Knowledge Check The centre of gravity of a uniform ball is: Aat is geometrical centre Bat its bottom Cat its topmost point Dat any point on its surfaceSubmit Name the factors affecting the rate of decomposition
In a relatively short period of time, heavy portions of the ball to be tested will rotate by gravity to its bottom-most position and, hence, the desired axis is vertical and thereby determined and can be marked by any convenient marking method....

The Sun and Earth provide a good demonstration of the difficulty. Earth is in a stable orbit around the Sun and despite the star’s huge size and far greater gravity compared to our planet, it’s thankfully unable to pull us in towards it. What actually falls into a black hole The rea...
The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them. And any one standing on the moon, when it and the sun are both beneath us, would see this our earth and the element of water...
"Achieving such trajectory precision is akin to shooting a basketball from Shanghai to hit a hoop in Beijing, while ensuring the ball's angle and speed upon entering the hoop are correct," said the CASC. After evaluating the rocket's payload capacity, performance capability, and reliability, ...
These observations in combination with the infrared interferometry experiment GRAVITY at the very large telescope interferometer and other experiments across the electromagnetic spectrum might yield proof for the presence of a black hole at the center of the Milky Way. The large body of evidence ...
The Sun serves as a natural reference for the modelling of the various physical processes at work in stellar interiors. Helioseismology results, which inform us on the characterization of the interior of the Sun (such as, for example, the helium abundanc
Through the new Athlete No One Saw Coming campaign, Under Armour wants youth athletes to focus on their own game and block out the toxic comparisons they’re faced with each day. No athlete is more familiar with this pressure than Gold Medalist Jordan Thompson....
Ball lightning A relatively rarely seen form of lightning, generally consisting of an orange or reddish ball of the order of a few cm to 30cm in diameter and of moderate luminosity, which may move up to 1 m/s horizontally with a lifetime of a second or two. Barber pole A thunderstorm...
