If it is indicated that the radius of a disk is (10.0 ± 0.1) cm, its thickness (10.0 ± 0.1) μm and its mass density 0.001 kg/m3, how many significant digits will you use to express its estimated weight from these data?
(1 - 3) |
1

How you will express the result of 1.20 kg - 0.02 kg?
(1.2 - 1.18) |
1.18
|
|
When performing calculations with numerical data, before reporting the result of the calculation, does it make sense to use as many digits as possible?
(Yes - No) |
Yes
|
|
Would you use a temperature data logger for implementing a real-time negative feedback controller of the temperature in a room?
(Yes - No) |
No

If a constant current flows through a wire, is the dissipated power in it proportional to the cross-section area of the wire?
(Yes - No) |
No
|
|
A person wearing shoes touches the metallic chassis of an electrical device in which both the live and the neutral power conductors are accidentally shorted to that chassis. Which kind of hazard do you think is more likely if the protection mechanisms of the power network fail?
(Electrocution - Fire) |
Fire

(Yes - No) |
Yes
|
|
Measurements from system A produce the following values (4.04; 4.05; 4.07, 4.03) and measurements from system B produce the following values (4.001; 4.002; 4.001; 4.001). Can you state that system B appears to be more precise than system A?
