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: I would say static electricity.
Explanation:
Weight of a person on the earth is given by,
W= mg,
Where, g is the gravitational acceleration of the earth and m is the mass of the person.
Gravitational acceleration of the moon is one-sixth of the earth.
Therefore, the weight of a astronaut who goes to the moon will be one sixth of that on earth. Hence, the astronaut will weight less.
Given:
m = 0.14 kg
v = 18 m/s
To find:
Kinetic energy= ?
Explanation:
Kinetic energy of the object is possessed when the object is in motion. It is define as the work done required to accelerate a body from rest to motion. Unit of energy is Joule and it is same as unit of work done. Energy is nothing but the capacity to do work.
Solution:
Kinetic energy of the ball is given by,
Kinetic energy = 
m = 0.14 kg
v = 18 m/s
Kinetic energy = 
Kinetic energy = 226.8 Joule
Answer:
(a): The frequency of the waves is f= 0.16 Hz
Explanation:
T/4= 1.5 s
T= 6 sec
f= 1/T
f= 0.16 Hz (a)
