Answer:
infinity
Explanation:
Given that
Resistance = R
Resistivity = ρ
Length = L
Diameter = d
The resistance of wire R given as

A=Area

Now by putting the value of A


When d tends to infinity then d² will also tends to infinity.
So when d tends to zero then the resistance tends to infinity.
Therefore answer is ---
infinity
Answer:
time of flight of a pulse, and these most often
involve triggering of the measuring oscilloscope
with the signal that generates the sound pulse and
timing the time delay of the pulse picked up by a
conveniently placed microphone45
. Loren Winters
has reported a method similar in principle to the
present one, but which uses a completely different
detection system6
.
Explanation:
63 hertz.
This is because a hertz is how often a sound wave repeats.
Answer:
The answer to your question is 404.2000
Answer:t=0.54 s
Explanation:
Given
Jacob is traveling 5 m/s in North direction
Jacob throw a ball with a in south direction with a velocity of 5 m/s
Ball is thrown in opposite direction of motion of car therefore it seems as if it is dropped from car as its net horizontal velocity is 5-5=0
Time taken by ball to reach ground



t=0.54 s
Motion of ball will be straight line
