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:
The air molecules in the compressions of the second wave are more dense, so the sound is louder.
Explanation:
In a closed room, Noah and Nina are sitting 15 m apart.
As Noah says the same sentence twice, Nina does not hear the sound the first time but she does hear the sentence the second time.
This happens as the air molecules in the compressions of the second wave are more dense. As a result, the sound is louder.
The correct option is ''The air molecules in the compressions of the second wave are more dense, so the sound is louder''
Answer
Given,
Flow rate of river is equal to 300,000 L/s.
Width of river = 18 m
and depth of river = 22 m
a) Average speed of river
Q = 300,000 L/s
= 300 m³/s
Q = Av
b) Average speed when river is widen to 63 m and depth is increased to
- is a measure of the tendency of an atom to attract a bonding pair of electrons.The Pauling scale is the most commonly used. Florine, is the assigned value of 4.0, and range down to cesium and francium which are least electronegative at 0.7 .
