Pademelons are like small wallabies and can be found in New Guinea, Tasmania and the east coast of mainland Australia.
Light travels at about one billion kilometres per hour.
The event horizon is the point of no return around a black hole, which nothing can escape from.
The angles in a triangle must add up to 180 degrees. As a right angle is 90 degrees, and a triangle has three angles, the maximum must be one right angle. Otherwise, if there were two 90 degree angles, it would add up to 180 degrees and there would be nothing left for the third angle.
Sodium is a silvery-looking metal, but it’s very reactive so it’s rarely seen in its pure form.
Herpetologists study reptiles and amphibians, including lizards, turtles and frogs.
The ozone hole has been slowly healing since the 1990s, but it may take more than 50 more years to heal completely.

Question 10: I think you should specify that said triangle is on a flat plane, since it’s possible to have more than one right angle on different planar geometries.

Oh, I didn’t realise the questions change on each reload – my previous comment was in regards to the maximum number of right angles that a triangle can have.

Yup, on a sphere you can have three right angles – on the Earth, Singapore, Kinshasa and the South Pole makes a triangle with three almost-right angles!
