Answer: To help eliminate subjectivity

Machines capable of manufacturing exactly the same component time after time,
with exactly the resistance you want, would be very expensive, and so would the
products they turn out. A resistor would cost a dollar instead of a few pennies.
The machine itself, and its output, work within tolerances.
The cheapest mass-produced resistors are guaranteed to be within 20% above
or below the resistance marked on them. And you know what ? For most bench-
work and prototyping, that's usually close enough.
Answer:3.185KHz
Explanation:
Where
Length (L) = 2.7cm
Speed (V) = 344m/s
Wavelength of the fundamental standing wave: λ = 4L
λ = 4L
Frequency is the rate per second of a vibration constituting a wave.
Frequency is given as:
F= v/ λ
Therefore,
Frequency= v/4λ
Frequency = 1×(344m/s)/4×(2.7cm)
Convert centimetre to meter
100cm= 1m
Convert Hz to kiloHz
1000Hz= 1kHz
Frequency= 3.185KHz
Answer:
-2.5 m/s^2
Explanation:
v=u + at
or, a=(v-u)/t = (10-40)/12=-30/12=-2.5 m/s^2
Here, '-' indicates deceleration is occurring as the velocity is dropping with time.
Hope, this helps you.
