The first huge advantage of the Hubble law is the ability to see objects without the obscuration of the atmosphere, the atmosphere distorts and obscures a great deal of light from distant and dim objects. By placing the telescope outside the atmosphere this problem is eliminated, also the Hubble being space based can observe phenomena that might be completely missed by land based telescopes because they occur during daylight hours at the land based location. There is no daytime obscuration of the stars from space.
Answer:
Explanation:
Moment of Inertia about an axis passing through its center and Perpendicular to its Plane is given by
As all the mass is at radius therefore its moment of inertia is more than the moment of inertia about a axis parallel to the Plane
According to perpendicular axis theorem
and 
is same due to symmetry
thus 
thus Perpendicular z axis will have more moment of inertia
Answer:
The continental drift is a geological theory according to which the continents would move with respect to one another. It was introduced, in its modern version, in 1912 by Alfred Wegener, who was the first to present the evidence of the phenomenon and a coherent explanation of its causes in an organic formulation. In modern science the theory of continental drift is replaced by the more general theory of plate tectonics.
1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.
3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.
4. A medium
5. Vibrations
6. All
7. Faster
8.Their kinetic energy increases
9. Conduction, convection and radiation
10. The heating of metals in the mantle, creates a current which slowly moves the plates above it.
<h3><u>Answer;</u></h3>
= 64 N/m
<h3><u>Explanation</u>;</h3>
According to Hooke's Law for a helical spring or an elastic material, extensional force is directly proportional to the distance the material has extended.
F = ke; where F is the extension force, k is the spring constant, and e is the distance extended.
Thus;
k = F/e
= 44N/0.69 m
= 63.768 N/m
<u>= 64 N/m</u>
