The time it takes to burn a piece of paper with a magnifying glass depends on various factors such as the intensity of the sunlight, the distance between the magnifying glass and the paper, and the type of paper. Generally, it can take a few seconds to a couple of minutes to start a fire on the paper using a magnifying glass.
A torch will burn longer if it is made of a material that burns slowly, like beeswax or paraffin, rather than materials that burn quickly, like paper or wood. Additionally, a torch can burn longer if it is designed with a larger fuel reservoir, so it can hold more fuel to keep the flame going. Finally, protecting the torch from wind or other elements can also help it burn longer by preventing the flame from being extinguished prematurely.
Optical fibers are long thin strands of glass or plastic that can carry light for long distances. They are used in telecommunications and networking to transmit data at high speeds.
A standard sheet of paper is typically 8.5 inches by 11 inches in size.
Yes, a paper boat can float on water as long as it is well-made and the paper is not too thin. The boat's ability to float depends on its design and the displacement of water.
Viscous deformation of glass refers to the process by which glass deforms slowly over time when under stress, similar to how a viscous fluid would deform. This deformation occurs at high temperatures, close to the glass's melting point, allowing the glass to flow and change shape. Over long periods, this phenomenon can cause glass objects to sag or slowly change their dimensions.
It depends on the color, so i can't answer that.
Yes it can but only by catching sunlight for a long time on the lens then pointing the magnifying glass at the toast I am 10 years old so very clever

It can take just a few seconds to a few minutes for a fire to start using a magnifying glass, depending on the intensity of the sunlight, the flammability of the material being focused on, and the skill of the person using the magnifying glass.
Type your answer here... A long raincoat ,glasses ,a suit and a magnifying glass .Also a notepad and pen.
It isn't the glass, but what the candle is made from that determines how long it burns.

It's in a different place for each player. Think long and hard about the clues. Also, be sure to use a magnifying glass.
The type of paper can affect how long it burns based on factors like thickness, density, and coating. Thicker paper may burn longer than thinner paper due to the additional material to consume. Coated paper may burn faster or slower depending on the composition of the coating.
A long-sighted eye has a lens of insufficient power so that it needs an extra convex (magnifying) lens to bring objects into focus. A more powerful lens allows objects to be focussed at a closer distance, and that is what a magnifying glass does.
It takes two minutes and two senconds.
TOO long, that is why you should use paper or re-use a glass plate
