What type of reaction is being shown in this energy diagram
Explanation:
- Final velocity, v = 200 m/s
- Initial velocity, u = 0 m/s [Starts from rest]
- Acceleration, a = 6 m/s²
<u>To calculate</u> : Time (t)
★ v = u + at
→ 200 = 0 + 6t
→ 200 = 6t
→ 200/6 = t
→ <u>33.34 s ≈ t</u>
Answer:
The forces experienced by the middle particle are attractive, and the net force will remain the same (0) if and only if the distances of the sides particles to the middle particle are the same.
Explanation:
In example 20.3 the forces experienced by the middle particle are repulsive because all the particles are positive, for the case in which the particles on the sides are replaced for negative charge particles the forces experienced by the middle particle are attractive. Regarding the net force, because we don't know the distances we can not give a definitive answer, what we can say is that if the distances from the middle particle to the sides particles are the same the net force is zero for both cases (remain unchanged).
Explanation:
8. correct. You can get there from Maxwell's equations, a derivation that is beyond the scope of this answer.
___
9. Color is a property of visible light, the portion of the electromagnetic spectrum that has particular effects on the eyes and brain. Other portions of the spectrum, those observed by radio and X-ray telescopes, must be rendered in false color to make an image. The appropriate choice is the first one:
• radio telescope and X-ray telescope
