A solar eclipse occurs when the moon crosses in front of the Sun, blocking some or all of its rays. A lunar eclipse happens when the moon is directly behind the earth, blocking the moon from receiving light. The only light comes from the light on earth's reflected shadow.
You can look at a lunar eclipse because there is very little light or none at all. You can't look at a solar eclipse because you are looking directly at the sun unless it is complete. Before totality, only some of the Sun is blocked, causing your pupils dilate to let in more light. Since they do this, more of the Sun's rays can be let in to the eye, which effectively allows your eyes to burn.
Some doctors and eye care specialists say that after someone complains of blindness after looking at a solar eclipse unaided, they can see what the Sun and moon looked like at the time that they looked at it, as it is burned onto their retinas.
You would make rings of clay and then place the beads on the rings (one on each) at various places and one in the center for the nucleus.
Answer:
1.75 m/s
Explanation:
k = Spring constant = 490 N/m
m = Mass of object = 5.8 kg
x = Displacement of spring = 0.19 m
v = Speed of object at the equilibrium position
The potential energy of the spring will balance the kinetic energy of the mass
The speed of the mass as it returns to the equilibrium position is 1.75 m/s.
Answer:
He is wrong!
Explanation:
Frequency refers to how many wave lengths pass in a second and speed is how fast the wave is traveling for example the speed of light goes really fast but has a mid-level frequency.
Hope this helps! ;-)
Answer:
52.4
Explanation:
we ignore 322 and 19 because they are much bigger or smaller in value. we have to find the average of the rest numbers:(52.3+52.5+52.2+52.6)/4=52.4
