True as the independent variable is over the dependent variable and controls it as the dependent relies on the independent.
The solid cylinder reaches the bottom first.
A solid object will always roll down the ramp faster than a hollow object of the same shape regardless of their exact mass or diameter.
The solid cylinder has a lower moment of inertia than the hollow one does. Although they have the same mass, all the hollow cylinder's mass is concentrated around its outer edge so its moment of inertia is higher.
The velocity would be greater for the material with radius of gyration k is lower of for which the moment of inertia is lower. Solid cylinder with k as 1/2 will have greater velocity as compared to hollow cylinder which has k as 1. As they have same mass and radius their energies at both the levels would remains same including the potential energy and energy lost due to friction.

Construct an hypothesis <em /><em>(Because </em>the magnet wasn't attracted to the door, the door must be non-magnetic.) He has already made an observation (the magnent didn't stick), and already asked a question (<em>Why </em>didn't the magnent stick). However, he has not explained the results (there is no experiment yet).
Answer:
Around solar mass.
Explanation:
In a white dwarf, electron degeneracy prevents the star from collapsing into itself. However, if the mass of the star exceeds the Chandrasekhar Limit, gravity would overcome electron degeneracy and star would collapse further.
The value of the Chandrasekhar Limit is approximately ( times the mass of the sun.) While this mass is the maximum possible mass of a stable white dwarf, the original mass of the star that formed this white dwarf tends to be much greater.
I just googled refraction vs reflection. Hope this helps! :)
