Answer:
The brightness of a light depends on the amplitude of the light wave, which is the extent the waves moves from their equilibrium position. The brightness is also related to the amount of light that is emitted or reflected by an object
Therefore, compared to dim light, light that look bright have a higher amplitude and emit or reflect more light energy (photons)
Explanation:
Answer: A <u>Nebula </u>is left behind. A spectacular explosion in which a star ejects most of its mass in a violently expanding cloud of debris.
Hope this helps!
The student's answer is wrong because the unit of his answer is meter - seconds which is not unit of distance (meter).
<h3>
Total distance traveled by an object</h3>
The total distance traveled by an object projected upward is calculated from third equation of motion a shown below.
<h3>Equation for the motion of the object</h3>
v² = u² - 2gh
where;
- v is final velocity
- u is initial velocity
- g is acceleration due to gravity
at maximum height, the final velocity is zero, v = 0
0 = u² - 2gh
2gh = u²
h = u²/2g
The equation for the total distance an object has traveled during upward projection is "h = u²/2g".
<h3>Dimension of the student's answer;</h3>
d = (2vh)/g = (m/s x m) / (m/s²) = (m²/s) / (m/s²) = m.s
Thus, the student's answer is wrong because the unit of his answer is meter - seconds which is not unit of distance (meter).

Answer:
tectonic plates move in opposite direction
Tectonic plates are not necessarily moving in opposite directions, but if there directions are different they form plate boundaries. If they were moving in the same direction they would become the same plate. The more opposite the direction, the more obvious the fault.
Examples of plate boundaries:
Divergent: moving away from each other - mid-Atlantic ridge
Convergent: moving towards each other - the Himalayas (Indian plate subducting under the Eurasian plate forcing up the mountains)
Transform: sliding laterally along each other - San Andreas fault
It intimidates other spider because it makes them look bigger than they really are.
