do u have a photo that comes w/ this? so i could help more :) ?

Torque = (force) x (distance from the pivot) = (10 n) x (0.9 m) = 9 newton-meters
Answer:
Random errorrs
1) Variations in the level of the eye when we measure the dimensions of the cubic piece using the metric rule.
2) Possible vibrations or disbalance when we measure the mass of the of the cylinder.
Systematic errors
3) Wrong calibration for the balance and that represent a measurement wrong
Explanation:
Previous concepts
Random error represent an statistical error associated to the effect random in the experiment.
Systematic error is a "repeatable error associated with faulty equipment or a flawed experiment design", so is an error non controlled.
Solution to the problem
So as we can see we have two possible types of errors : random and systematic errors. For this stuation the list of 3 errors required are:
Random errors
1) Variations in the level of the eye when we measure the dimensions of the cubic piece using the metric rule.
2) Possible vibrations or disbalance when we measure the mass of the of the cylinder.
Systematic errors
3) Wrong calibration for the balance and that represent a measurement wrong

Answer:
cos to = $ 24
Explanation:
When replacing the bulb only 25% of the energy is used, therefore
W = 0.25 100
W = 25 W
Let's look for the energy in the life of the bulb
E = 25 10⁻³ 12000
E = 300 Kwh
now we can calculate the cost using a direct proportion rule.
Cost = 0.08 300
cos to = $ 24
