Answer: a = 1, b = 9, c = 6, d = 4
Explanation:
With no velocity, total mechanical energy is all gravity potential energy
PE = mgh = 80.0(9.81)(25) = 19,620 J = 1.96e4 J
The answer is: Renewable energy resource.
The explanation for this completion exercise is shown below:
By definition, the Renewable energy is that the energy that is obtained from renewable resources. Renewable energy sources has taken on importance in recent years and plays an important role in the sustainable development of the planet.
Therefore, Agricultural waste used as fuel is an example of a Renewable energy resource, because you can obtain low emissions but high efficiency.
Answer: 30.641
Explanation: If you get the ave which is 38.0 then the vi which is 7.359
38.0-7.359=30.641/0.0 which is 30.641
It can be explained as follows: consider the field produced by a positive charge. If we place a positive test charge in this a field, then this charge would move away from the central charge (because like charges repel), while if we place a negative test charge in this field, this charge would move towards the central charge (because opposite charges repel)
Explanation:
Electric fields are vector fields, and they are represented using field lines.
The field lines give indications on both the magnitude and the direction of the electric field. In fact:
- The magnitude of the field can be inferred from the spacing between the lines: the closer the lines are, the stronger the field, while for a weaker field the lines are more spread apart
- The direction of the field is given by the direction of the field lines
In particular, by convention the direction of the field lines represent the direction of the force that a positive test charge would feel when immersed in that field: this means that a positive test charge would accelerate in the direction of the field lines, while a negative test charge would accelerate in the direction opposite to the field lines.
This is in agreement with the fact that like charges repel and opposite charges attract. In fact, the lines of the electric field produced by a single-point positive charge point away from the positive charge: if we place a positive test charge in this field, then this charge would move away from the central charge (because like charges repel), while if we place a negative test charge in this field, this charge would move towards the central charge (because opposite charges repel).
