What else can I help you with?
What kind of lens should be used if you want to make fire with the help of lens using the rays of the sun?
You should use a convex lens to focus sunlight into a concentrated point to make fire. The curvature of the lens helps converge the sunlight, increasing its intensity at the focal point. This concentrated heat can then ignite a flammable material.
How do you visualize a psi ball?
To see the Psi ball you must totally focus and concentrate on it, Hours of Meditation would increase your chance of doing so. If your interested in doing this kind of stuff i recommend that you start with less challenging practices and learn about the body and its chi points and how to use them.
What is the earliest source of energy used by man was?
Depending on what kind of energy you are talking about... For millions, nay billions, of years, our ancestors ate food, so the energy source would be anything from which we got food. If you mean other than food, like technological uses, that would probably be wood, used to make a fire.
What kind of heat you feel when you put your hands above a fire?
You will feel radiant heat when you put your hands above a fire, which is heat transferred through electromagnetic radiation. This type of heat warms your hands by direct exposure to the fire's energy.
Which kind of heat transfer causes smoke to rise from a fire?
Convection is the heat transfer process responsible for causing smoke to rise from a fire. As air near the fire gets heated, it becomes less dense and rises, carrying the smoke along with it.
What kind of lens would let you focus the sun rays light to start a fire?
A magnifying lens, like a Fresnel lens or a convex lens, can concentrate sun rays to create a focal point that is intense enough to start a fire. This works by focusing sunlight onto a small area, increasing the temperature and igniting flammable material like paper or dry leaves.
How would one extinguish a kitchen pan fire?
A kitchen pan fire is most likely caused by grease. The best option for putting out this kind of fire would be a fire extinguisher. Never use water on these kind of fires.
Can you have a fire in an incinerator in a garden?
It would depend on the kind of garden you have.
In olden days civilizations in south America use a lens to start a fire what kind of lens did they used and how did the fire start?
Well what u are refrerring to is the process of refraction. They would be using a convex lens. this lens has the ability to refract all the light rays which come from a far distance (known as infinity in physics) towards a common point (called focus). So obviously if all the rays reaching the lens from the sun are refracted by a convex lens they would heat up the point at which all of them converge. this started a fire. this can also be done with a magnifying glass as that also has a convex lens.

What kind of mineral can be set on fire?
Coal would be one example.
What kind of degree do you need to become a actress?
Majoring in Theatre or Film with a focus on acting would be a good way to start. Different companies have different requirements for their actors, so it would also depend on where you're hoping to work.

A parabolic mirror would do the job.
What ways could early man kind start a fire?
smashing stones together , turned out they were flint
In olden days civilization in South America used a lens to start fire.what kind of lens did they use and how did the fire start?
They Used a Convex Lens
Why does the hose in the fire engine not catch alight?
because the hose is fire-retardant. I would see it as kind of pointless to have a fire-hose that catches on fire. it just... defeats the purpose
What kind of bear is a fire-preventing bear?
I would say Smokey the Bear, that's who.
