Answer:
Systematic errors.
Explanation:
The density of the aluminium was calculated by a human and this is not natural but can be due to errors in the calibration of the scale for measuring the weight or taking readings from the measuring cylinder.
Random errors are natural errors. Random errors in experimental measurements are caused by unknown and unpredictable changes in the experiment. Systematic errors are due to imprecision or problems with instruments.
Answer:
D: Increase the distance between the objects.
E: Decrease the mass of one of the objects.
<h3><u>Answer;</u></h3>
producing a path for current to flow
<h3><u>Explanation;</u></h3>
- An AC generator is a device that converts mechanical energy into electrical energy using the principle of electromagnetic induction.
- <em><u>Slip rings are two hollow rings to which two ends of the armature coil are connected. These rings rotate with the rotation of the coil. They function to to allow for electrical contact with the brushes.</u></em>
- Slip rings therefore, provide a means for connecting the rotating armature to an external circuit.
