Partial eclipse, Annular eclipse,
Total Eclipse and Hybrid Eclipse are the four different
types of the eclipses. When the Sun and Moon are exactly in line with the Earth, the annular eclipse occurs.
The new moon is invisible from the earth and it is silhouetted against the sun,
this can only be seen in annular eclipse. Annular word means ring shaped, we
can see a dark ring of fire in annular eclipse. It has five different stages
that are first contact, second contact, maximum eclipse, third contact and 4th
contact.
Wavelength of any wave = (speed) / (frequency)
Speed of light = 300,000,000 m/sec
Wavelength = 3 x 10 to the 8 / 750 x 10 to the 12 = 4 x 10 to the -7 or 400 nanometers.
The middle or centre of the Earth is the core. However the middle of the layers from the surface to the centre of the Earth is known as mantle.
Answer:
0.015 m/s2
Explanation:
Using Newtons 2nd law.
F = ma where F = Force applied, m = mass of the object and a = acceleration acquired.
So substitute the values in SI units.
m = 
kg
Therefore F = 0.003×5 = 0.015 m/s2
