Answer: depth= 1875m
Explanation: divide t by 2 because its echo it will go and come back thats why we divide it with 2
Then apply formula Depth(d)=velocity (v)/time (t)
Putting values we get ,
d=1500/0.4
d=1875m
The astrometric technique of planet detection works best for massive planets around nearby stars.
Answer:
I=0.05 Amper
v=9 volts
Explanation:
I=V/R1
l=6/120=0.05Amper
voltage of 180ohm =IR2=0.05×180=9volts
