Answer:
diameter of transmission is 3.473 mm
Explanation:
given data
current = 300 A
total wire length = 1.0 m
voltage drop = 0.55 V
solution
as here Resistivity of copper is = 1.68 ×
ohm- m
so we get here resistance of wire that is
resistance =
..............1
R =
R = 1.774 ×
ohm
and now we get diameter of wire that is
R =
.............2
d² =
...............3
put here value
d² =
d =
d = 3.473 ×
m
d = 3.473 mm
so diameter of transmission is 3.473 mm

Answer:
no mam
Explanation:
the answer to the question is
In 6 secs, the dog covers-
S=vt
8.9*6 = 53.4 m.
In the same time, the cat covers, 53.4-3.8 = 49.6 m.
Thus, speed of the cat, v= s/t,
= 49.6/6 = 8.267 m/s
'Controlled Breeding', or selective breeding, is in genetics where people make animals reproduce to make favorable traits appear more often.
