation with its period :
This is the frequency of the wave
c) The speed 
of a wave is given by the following equation:
Finally:
Answer:
14 hours 18 minutes.
Explanation:
ratio of number of orbits, so it completes 7 orbits in the time Janus does 6.
(16*60+41)*6/7=858 minutes or 14 hours 18 minutes
Answer:
Number value and direction
Explanation:
Vectors are quantities that can be identified by value and direction . Examples are velocity and acceleration
Answer:
-17.5 nC
Explanation:
charge A = -30 nC
charge B = -5 nC
After adding them it would be the average of the two charges because of the getting same voltage difference. so
c = (-30+(-5)) / 2 nC
c= -17.5 nC
answer is -17.5 nC
Answer: It represents the whole distance traveled. Hope this helps!
